>I've attached a .3dm file where I've fixed those up to be single lines and if you do a tapered extrude on this one you shouldn't see that problem anymore.

Hello Michael, what is the procedure you used to fix it?


Frenchy, I have tried to do a variable fillet as you showed but the construction line still gets in the way. Why is the construction line not interfering in your MoI? Do you have some special plugin or did you fix it somehow?




Also, is this the correct link for the Design Spark software you showed?
