How can a Softdesk project be detached from a drawing?
Go to Paper Space. Then, go to AEC -> Build Selection Set Check the Block box, and to the right of that check box, type in ADCADD_ZZ as the current selection criteria. Click on Build Selection, then Apply. Next, type the ERASE command, then P at the select objects prompt (previous selection set), and hit enter. Go back to model space, quit, save changes, reenter Softdesk, reopen the drawing, and reinitialize. You should be prompted to attach a new project.
