Rhino Crash Course: Extracting Linework from 3D Models

Описание: Some fundamentals of grabbing curves, intersections, boundaries, and sections from 3D geometries in Rhino. Some of the gems in here are:
-DupEdge (extracts a curve at a surface edge)
-DupBorder (extracts all the curves around the perimeter of a surface)
-ExtractIsocurve (extracts individual isocurves from anywhere on a surface)
-Section (extracts all the curves where a 3D model intersects with a vertical plane)
-Make2D (makes a 2D drawing of whatever you're looking at, basically, and why it sometimes doesn't work).
-Intersect (extracts new curves where surfaces intersect each other)
-IntersectTwoSets (extracts new curves where two groups of objects intersect)
-ExtractWireframe, with and without Isocurves! (extracts all the edges and visible isocurves from a 3D model)
-ExtractClippingSections (extracts the clipping plane intersections as curves)
-ExtractClippingSlices (extracts the clipping plane intersections as surfaces)
-CurveBoolean (like Illustrator's Shape Builder tool, but for Rhino!)
-Trim (the trim you're thinking of)
-Contour (extracts curves at parallel “slices” through an object at a specified interval) and direction
