Hi there,
could anyone give a tip what is the best tool to enlarge a circle?
Let’s say f.e. if I need to model a kind of “washer” or give thickness to a cylinder/ pipe?
The extruding tool doesn’t seem to be useful!?
Thanks ๐

Hi Adriano,
Iยดm afraid you are right. Extrusions are defined linearly and in whatever combinations of x, y and z directions only. What would be needed here is to have a special kind of “offsetextrusion” commnad where one can select a curved edge and make an offset to extrude it (create faces) at 90ยฐ (spatial 3D) from original curved edge.
What I think you could do instead is to create another cylinder with same center and a defined radius to account for the thickness and then close the edges to create the solid pipe. More man hours of tedious clicking, but it will work.
Regards,
Sergio.

Hi Sergio,
Thanks for yr comments.
Yes, I was afraid that building another cylinder around ๐ is the only main option left.
