Warning 3DSketch25 Unable to offset one or more sketch entities. I created a 3D sketch & extracted a surface intersection. In the same sketch, I did a "convert entities" on one of the surfaces to get the edge curves & the warning above in red popped up. What does the warning mean, & how do I correct it. I'm at Michael.Piller@standardregister.com or firstname.lastname@example.org. I'm working with surface models & viewed a couple of tutorials & was looking at trying some of the techniques shown in them.
