Component Wall from NURBS Surface

Recommended Posts



Here is a script that converts a NURBS surface to a wall with components that can be exported to IFC. The wall is an Auto Hybrid object made up of 3D Solids that match the thicknesses and attributes of the components of a referenced wall style. CWS_1212_IFC.vwx


A couple caveats: Make sure that wall style names do not  have a single or double quotation symbol in the name - it will get misinterpreted by the String Node. Also, if your base surface is an Interpolated Surface, use the tool in the 3D Power Pack - Rebuild NURBS... - to convert it to a standard NURBS surface.

@sbarrettThanks for this. Its pretty impressive and can be used in many great ways. Grassy mounds comes to mind.


Also I love the way you have controlled the classes and wall styles, good example to all.

As its not an actual wall the texture is defined in the other and not the wall or roof section of the Edit Class. OIP.  I think.

Cool! - this should in theory work with roof and slab styles as well
