1.2

Removes all erased entities or unused definitions from the drawing database.

extern "C" void WINAPI VCPackData(WORLDHANDLE hW);

procedure VCPackData(hW: Longint); stdcall;

Sub PackData(ByVal hW As Long)

hW - the Visual CADD™ worldhandle of the drawing to remove erased entities.

Simply executes the command as if the user had selected it from the menu. Any entities erased or marked as erased by a modify command remains in the drawing to enable the undo and redo commands. While maintaining these can get quite cumbersome with limited memory resources, using pack data will remove these erased entities from the database and free up the memory taken by them. Immediately after a pack data, undo will have nothing to undo.
