Visibility in Group/Component editing
-
I have two tools that are using model.raytest(ray) and have bumped into a problem with DrawingElement visibility in Group/Component editing mode.
All DrawingElement methods dealing with visibility - visible? and hidden? they refer to a state of the element in a model, but are completely unaware of a visibility of the element on a screen (OpenGL 3D space to be "precise").
Group/Component editing options allow to Hide elements from a view, but how can we check it from Ruby?! Is there a way to figure out whether such an entity is really "visible on a screen".

I have found Model.active_path from SU 7.0+. It looks I will have to compare an oldest entity in a family I get from the raytest with oldest entity from the active_path...
Are there users still using SU6?

The only one I could think of is Pilou

Use the second item in the returned array, with is the instance path array. Traverse through this and check if any of these entities are hidden on on a hidden layer. Works in all versions of SU.

Thomas, it is not what I have been looking for. I know that this works, but I doesn't give you an info on whether an object is hidden by 'Group/Component editing' option from the 'Window/Model Info/Components'.
The Model.active_path solution works very well. I have to obviously traverse whole active_path and compare each element with the second element of rayrest return.

Ah, ok now I understand. Yes, then Model.active_path is what you need. And checking if Hide Rest of Model or Hide Similar Components is enabled.
