Autodesk architectural desktop 2012. Never had this problem previously. Have (2) layouts in a drawing file. I want to copy and paste viewports and titles from one layout to the other layout. Copy function appears to work, but paste does not. I've used a common base point (the origin). No layers are locked. I've zoomed extents and regenerated. I've rebooted AutoCad. Still can't copy/paste from one layout to another in the same drawing file. I can copy and paste to a different drawing file. So I will copy paste to new file, and do a save as, to overwrite old file for now. Any ideas on why the copy/paste between layout in the same drawing isn't available?
