Per ViewPort Visibility not deleting properly

Rhino Developer
1

Hi,

I noticed that when I do the following:

  • 1 draw a detailview
  • 2 swich off per viewport visibility for a layer in that detailview
  • 3 delete the detailview

The property “HasPerViewportSettings” of the layer is still set to true, even after re-opening the document.
The property “HasPerViewportSettings” is set back to false only if I run the rhinocommand method " DeletePerViewportVisible"

This is an issue when dealing with files that have many layers and many viewports, because it does slow down significantly the edition of PerViewportSettings.

I wonder why rhino does not automatically “DeletePerViewportVisible” whenever a detailview is deleted by a user.
@Rhino can you fix it or explain me where I am wrong?

Thanks!
