I have point-cloud data for which I used the Patch command to generate a wavy NURBS surface.
I need to make 2D measurements of cross-sections of the surface (plane/section view). I need to align my viewing-plane so that I can see a single point of highest curvature and have the plane aligned parallel to the point of greatest curvature. I’ve uploaded a cartoon sketch that illustrates my goal. Because my surface is a dome with one axis longer than the other, the min. and max. curvature are not always orthogonal with the U and V of my NURBS surface in rhino. Thanks in advance.
hi, i hope this helps and that i understood you correct.
CurvatureAnalysis
and ClippingPlane
may help to find your points, after you have evaluated those use section
and draw a line through the 2 points followed by the command close
to close the curve followed by PlanarSrf
. now call either OrientCameraToSrf
on this new section surface with the option Set Construction Plane
. or you use CPlane
with option Surface
which will only set the Cplane of course.
Thanks, encephalon. This was very helpful.
