Soap bottle

00:00

Hello everybody and welcome to this tutorial in which I'm going to show you how easy it is to sculpt such a nice looking organic soap bottle in Shapr3D. Topics we will take a look

00:13

at is all the necessary sketches we have to only create. And then how by using the history

00:21

line, step-by-step, we are going to create the building blocks of our design. And then...

00:30

Use these very basic building blocks and start adding all the details, for example, edge roundings,

00:37

inside shelling and fillets. Build the piece outside, create then a functional cap. And

00:45

even, for example, use the ability to resume and suppress features to prototype various

00:55

stages of how elements could be rotated and manipulated. And then we will finish with a

01:03

really nice looking product presentation, adding some colors to the background and materials

01:10

for an adequate color material studies. And with all that said, let's do it. So here we

01:18

are inside a new and empty design. The first thing we want to do is make sure all our snap

01:25

options are turned on. and also our unit system is set to millimeter. A bottle is a revolve

01:33

body. So the easiest way to start is by going to the front and creating the front profile

01:40

to revolve. I moved the screen down a little bit. Go to Sketch and we will start with the

01:47

Line tool. At the center of the sketch where Z and X meet, and draw a line to the left side.

01:54

Select the first point that is the center of my bottle and hit the lock icon. Because this

02:02

point, I never want to move. This line, I will dimension to 30 millimeters, select the line

02:10

and also constrain it to be horizontally aligned. I can zoom out a little bit. Then I draw a

02:17

line straight up. This line will be 100. 50 millimeters and vertically constrained, zoom

02:24

out a little bit more. And then on top, I can draw a line to the left side. Make sure this

02:32

is horizontally constrained. And this is 15 millimeters. This is, for example, the top

02:42

diameter and 30 is the bottom diameter. And the 150 is the height of the body. Since we

02:49

have the line tool active, we can zoom in to the top and put in the preliminary geometry

02:56

for the cap. This will be 40 millimeters up, horizontally constraint. Then I can go to the

03:06

right side and go down and make sure that these two lines are horizontally, vertically constraint.

03:14

So now as you can see, I have 150. and I have 40 millimeters. To show the dimensions all

03:23

the time, we can turn on, always show the dimension,

03:29

also always show the constraints, or leave this off. And then when we select a line, we see everything that is important. We can now

03:41

go ahead and create the spline to sculpt the shape of our bottle. Go to the spline icon,

03:50

double tap it, and then you have the option between the control and the fit point. We're

03:55

going to use the control one. So what I will do is from the top, I start drawing and then

04:02

press, go down, press, go to the center and inwards, press, go down, outwards, press, go

04:09

down, press, go to the end and release. And you see this creates a really beautiful shape.

04:19

What I can do now is play with the distance of how far these points are apart from each

04:25

other. So here I will make this a little bit smoother by bringing these points down. So

04:34

they all have exactly a similar distance to each other. On top, I would like to have a

04:40

sharper corner. and also a nice and long part on the curve. So there you see the distance

04:48

is actually much longer between these two points, then these two points.

04:56

And then with this one here in the center, I can play with how much this belly's in. And

05:05

that, for example, is in the space where the fingers kind of like go around the bottle.

05:11

At this point, we kind of like have everything to make a quick prototype. So we'll select

05:18

in the sketch profile of the bottle, then select a vertical line or the Z axis and click Revolve.

05:29

This hides the sketch. So we can show the sketch one more time. And then select the sketch profile

05:38

again. Select an axis and revolve. What is really nice is we can then go ahead and select the

05:55

sketch. Go into Sketch Edit mode, select nothing. And then when we select individual points,

06:02

we can move them around and see how this does update. the shape of our bottle on the fly.

06:11

That's actually really beautiful. Even while history-wise, the sketch is created in front,

06:22

so before the revolve bodies, we can edit steps at the beginning and see how this influences

06:30

the rest of the construction in real time. This is super amazing.

06:39

This bottle is very round and all I want is from the front to see this nice curvature look,

06:45

but actually from the side should be more flat. So I need another sketch. We'll go to the bottom.

06:55

Then I will go to Sketch. And you see, actually,

07:00

when I do this, I have all these sketch intersections to prevent, for example, any... Accidental snapping,

07:08

I can turn everything off and then actually create the circle. So I don't snap to a piece of a sketch or geometry where they intersect.

