I select object in SE assembly by creating command using Application.CreateCommand method. I using mouse settings:

Command.Mouse.WindowTypes = 1; //only graphic window   
Command.Mouse.EnabledDrag = false;
Command.Mouse.EnabledMove = true;
Command.Mouse.InterDocumentLocate = true;
Command.Mouse.LocateMode = (int)SolidEdgeConstants.seLocateModes.seLocateQuickPick;
Command.Mouse.ClearLocateFilter();
Command.Mouse.AddToLocateFilter((int)SolidEdgeConstants.seLocateFilterConstants.seLocatePart); //occurrence and suboccurrence objects, if i undestand it well

How to detect selected object type?

When i stop mouse moving above subassembly and wait, until appears icon QuickPick, then i click rigt mouse button and i select suboccurrence from list, this selected object is not occurrence nor suboccurrence.

How to detect type of selected object, and how to select suboccurrence in SE assembly? How to select subassembly occurrence ?

Thanks.

Hi Juraj,

you can check the type of the seleced objects in the SelectSet (you can select the objects with SelectSet.Add too) . All the items are the objects. If you select an occurrence (first level of a Topassembly) is a occurrence as type. If you select a suboccurrence with a mouse is a reference as type, the reference.object.type gives you the type (occurrence object, not suboccurrence object). If you select the object "occurrence" in subassembly, than is this an object of the subassembly and "not" from the Topasssembly. You should select a reference or a suboccurrence, and an occurrence only in first level of Topassembly.
