I would like to have access to the functions available in the ribbon when an element is selected. 
Help | Explode Imported Geometry | Autodesk
No commands related to exploding a DWG or CAD is available in the PostableCommand Enumeration and thus I cannot use the LookupPostableCommandId
A similar topic has already been posted here but it is archived.
