Hello, I’ve been writing a dynamo script that converts buildings from the CityGML-format to 3d-solids. The walls of my buildings are defined by points that create a surface. I extract the points that form a surface and try to create a surface using “Surface.ByPerimeterPoints”. The script processes…

I recommend leaving the geometry scaling as you risk losing accuracy of shapes. Instead pull the points closer to the origin and see if that clears the issue when making the geometry. Instead try this: Starting with the list of lists of points Take the first point out of each sublist using a List…

@pumpaij

these are the input… …which error do you have?

could be you have to extract the right points
