Closed ksobon closed 6 years ago

I got this when I tried to query Dimensions:

hi konrad. okay... well, the process to fix it is pretty clear. determine the code snippet throwing the exception and either avoid calling it under the problematic circumstances (better) or catch the specific exception thrown (less good, also ok). can you do that and submit a pull request with the fix, please?

I got this when using the Lookup tool from Revit's UI. I am in no position to debug this particular issue. I know this doesn't exactly make it easy but that's all I got. These seem to be constraint dimensions and I am not sure why they are surfaced in my Revit model. I don't think I should be able to access them. Anyways. That's all I got. Sorry.

can you provide a minimal RVT sample? please delete absolutely everything you can except the dimension causing the error. thx!

close for now until we have a reproducible case to fix
