In this video, I'd like to recreate the rear fender of this motorcycle. Let's get started and see how to do it. File, new project, and I'll open a new sketch on the front plane. From here, I want to draw a couple of construction lines. The first will start right on the X axis, go to the origin, and then go straight up the Z axis.

00:29

Hit escape twice to turn off the sketch tools and then select everything and change them into construction lines. Because of the shape of the fender, I'm going to want to use a revolve feature and the cross-section of this revolve feature will be mostly drawn with straight lines. So let's start with sketching a line straight across.

00:57

and then an angled line and another angled line on the other end. And then let's make an arc. I use the A key to switch over to an arc and there's our cross-section. Now we need to fiddle with this a little bit to make it correct. So I'll drag this endpoint onto the origin and lock it. Select the endpoint of the line and

01:26

this horizontal line and use the midpoint constraint. Also make sure that this line has a horizontal relationship and then I want to select these two angled lines.

01:46

click the Symmetry tool and click the Vertical Construction Line. So now if I drag anything, it all remains symmetrical. I can make a vertical distance for the angled sides. So I'll click the line and select the point. This will be one inch or 25 millimeters if you're going that direction. The width will be 10. This angle, click and Shift.

02:16

will be 80 degrees and the radius will set to 20. All that's left is this radial dimension and I'll set this also to 11 inches. Now from here I'm going to want to use a revolve which I'll have to get out of the sketch for and go to tools, revolve. I could also use a V hotkey for this.

02:45

I'm going to follow the tool tips in the revolve prompt up here. So select faces or sketch fillings. That means inside here. And then select an axis to revolve around. And that means here. So I'm going to reorient slightly. I can click this point up here to get an isometric. I don't want 360 degrees. I might want say 110 degrees. Let's make that go a little bit further.

03:13

and I'll grab the arrow this time to do it. Let's make it go 120 degrees and click done. And now for my second revolve, I want to use a sketch that's similar to this. In fact, it'll use most of it. So I'll open a sketch again on the front plane and notice that it shows me the sketch that I used before. But what I want to use is a small section of this.

03:42

So I'm gonna use the arc.

03:46

Click, click, and.

03:52

We're going to use 80 for the radius. So that gives a flatter profile.

04:00

exit to sketch because I can use this sub part of this sketch to revolve. Tools, revolve, select in this area and click the axis to revolve around. Control 1 for an isometric view. Let's use the arrow.

04:23

to visually get what we want to use for this revolve. Now we're going to cut some of these back. So we're going to create more of this than we need. Let's select on done. This tutorial will continue in part two, where we'll talk about construction geometry, feature options, and how to use bodies in Shapr3D.
