Hey friends,

I want to create a driving sketch for a foldable table. I would like to limit the movement of the table and foot to 90°. In the video I attached you can see the basic principle. How can I restrict the possible movement of one point to my quarter circle? When I exit the boundaries, it just elongates the circle line … And when it hits a 90°/0° point, it snaps to constraints … Difficult task. Looking forward to your suggestions! Thanks 🙂

Shapr does not have that kind of constraint unless someone knows a way with variables.

You can use control spline for that. Not perfect but work.

At some point the leg part snaps to the surface part and won’t split again …

BTW, why is the video linked externally? Up above it worked like a charm …

Looks like wrong constraints somewhere…
