Is there any way to get GetSectionProperties2 for face of part if I get IModelDoc2 from IComponent in assembly? Ie I do not want to open individually parts.

I also tried to use EditPart2, but method GetSectionProperties2 allways throw error to me " access violation".

I also tried use "Select" for entity

IEntity selectedEntity = (IEntity)myFace;
 returnValue = selectedEntity.Select(false); //allways false
