A common operation in any Rhino for Mac workflow is extruding two-dimensional curves into 3D surfaces. In this video, learn how to use Rhino’s extrude commands to turn curves into surfaces. 09 - Creating Surfaces, Solid, Extrude Curve Basics. Rhinoceros Freetrial . Previous Video Next Video
NURBS curves and surfaces are generalizations of both B-splines and Bézier curves and surfaces, the primary difference being the weighting of the control points, which makes NURBS curves rational. ( Non-rational , aka simple , B-splines are a special case/subset of rational B-splines, where each control point is a regular non-homogenous ... I developed a grasshopper logarithm that creates a model in Rhino with all the building height data provided by Digimap in a model that has true NURB surfaces and few isocurves. No need to calculate the height of buildings anymore and to extrude them like I did when I built a previous model in SketchUp and would have to do it again in Rhino.
Surfaces: from 3 or 4 points, from 3 or 4 curves, from planar curves, from network of curves, rectangle, deformable plane, extrude, ribbon, rule, loft with tangency matching, developable, sweep along a path with edge matching, sweep along two rail curves with edge continuity, revolve, rail revolve, tween, blend, patch, drape, point grid ...

Use a two button mouse, use a big/second screen if you can. Drawing: (generally: you can either click to draw or type the dimensions you want) points circle line, polyline, lines (segments) rec polygon…
I'm working in Rhino. I was wondering what the command was for extrude planar surface. I have been using "extrudecrv" in the command line and unfortunately that is the wrong command for what I am trying to do.
