Error - The multiplicities of other interior knots must be at most degree - 2

Hi

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.

Hello @Paul_Wintour …probably something could help…

This should do the trick: Dynamo Dictionary