07:22

Change my view, rotate, exit the sketch. Then I can show everything. And you see that the

07:28

sketch also sits actually directly at the bottom of the bottle. So... and just select the sketch

07:36

and you see where it intersects with the bottle. This is a new profile to select. And that's

07:46

not really what I want. So what I will do is I will select the sketch, exit it, and then

07:52

simply move this down a little bit. How much is up to you. Beautiful. You see now I have

07:59

just one sketch profile. So. Let's select a sketch. Going back to the bottom view. And

08:10

with the spline command, I can now go ahead and draw myself a nice curve.

08:23

And there, beautiful.

08:28

When these two splines are not... connected via a symmetry constraint. I can model every

08:37

spline basically independently. And if I would like the front and the back spline, kind of

08:47

like function, like a mirror, then I have to create a Y and an X symmetry. So let me show

08:54

you how we can do this. This is very easy. So I will select the Line tool along the Y axis,

09:00

I make a line, and along the X axis, I make a line. I select both lines and lock them so

09:06

they don't move. Now select nothing. Then I select two pairs of points, symmetry and the

09:15

X axis, the opposite symmetry axis and the center points and this axis line. When I now select

09:27

one point, you see the opposite moves. But you see here, when I go left and right, the right

09:37

point doesn't move. So this is actually now where we will select the left and right points,

09:45

symmetry, and then we log this to the other line. And then when we go ahead and move these

09:52

corner points, There we are. Now I can go ahead and for example, move this one up, move this one down or stretch this

10:04

out. And by this, essentially with this line can project how I'm going to slice the bottle.

10:14

So let's do this. We will exit the sketch, select nothing, select the sketch profile. And then

10:22

hit the up arrow, Extrude, and then we cut through the bottle. Obviously, I don't want to remove

10:30

the bottle. I want to remove the outside. So by clicking on this tiny icon with the white

10:39

sphere and the blue cube, I can then get into the... Boolean command and decide to add a

10:47

union, new body, subtract. And actually I would like to use the intersect command. And that

10:54

basically gives me the volume of how these three objects, so the cap, the bottle and the thing

11:01

I extruded intersect. Beautiful. Again, one little tiny demo. When I go back to... editing

11:13

my sketches, I see everything in real time. It's actually really nice how this works. And

11:23

the same is also true for this one here. I don't have to go even into a 2D view. I can prototype

11:33

this by selecting the sketch, going to Sketch Edit, and then I use the grid for the movement.

11:43

Perfect. So this looks pretty good. So we have the main bottle and the cap, but we don't really

11:55

have the neck that goes onto the bottle. And this is where I will go ahead and then select

12:04

the first sketch we created and edit it and create two more lines that go inside. One line.

12:13

to here, this should be 11 millimeters and horizontally

12:19

constrained. And then one line straight down, vertically constrained. And this line should be 30 millimeters.

12:34

When I now open the history, you see, I have my first sketch, my two revolutions, my second

12:40

sketch, the extrusion. And when I click on the first revolution, there I see that this is

12:47

actually the feature that created the main bottle. I click on the arrow on the right side to expand

12:56

it. Here I have Profile and Axis. Click on Edit for Profile, and then I will add this sketch

13:05

profile I just created to it. Click Done. And I have updated my design. That's how easy you

13:13

can create different iterations. And you start with very basic models. And then step by step,

13:21

we create more refined complex models. So let's actually refine this bottle. I will turn all

13:33

the sketches off. So I only see this bottle and I can pay attention to how... these edges

13:42

all meet. There are various different ways how we can fillet them and round them. We want

13:49

also later to shell the inside. So before we do our shelling, we want to round all the sharp

13:56

edges on the outside, because then the shelling command does the work of the inside, because

14:03

the rounded edges will shrink down to the inside. And we'll see this in a moment.

