Placing Model Space Views on a sheet has become extremely slow in regards to a specific view and sheet file. If we do this with a different file, it works just fine. However, these files (one is an interior elevation view file with a lot of separate model space views and the other is a corresponding blank sheet) seem to take about 5 minutes just to get the insert viewport dialog to show up. Any suggestions. There are quite a few model space views in the view file (We have them broken down by areas and this area has two locker rooms and three toilet rooms that we are elevating). I would hate to create a view file of each room.
