This picture is very interesting. It uses the loft function, but the guide line of R90 can’t be the same as the position shown in the diagram. Ask for help

Hi Jean-Philippe2

Something went wrong for some resons, Could you help me see what i did wrong?

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? 🙏

Yes JST is right.  
Trim the lines (circle and rectangle)  
Use Contraint \> Tangent  
Change the dimensions of the sketch (width of the rectangle)  
See screenshot.