14:12

When I select this edge, just as a demo, just don't follow it, just take a look. You see

14:18

how I can round this vertical edge. Then I get these nice rounded corners, edges, and then

14:28

I can round this a second time. And then what you see is we get this connection where we

14:36

have kind of like... two profiles which are rounded, and then this centerpiece. We have

14:44

here very sharp corners. That's not really very nicely looking. So I undo everything. We can

14:52

actually select all edges at the same time. There we are. And then we drag the arrow to

15:04

round this. and pay attention to how this looks. This is nice. And then we click the clock icon

15:13

and switch the corners from Rolling Ball to Setback. Takes a moment to calculate and take

15:22

a look at these beautiful corners. They look actually really great.

15:33

We want to adjust... the radius of the fillet, we can go to History, look where the fillet

15:38

comment is, click on the arrow to expand it, and then change the radius. There we are. It's

15:48

very easy.

15:55

We could also select a face of that fillet. And there you see it says, Edit Fillet. When

16:02

we click on this, Then there we go back to the original command and here we can change that

16:09

value. So same thing. So this is actually done. That's good. This corner we can keep sharp.

16:19

That is fine. This one I would like to round a little bit, one millimeter. This looks sufficient.

16:25

And now actually the bottle is ready to be shelled. So I can select that top face. Go to Shell

16:35

and I will select 2mm, which is a little bit thicker. I do this on purpose because it's

16:42

an easier surface to see. If I go to the front view and then at the bottom left, select Section

16:51

View, we can take a look into that space. There we can see how we have also inside all the

16:59

edges. See, that's the reason why we... fillet the edges first, and then we do the shelling,

17:07

because it does create this for us in the inside with a perfect material thickness. I have here

17:16

a very sharp edge. If I would like to round this, I could also round this fillet, actually,

17:23

sorry, this edge, say by one millimeter. Let me show you something. If I go to the history

17:30

view, Here's my shelling command. Here is that fillet command. And if I press onto it, hold,

17:39

I can drag this in front of the shelling. And there everything is updated. This is a pretty

17:49

big fillet. Change this a little bit. You see everything updates for us automatically.

18:03

We can zoom out a little bit and then go to turning off the section view. And there we

18:12

are. So we have now actually the main bottle and the neck done. We don't have the threading.

18:21

The threading is something we can do actually later. It's a complicated task and this actually

18:26

only makes sense when also the cap is done. So let's go ahead and prototype the cap a little

18:32

bit. I will go to Items. Sketch 1 was the first one we created that has the basic dimension

18:43

for the cap. Currently, the cap is only a cylinder. We would like to change this, obviously, now.

18:50

So then let's go ahead and edit this cap. I

18:57

would like to have a wall thickness of 2 millimeters for this cap. And the cap actually has a lid on top that can swivel. So I need to define

19:07

now a vertical line here. So I draw one line down. I will actually also hide the geometry.

19:16

So this is easier to work. You see, I drag the end points onto the edges. Make sure this is...

19:27

vertically constrained. Then I can select these two lines and make sure this is 2 millimeters.

19:35

That's good. We have a swivel. So here's the horizontal line, and this should be around

19:49

4 millimeters. Now, when this cap rotates, onto the neck. It should kind of like seal it a

20:01

little bit. So I would like to have here a very thin horizontal kind of like cab or lid that

20:11

goes over it. And then we cut a hole into it for the fluid to come out. And I need one additional

20:19

horizontal line. And one millimeter. So if I... Zoom out a little bit and only select the elements

20:29

for the cap, main body. That's this. This is actually the space where the threading goes

20:38

in. This is a cavity. And then this is actually the part of the swivel, kind of like the button

20:46

that can rotate to open and close. And as before, We can go to the history. In this case, it is Revolution 2. There we are.

21:01

Open this, go to Edit Profiles. And now I deselect everything and then just select only what I

21:12

want. That is it. Click OK. There we are. Look, we have actually updated that geometry. So

21:22

you see, we don't really create... basic geometry and then make new ones. We actually build basic

21:29

geometry and then we can start adding more elements to it. We can close this a little bit. There

21:38

we are. We can then select this upper sketch profile and select this line and do a revolve.

21:50

That for example, is actually the part that can rotate. Just with a finger press, we move

22:00

one side down, and then the other side goes up. So the interesting element now will be

22:12

to prototype the mechanics. So this is a cylinder that sits inside an open cylinder. To rotate,

22:23

This is not necessarily going to work this well. We might maybe need to change the thickness

22:31

a little bit, or we can also round this a little bit.

