Connecting sketches using coincidence constraints

00:00

Shapr3D has a very intuitive sketch guide system, which automatically adds constraints to your sketches while drawing them, making sketching in Shapr3D faster and more intuitive. Let me show some examples. In a new design file, let's go to the front view. In snapping, we turn off the grid option, so we can better see how the sketch guidelines will work. In the toolbar, select Sketch.

And with the line command, somewhere draw a line at any angle. Notice also how we do not snap to the grid because it's turned off. Then we click and move the next line at any other angle. Now pay attention to what happens when I move this endpoint. So it draws a line that follows the direction of the first line. You will see this violet line. That is the sketch guideline.

01:00

We also have the ability to draw this horizontal, vertical, and also perpendicular to the first edge. I would like to draw this line horizontal. So I make sure that I move the point horizontally away. It will then snap to this guideline. Then to draw straight down, I just make sure I'm very close to the...

down direction. Notice also how we start seeing all these other intersections. So now I'm drawing a vertical line down that intersects with a perpendicular guideline from the first line. I would like to maybe find this midpoint line. You see how I can find this here. And to continue.

01:56

I would like to draw this line vertically straight down, but stop where the first point is. Then I click and I can go over. And you also see here all these instant snap points. We can click, right click, drop the line tool. And we drew a shape where we have two horizontal and one vertical line without using the grid or any sketch constraints.

02:30

I have everything removed. Let's draw one line at any angle again, right click, and then I draw another line at any angle and right click, right click, and drop the line tool. What I now would like to do is move this point at a guideline of this line. So I can select this point, then I move this onto the line or the endpoint that basically now tells the system,

03:00

to memorize and then project this guideline to which if I now release my mouse, I can snap. You see, there is now a coincident constraint. When I click somewhere else and then hover over this endpoint, you see this endpoint has a constraint and there is a dashed violet line. What is really interesting now is that this line and this endpoint, they are in a relationship.

03:29

So this means when I select this endpoint and move it, this line will rotate. That's actually really nice. When I select the other endpoint, when with that rotate that line, you see how I'm dragging that line.

03:50

And this can be very useful when you want to create relationships between individual sketch elements without having them physically be connected.

04:04

We can also create this coincident constraint relationship between a line and an arc. So with the arc command selected, let's draw somewhere an open arc like this, and then we call the line command. And now I would like to draw a line that fits somewhere somewhat horizontally inside the circular parameter this arc represents. To generate this curved guideline, I move my cursor

onto the arc. And then you see here is the guideline. I can click, go to the other side and click, right click, right click, drop the line tool. And as you can see now, when I move my mouse onto the end points, I see that there is a coincident constraint and here's also the guideline. So when I move this point or this point of the line, the arc moves with it.

05:03

If I select the arc and move it, the line then moves with it.
