I’m getting an error messgae when trying to create a floor:
Warning: Floor.ByOutlineTypeAndLevel operation failed. The multiplicities of other interior knots must be at most degree - 2. Parameter name: knots
The problem is the first nurbs curve. It was originally an arc which was offset (curve.extrude > surface.thicken) , but somehow Dynamo turns this into a nurbs curve and it subsequently fails. I can’t even create a model curve from it. Any ideas how to fix this.
