you need to do this following every single geometry action

I have discovered that the only way to be sure of safely building something in model-it, is to do this after *every single* geometry operation. Yes, it is time-consuming, but the alternative is to lose your work and/or have geometry errors later on which can take hours to fix and involve rebuilding much of the model:

1. Quickly hit save in case the VE crashes, as it often does.
2. Rebuild adjacencies
3. Run a model report.

It is necessary to do 2) before 3) because sometimes geometry errors are only revealed after you've rebuilt the adjacencies - you can be merrily building your model, checking the geometry as you go, thinking all is fine (cos the model report says so), then later on you rebuild the adjacencies and suddenly a load of geometry errors pop up out of the blue.
