MDI and sds_entmake()

Hello,I would like to get information from the current drawing and create some new entities on a new "to be created" drawing.Questions:1)How to create a new drawing without use the "NEW" command?2)How to make a sds_entmake() on this new drawing? Is there a way to make it active?I have used an undocumented MDI samples from ITC website but I don't know how to use the sds_mdi_activate() sample function...Any tip would be nice!Regards,Fernando.
