Selecting edges and vertices of a Solid3D entity in Eyeshot 11

Question

I have a Solid3D object inside a block and need to select its edges.

I tried:

viewport.SelectionFilterMode = selectionFilterType.Edge; 
viewport.ActionMode = actionType.SelectByPick;

As the block is treated as a single object, doing so would select the whole Solid3D object.

Could you suggest me a solution that I could use to get around this?

Answer 1

You should set viewportLayout.AssemblySelectionMode to assemblySelectionType.Leaf:

viewportLayout.AssemblySelectionMode = ViewportLayout.assemblySelectionType.Leaf;

and viewportLayout.SelectionFilterMode to selectionFilterType.Edge:

viewportLayout.SelectionFilterMode = selectionFilterType.Edge;

Answer 2

You can set the BlockReference as current.

viewportLayout.Entities.SetCurrent(myBlockRef)
