Hi, I think this should help:

> With latest “curve drawing on surface” feature (to be announced next week, but already available in latest Slicer Preview Release) you can extract one side of a surface very easily: Draw a closed curve on the surface Make the curve snap to surface (enable Markups module / Curve settings / Curve type → shortest distance on surface, model node → model node that you would like to cut) Copy-paste this code snippet to the Python console # Get input data curveNode = getNode('C') modelNode = getNode…
