Removing profile PVIs not working

[JamesMaeding]

I am trying to clear out all pvis in a profile, code is:

while (profUse.PVIs.Count > 0) {
  profUse.PVIs.RemoveAt(profUse.PVIs.Count - 1);
}

 seems like its the right approach, you cannot set the pvis collection to a new collection.

It catches every time though, does not matter how many pvis in the profile.

Seems I need some education on what you are alowed to do with pvi collections.

thx

I think that you cannot delete the first or last PVI, as a profile must contain at least 2. Not in a position to do any checking right now, though.

seems my old com code just deleted and added back to avoid the Autodesk imposed rules.

That worked with .net too.
