"Transform failed because of constraint" -- which constraint?

Need help? We are here.

This is a help and a feature request.

When a move/rotate (and probably other transforms as well) fail because some of the constraints couldn’t be satisfied, Shapr3D gives an error “Transform failed because sketch constraints couldn’t be solved”, but it doesn’t give any hints on which constraints those are, so often I have no idea what to remove or adjust.

In the screenshot below, I have these constraints:

  • The circle mid point and radius is fixed.
  • The two lines (10 cm each) have fixed lengths, and the angle between the end points is 180 degrees.

Given these, I don’t know why I’m unable to rotate the selected lines more than some amount. I would expect the line rotate around the mid point freely, 360 degrees. But apparently there’s some constraint that can’t be solved as I rotate, and Shapr3D doesn’t give any hints on which constraints those may be.

Hello keeb123,

You may wish to try copy, and then move.

I’ve encountered the same problem with the two dimensional polygon that I’m just trying to move along one axis and it keeps giving me this error over and over again. However, when I try and copy, I can’t move it far enough and what ends up happening is the copy overlaps the original and now I’ve got a screwed up geometry. Please help!

I tried several other attempts to remedy this error, but everyone of them resulted in the same. I finally gave and erased all the visible constraints on my 2D polygon and lo and behold this worked!!!
I don’t which of the 8 or so constraints was the cause, I just know the the move command worked as expected and all was well again!

Erase all your constraints and then try again
