I am trying to learn modeling with Rhino and Grasshopper with URBANopt SDK. I was trying to do just one building first. I am stuck trying to convert DF model to GeoJSON, and need your help to figure out what happened exactly. ERROR: 1. Solution exception:index out of range: 0
Please try to help me. I tried to attach the gh file but the website won’t allow as I am a new user.
