Hello Guys.
I am having trouble with a couple of viewports, I have the floor plans made into a viewport on my site plan, and when I am looking at the site plan, the floor plans keep disappearing when I zoom, and I can see them flash when I zoom in or out but they are not staying visible. I have checked all the class settings to make sure there is nothing odd going on there, and all the correct classes are turned on. This is happening on the design layer that my site plan is drawn on, and also on the sheet layer of the site plan.
This is the way I have always done the site plans and I have never had this issue before. Has anyone else come across this sort of thing happening and have any ideas of what to do about it?
Thanks.