22:41

This is actually going to be the rotation axis. So that dictates that from the front, when

22:50

we go back to the sketch, turn off the section cut,

22:58

right here between these two points, this straight line needs to be changed a little bit. Kind

23:04

of like it needs to be a little bit round. So we can do this very easy by turning everything

23:11

off, so it's easier to see. Then I will go to the Line Arc command and create here an arc.

23:23

And then this point, I simply drag over to this axis because that is the revolve axis. And

23:36

this tiny extra profile I created. This one, I need to add to the rotatable part for the

23:49

revolve and also remove from the housing. So you can go ahead. Here we have two movement

24:01

commands. I can press and hold and say, delete. I don't need those. And there is this Revolve

24:12

command. I can go to Profile and then I will add this one simply to it. And then from here,

24:26

I would like this tiny element to be removed. Go Edit. And... There, click on it, it will deselect everything

24:40

there. Just select this one then, and there we are.

24:50

And there you can see, we have kind of like that space for it. Really good. Beautiful.

25:03

Now there will be actually in the front an opening and also in the inside, we will shell out and

25:10

for the rotation left and right, we do need some sort of kind of like a sphere or something,

25:17

kind of like a joint. We use a sphere that's very easy to do because we added to it. And

25:25

then we can press this cap into the housing. So we can go back to our first sketch. There

25:37

we are. And I can see where this one is. And I will add this on the other side. Now you

25:49

have to be careful how much material I have, so like 2 millimeters. And I will draw a circle

25:58

roughly here. This might be height wise. Select the center point, and then I can move this out a little

26:09

bit. There we are. And then here I draw a line straight up and straight down. Make sure these

26:17

lines are horizontally, vertically constrained, 3 millimeters. That is good. And I will now

26:26

hide this body and select the sketch profile. Select the axis and hit Revolve. Now I have

26:36

actually one, kind of like one joint. This element,

26:42

I would like to mirror over to the other side. So I select the three dots, expand the menu, select Mirror, keep originals on, and select

26:53

this mirror plane. Then,

27:00

I can now show all three bodies, so the two spheres and also the cap and join them together.

27:15

I move the sketches closer to each other, so it's easier to select them all.

27:23

The inside, at this point, now we can shell out. I will do this with a 1.5 millimeter.

27:33

That's a little bit easier also to see. A more realistic value, for example, would be 1 millimeter.

27:42

And then we have these holes here, the leftovers of that shell and command. Not a big deal.

27:48

Simply select them and then we press Delete. And then that clean setup. Now, because we

27:55

added the spheres to the cap, We don't have that yet inside our housing. It's not a big

28:04

deal. We can simply remove it. So from this one, so from the housing, I would like to remove

28:14

the cap. Select Subtract. So you see I double clicked actually both bodies and then the Keep

28:22

Originals, we want to keep the removed body.

28:29

We can actually rename these parts, for example, so it makes more sense and it's easier to find.

28:36

It's a suggestion I can give you. And now there you can see how we have actually these openings.

28:42

Now, because these are spheres, you can all see it. It's going to be very easy to just simply force press that into it. Beautiful.

28:53

So we're making good progress. The next step is we can prototype how we can rotate the part

29:00

and then where the opening is. So let's see how much we even can rotate this one. When

29:07

we double click this, and because this is actually just four millimeters, the center of rotation

29:15

is right at the center there.

29:23

which means I can rotate this. So this is 15 millimeters. That's actually the max 10, 12,

29:31

no, 10 millimeters, 12 millimeters, sorry, degrees of rotation. That will work actually pretty

29:40

well. Go to the side view, select nothing, section cut. Now we can see how nicely this seals.

29:56

So 10 millimeters, sorry, degrees. Go to the History, we have no movement command because

30:04

I hit the handle button. What I will do now is I would like to take this surface and shave

30:13

off the back area at 10 degrees. Section view off. How do we do this? Super easy. Let's just

30:27

create a new add plane. You see, I have the top face selected and I just create this plane.

