I need some advice on how to accomplish a task in rhino.
If I have a mesh model of a straight union that would be used to join two pieces of PVC pipe, and I want to decrease the wall thickness of the pipe without decreasing its inner diameter, how could I do so?
It’s like trying to shrink the thickness of a doughnut without shrinking its hole.
I thought about scale 2D, using the center of the pipe as the origin but that shrinks the inner diameter, not just the wall thickness.
Please tell me how you would do it?
Thanks,
Don
