Keep Background: If ON, retrieves backgrounds contained in a wire file. The initial default is ON.
Keep Construction Options: If ON, a prompt will appear asking the user if they would like to Accept the construction options contained in wire file. The initial default is ON.
Keep Render Globals: If ON, brings in the render globals set for the wire file into the system, overriding the current settings.

To set render globals, use Render > Globals (see the Rendering book).

Keep Bookmarks: If ON, bookmarks are imported as before. If OFF, the bookmarks are not imported. This helps avoid the proliferation of bookmarks that can occur when importing several files.
