Hi, 

I am working on a file (in the PLM) and trying to select the point on helix to create a plane for thread profile. for some reason I am not able to pick the point on helix.  For a new part created on local drive, I am able to do it.

My question:

1. how can select the point on helix.
2. IF the issue is with the file then is there any setting that I can change to select the point?
