I keep getting the following error _"Warning: Floor.ByOutlineTypeAndLevel operation failed. _ The curves do not form a closed contiguous loop. Parameter name: curve" however according to the image below the curve is closed… [image] does anyone know why this is happening?

Hey @Tom_Denby :slight_smile: Im not sure why it isnt picking up the polycurve as closed. Could be to do with the number of segments maybe. But you can just add on the “Polycurve.CloseWithLine” node to the output of the polycurve and carry on from there: [image]
