Jake and Dan with a new post on an OTL for Side Effects Houdini they are sharing. A custom CurveOffset SOP Asset for Houdini that uses elimination of intersections rather than position clamping. Download the CurveOffest SOP Asset for Houdini here.

This OTL for Side Effects Houdini works similar to the Extrude node: it takes a NURBS- or poly-curve as input and offsets it to get either a growing or shrinking effect. The big difference to extruding with a thickness offset is that it uses elimination of intersections rather than position-clamping.