30:36

Don't move it, select the plane. And then I just rotate this one by 10 degrees. And with

30:43

this plane, I can actually now double select the housing cylinder. Select the plane, select

30:52

Split Body, click OK. And then this piece, which we split, I remove. There we are. This plane,

31:03

I will drag down in height. We don't really need this anymore to see, but we can understand

31:10

now when we rotate this 10 degrees, how this perfectly lines up. And because it's... the

31:17

housing is only cut at 10 degrees, I can't press kind of like the button more in. There goes

31:25

a lot more engineering into such a simple cap. I'm just simplifying the design here a little

31:33

bit. Let's undo the movement command, because I don't want this to be the timeline. So, since

31:44

we're working on

31:51

the housing here. Let's go ahead and detail this a little bit. We can give this a nice

31:59

fillet, 20 millimeters. So it's nice and big. That is good. And also here we can add a hole.

32:10

The opening will be where I'm kind of like pressing my finger. So, When I go to Select Sketch,

32:19

we're creating a sketch right onto that plane. There's a cylinder and somewhere here, I can

32:27

create a 4mm cylinder and cut through. Now this is kind of like the opening through which then

32:37

the soap will flow out. I go to a side view, select nothing, go to Section Cut, show the

32:44

bottle and there I see... Nearly there where it should be. I just need to move this a little

32:50

bit over. Not a big deal. We go to Sketch 3, select it, then we're in Edit mode, select

33:00

nothing, just select the point, and then we can drag this along the grid to the left. And

33:09

we see the update of the parametric model in real time. This is actually really nice.

33:19

This can go down. And besides the missing threading, this model right now is done. So let's take a look at

33:30

the cap. How do we do the opening? We can go to the front view, turn off section cut. Then

33:39

we make a new sketch. Actually turning section cut on now is very helpful because we see where

33:46

the top area is. And go to rectangle, tap twice, select from center. And then from along from

33:56

the Z axis, I make here rectangle 5 millimeters, horizontally, 2 millimeters up, double tap,

34:08

horizontal, vertically constraint. And then I can move this one up. Ideally, right under

34:16

the top surface. There we are. Section cut off, exit sketch, select the sketch profile, and

34:26

then we just extrude and cut through. We have

34:32

very sharp corners that doesn't look very appealing. If we would like to round this, that's very easy to do. And we just select these corners.

34:41

and round them a little bit. 0.5.

34:52

So if we show the other element, so the housing for the cap, and then double tap our element,

35:03

rotate it, and there we can see how this actually can come out. What about 12 millimeters? And

35:16

what about 13 degrees? I mean, not millimeters. Sorry for this. This actually looks pretty

35:25

good. Now this one does not really match. Again,

35:31

easy fix. We go to our history. Here's my construction

35:37

plane. There's my rotation. This was 10 degrees. And we just add three more to it. Need to figure

35:51

out the direction. So I inverted the value from positive to negative, and there now, this is

35:57

perfectly matched.

36:04

And this movement rotation command, And I hold onto it, I can suppress, then basically it's

36:09

turned off and I can unsuppress and then show it. So I don't have to all the time rotate

36:16

the slit element forward and backwards. I can simply turn on off the rotation command. In

36:26

terms of modeling, we're actually now at the stage where we can take a look at the threading.

36:36

I will create a new sketch. What is really nice is because we make a new sketch that cuts right

36:44

through this body, you see all the intersection lines and points. For example, here, there's

36:52

one and there's one. I'm drawing these lines down. And then for the moment, I'm turning

37:02

all the bodies off, so it's easier to see. Zoom in, the distance is 2mm. So I draw a horizontal

37:15

line, horizontally constraint, then a line diagonally down at a height of 2mm.

37:28

And that is the wrong direction. This one I will bring down a little bit. So you see, I'm

37:35

prototyping my threading. So this is the threading that goes onto the bottleneck. And this is

37:44

then the contact surface where it will touch with the threading of the cap. And that is

37:51

going to be there. Also two millimeters. And then I can move this whole thing up and down

38:00

to be nice and clean. We can specify this to be at 2 millimeters. There we are. So let's

38:08

make the threading for the bottleneck. Select the triangular sketch profile, select the axis,

38:16

and then we go Revolve. I'm still in section view, so turn this off. And here comes the

38:22

fun part. I'm just rotating this down. for example,

38:29

by 4. So I have a nice distance, but it's only

38:34

one turn. 360 degrees multiplied by 2 is 720. We get an error because then it would intersect.

