SubD Ring and Loop Selection is Really Bad

Rhino SubD

Specifically talking about edges, I struggled daily and loose a lot of time selecting my edges one by one because the tool is just not smart enough.

I often let these go even though my mind tells me it should be possible to code this, but I am not a developer so I let it go.

It really grind my gears when I realize other software does it ok and confirms to me it could be this way also in Rhino.

This was done with only 4 clicks in C4D. Notice how the holes and naked edges do not break the continuity of the rings and loops.

Tried filter selection? I find it quite useful when I made the skull

Hi, not sure what you are trying to tell me here.

The ring and loop selection just does not select the way it should.

Hi Shynn - The current edge loop selection is indeed odd, when there’s an open face involved. In the example you posted right above, I’m not sure the correct answer is to select the open edge as part of that loop selection, however, it definitely should not select the “vertical” edges, when sub-object selecting the circular loop. I’ve logged it ( RH-84736).

Thank you Vanessa.

I think most often than not you want selection to keep the rings and loops despite open faces.

For instance here, this is happening because the selection is not differentiating between loop and ring.

Also here you want to select the entire vertical edges despite open faces.

Thanks @ShynnSup ! That makes sense. I’ve added your comments to the bug report.
