Using Rhino 6, I have a polysurface. Is there a way to draw contour curve(s) based on the direction? For example, I’d like to draw a line at the point where the surface normal is 45deg.
I can used the direction command and hover and see the angles and place points and try to connect lines, but I want to know if there is a smoother way to do it
Alternatively, I also have a mesh version, if there is a way to select facets based on direction, that could work as well
you can project the line on the surface and then use the _Fin command to extrude it tangent or normal to the surface, is that what you want?
Hello - use the
DraftAngleAngleAnalysis to visualize the line or curve:
testSilhouette to get a curve - this is a test command and not very friendly, UI wise, and not supported but will allow you to set a draft angle at the command line if you do not pre-select the object.
draftangleanalysis does visualize it, however I want to create a curve that I can split on.
I tried Testsilhouette but I get “111 ON_SIL_EVENT returned”
