I am having a problem with inserting the viewport into the paper space. The project is a new house and there are about 40 pages that have viewports in them and have been working. Now I want to insert another on a new page so I go through the same process, click the named view, click go to, click close the viewport disappears. Does not add into page.
I have opened another file and check that it works and is working fine. This only is happening on the file and has only starting yesterday.
