I’m stuck on this problem, something went wrong for some resons, Could you help me see what i did wrong?

Why do the semicircles at both ends change shape when I shorten the two lines? How can I shorten the lines while keeping the semicircles at both ends unchanged?

Question 1:

Question 2:

When I tried to shorten the distance, it turned out like this.

In the bottom example try selecting both lines and using the = constraint. Shorten one shortens the other too. Try that.

Inthe top example you make circle with a set diameter. Changing the line width doesn’t change that diameter. Try this: In history try to change the circle diameter to match the width you want to change.

Thanks for reply

I referred to this Sharp 3D tutorial video, starting from 14:09. You can take a look; I followed along, but I still couldn’t get it to work.

May be the vid is edited, you can see the tangent badgets there…(between the lines and the part of the circle)

At 14:43 look at the constraints

Thanks for your reply!!

I’m sorry, this is my first time dealing with 3D, and I still don’t know how to operate it. Where can I find the ‘Constraint \> Tangent’ option in the interface?

Could you please do a screen recording for me to show me? 🙏

When you are making things like that loop, you drew the lines and the circles. Select the lines and circles and the tangent function should show up on the right side under constraints.

Try this: Make a circle anywhere. Attach a line to it like a lollipop. Select the line and the circle and set the tangent constraint and see what happens.

constraints are an important friend. You can lock lines and points so they won’t move when you move another attached element like a line or arc. You can make lines stay equal lengths to each other or parallel to each other. And many more cool tricks to add your sketching,

On the opposite side with the drawing tools…

A carefully planed sketch is essential to a good design process.