38:46

So let's go 8 millimeters down, 720. There we are. That looks actually really nice.

38:59

Turn this sketch on again. Then we select the opposite profile, select the revolve axis,

39:06

revolve, bring this down also here by 8, 720. And there we see how this perfectly lines up.

39:23

So This is actually the threading for the bottle. Here's my bottle. I will select these two sketches

39:32

and bring them down a little bit. I can actually clean this up now and drag everything onto

39:40

one element. So it puts everything into a folder. And the start and end of this threading is

39:48

a little bit brutal. It's an easy way to fix this. Well, we can select one cap face, then

39:59

select a vertical edge, and then we simply rotate that face 50 degrees. We can do the same with

40:10

the other one. There we are. Now that already looks much, much better. Here would actually then be this inside

40:23

edge, and this goes in by 50 degrees. And here, this one to there. Beautiful. And these rotations

40:37

I did are also registered as rotation around axis features and can be adjusted. afterwards

40:45

all the time. So the reason why I actually created this is now I can select these upper edges

40:55

and very nicely round those. So there's a much better looking fillet. And then the threading

41:05

has a really nice start. I might want to do the same also. or the other edges. So I can

41:17

go to History, activate the Fillet, go Edit, and then rotate my view and add the other edges

41:32

of the other threading. Click Done. This makes really a lot of sense to work nice and clean

41:38

and group your command. There we are.

41:46

So that's ready. We will join to the bottle by simply double tapping each body, and then

41:54

select Union. And then we do

42:02

the same with the housing for the cap, Union, and there.

42:15

So there we are now. To bring everything to an end, we can add nice fillets to our specific

42:30

edges we can select. For example, all those and round those a little bit.

42:40

You have to be careful that the value you were selecting is good. There was actually a small

42:49

collide properly up here. This is nice and good. These tiny fillets are actually really nice

42:56

because they make everything look nice and soft. And also when we create visualizations, they

43:09

create very nice separations between the body parts because they create like highlights and

43:14

shadows. And simply you see where pieces are put together or not. Let's unsuppress this

43:22

one. This looks very good. So everything is now ready to go into the visualization mode.

43:28

So I go to Modeling, select Visualization. There we are. And we can now decide what... type

43:36

of material here we would like to use. We have glossy ABS, we have a matte ABS. Can drag the

43:48

matte ABS on the main body, and then the glossy onto the top. Then the glossy, I also put onto

44:00

the rotation element. You see the other material was then removed. That's a red bottle. Let's

44:08

streamline this a little bit. So the matte material, I would like to be instead of red, simply white.

44:14

So tapping onto it gives me then the ability to select a white material. And then the glossy

44:24

one, since this is going to be for a bathroom application, I give this a nice kind of like

44:31

a nice mint color. So, There we are. So we can just pick something here, there. Beautiful.

44:42

This looks good. And the white body does not separate really well from the background. That's

44:51

a very easy fix. We just go to Environment. Here we have various options of... and default

44:58

background, transparent background, a colored background. And because this is a colored background,

45:04

we can click on the cog. And then also here, for example, give this different materials.

45:12

And now you see based on how we work on, do we make actually the cap pop more? Do we make

45:20

the background pop more? We just play with the color contrast. There we are. Then We have

45:27

the ability with the rotation for the light to specify where the shadow is and also where

45:35

the highlight is. If the material for the cap, for example, is way too glossy, it's a very

45:43

easy fix. So we look down, we have, for example, the PVC or melamine. We can simply select the

45:54

glossy material. And at the bottom, we changed the color of the material, but on top you see

46:01

it says to the right of ABS, Change, select it, and then we can swap this out and select

46:10

different types of materials. This actually works really, really well. That's how easy

46:20

you can do very quickly a nice CMF study of your product. and then theme everything based

46:28

on the material, and then also the color. And then to create a nice rendering or photo of

46:34

this, all we have to do is click Capture. And that is everything. In this video, I hope you

46:41

saw how easy it is to create such an organically sculpted body, and then also how easy it is

46:46

to create the threading and prototype a mechanical cap. Have a good day.
