Drawings that have xrefs that are not shown (unloaded)

Summary

There are some drawings in other cad software that have external reference drawings that are not shown (unloaded). Is it possible to add this in VDF ?

Solution

In version 6020 a new property IsXrefUnloaded of vdBlock was added.

Default value for IsXrefUnloaded  is false.

Set it to true in order to unload the ExternalReference document and make it invisible.

Also a new CommandOption argument "U" was added in CommandAction.CmdXref method

example :

  CommandAction.CmdXref("U","Xref1.dwg",null,null,null,0);  //Unload the previous attatched "Xref1.dwg" and make it invisible.

call

 CommandAction.CmdXref("R","Xref1.dwg",null,null,null,0); // to reload the drawing and make it visible

Also a new button "Unload" was added in frmXrefManager dialog resources of vdFormsRes project
