Rooms Move When Drawing is Opened

Posted on November 1st, 2010. Last updated on March 12th, 2024.

Problem: When you open a drawing, the room outlines move to a new location. The rooms are all in the same relative location to each other but have all shifted or rotated by the same amount.

Cause: This typically happens when an alignment point has been modified, and the drawing later crashes without saving. When the alignment point is modified, the locations of the rooms in the database are updated. Crashing without saving causes the alignment point to lose the changes made to it. When the drawing is reopened, the drawings appear to be in the wrong location relative to the alignment point and are updated.

Solution: The solution to this problem is the same as the cause: modify the alignment point, then intentionally close the drawing without saving. Making changes without saving should not be done the vast majority of the time, but it is necessary here.

If the rooms all appear to have been rotated about the alignment point, you need to rotate the alignment point when you modify it. If the rooms all appear to have been shifted, you need to move the alignment point when you modify it. You need to move or rotate the alignment point in the opposite direction you want the rooms to move. If you aren’t sure what to do, try making a change and seeing what happens. If it turns out to be wrong, you can then make the change the other way. (Rotate clockwise, then rotate counterclockwise if that did not fix it; move left, then move right if that did not fix it).

Make sure you save the drawing before modifying the alignment point. After you modify the alignment point, close the drawing and do not save it. When you reopen the drawing, the rooms will move.

Once the rooms are in the correct location, we recommend you run the Coordinate Drawings and Database command on this drawing to fix any other errors that may have been caused by the original crash.
