The Studio for Progressive Modelling (SPM) has started development of a couple custom GH components:
This one produces a principal curvature line emanating from a point on a surface – lines that are useful for constructing panelizations of freeform surfaces consisting entirely of planar quadrilaterals and prismatic structural members. It has been proven that surfaces with these characteristics are significantly more cost effective. However, the aesthetics of these panelization schemes are often quite pronouced, and so this component is a light weight solution that allows designers to see what kind of principal curvature mesh a given surface might suggest.
See Evolute and Daniel Piker’s work in this area for other aspects of panelization with planar elements. I find the latter approach very interesting, as it does not depend on a setting out the curvature lines as an initial guess – even though these are fundamental to the construction. Or are they?
We’re also working on some Rhino to Revit/SAP links, and hope to post some information on those soon.
