Segment Editor: Draw Tube - it makes octagonal prisms instead of smooth cylinders

Support
1

I am using the draw tube feature in the segment editor. It is great, except that it is drawing octagonal prisms instead of cylinders/tubes. This is much more apparent when the radius is increased to above 10. Can the number of sides of the polygon be increased to make smoother tubes?

I am running the current Slicer version 5.8.1 on Windows

Here is the source:

You should be able to change the resolution to any you want (only limited by segmentation geometry). Currently the resolution is hard-coded to 8 sides for the tube

Thanks! I will give this a try.
