Options to try:
1) Use disk utility to repair permissions
2) Do a new and reset in AC to see if there is a problem object or setting
3) If it is a project that is giving you problems, it might be a problem library part or slab/roof/terrain that have invalid holes
The last time I had this happen to me was after drawing a slab and using the magic wand to remover a portion of it. For some reason AC then crashed either when building an elevation or when closing. This was in AC8.1
