This is a question about TUBEA.

It was done with TUBEA.
As the height changes, the thickness changes.
I want the thickness to be the same.
Is it possible?

The thickness went from 150mm to 100mm and back to 150mm.

TUBEA 2, 10, 1 + 2 + 16 + 32, 0 , HBottom, 0, um_ThkWall, HBottom, 0, Wid , -100, 0, Wid , -0.1, 0, Wid , 0, 0, Wid , um_Length_Start , um_Height_Land, Wid , um_Length_Start+WidL, um_Height_Land, -Wid , um_Length_Start+WidL, um_Height_Land, -Wid , um_Length_Start , um_Height_Land, -Wid , um_Length_Start-um_Length_End, ZZYZX, -Wid , um_Length_Start-um_Length_End-0.1, ZZYZX, -Wid , um_Length_Start-100, ZZYZX

Maybe You can use TUBE and cut it with a TubeA by solid element operations.

Tube keeps it´s profile the same.

The tube path should be flat.

The TubeA should be thick enough so that the minimum thickness is present everywhere.

The code can be like this:

Group "TubeA" ---- endgroup Group "Tube" ---- endgroup placegroup isectgroup ("Tube", "TubeA") killgroup "Tube" killgroup "TubeA"

Sweepgroup produces good results.
