Copied Components Disappearing

A simple problem.

Using ProStructures V8i (SELECT series 6 R2 for AutoCAD) - Verision 08.11.11.207 from Jul112018

Autodesk AutoCAD 2016, Product Version M.151.0.0 AutoCAD 2016.0.11

  • I am using any 3D visual style in AutoCAD 2016 such as "Shaded with edges" or "3dWireframe"
  • I have created a ProSteel 3D model.
  • When I copy a component using the native AutoCAD copy command the new object disappears. 
  • When I switch over to the visual style "2D Wireframe" the component is there.
  • When I switch back to any 3D visual style it is once again missing and cannot be selected.
  • This also true when I use the ProSteel Divide command. 
  • This also true when I use the ProSteel PS_Copy command.
