I have created a triangle with 3 sides: 65", 68" and 72". I have extruded the triangle to 6 inches. No problem here. I now need to angle each side by 6 degrees inward. I have tried many ways including negative extruding an edge but without success. Please enlighten me as to how to do this.

How about subtraction?

In the Extrude tool, there is a Draft Angle input, try entering 6 or -6 degrees there and it should be automatic during the extrude. Hope this helps… Good luck!

Best,
