When I wrap an ellipse round a cylinder why does it not stay the same size as sketched?
an ellipse with a length of 190mm wrapped round a cylinder of 220mm dia changes to an ellipse with a length of 179.99mm
What am I missing here? I want it to be 190mm long that's why I sketched it at 190mm long.
Hi Al,
It is hard to tell what might be going wrong from your pictures, so attach a part if you can't figure it out. Attached is a part I made and it works perfectly. If you change the dimension on the ellipse, you will see the reference dimension that I added by putting a sketch across the wrapped ellipse updates correctly.
I hope this helps,
Jim
