I keep getting this error on when I try to draw the alignment line on Level 1.

How to proceed?

Hi @apoorvapradhan, what version of the Revit plugin are you using? Or are you trying the online version of the editor?

Are you using the sample models that we shared?

If you are trying the online version, make sure to either user Chrome or Edge. I tested several models, and I was not able to recreate the issue.


If you are using it from inside Revit and with a certain model, can you download the model and share it with us?
