ReMark Posted October 8, 2019 Share Posted October 8, 2019 This would be a good time to learn 3D. Did you know that 2D views can be generated from a 3D model? Quote Link to comment Share on other sites More sharing options...

CyberAngel Posted October 8, 2019 Share Posted October 8, 2019 I was able to model the intersection by extruding both of the ellipses, making a copy in place of the larger one, and then subtracting it from the smaller one. The trimmed ellipse and the copy remain. 1 Quote Link to comment Share on other sites More sharing options...
