In the attached DWG file. If you look at the 2x2 ceiling grid hatch patterns. They are somehow, someway, bound to the room space. If you attempt to do a simple move on the hatch all it does is move the hatch around inside the bound space. I have not found any way to bring up a hatch dialog box to modify the hatch. If you click on the hatch, you can see 4 odd pickboxes well outside the bound space. If you select one of them and "resize" the hatch using the pickboxes, pull it inside the bound space and the hatch is only affected inside the bound space. HOW WAS THIS CREATED and more importantly, how do you modify it? Any help is MUCH appreciated.
