Hi there! I'm going trough the basics of Houdini and I was trying to create a "tool" to create tube/tube sections like those you see in TV news intros.
The thing that is hitting me is that I want to select only the "contour" edges and bevel those without influencing the division ones which i want to be able to control separately!

How can I do this?
Thanks in advance.

This is what I have:




This is what I want.

Hello,

There is an 'ignore flat edge' option in the exclusions section of the edge bevel.
For a 10 sections tube, you need to set an angle slightly higher than 360/10.

Depending how you build your geo, there is probably a way to tag those edges upstream in the process, making the process more reliable than based on an angle. (.hip attached)

Thank you so much Pascal. I was able to figure out through your file the setting I was missing and that was "Include Only Elements on the Boundary" in the group promote note! Problem solved Thanks a lot!
