Now plant 3D user have opportunity to validate, for example, Pipe Line Group, Hand Valves, Equipment, ect. by checking the box in the special section (pic. 1). It's good.
For Pipe Line Segments subclasses user can't check this box, because there is no any boxes (look at the pic. 2), so user can't validate this P&ID subclasses for any property value mismatches, for example, for Size, Insulation Thickness, Material, ect. It's no good.
So my Idea is to find any way to validate for property value mismatches for Pipe Line Segments subclasses.
