Extruded Surface


The Extruded Surface entity is based on a BSpline Surface or Mesh depending on the type of definition curves and generates a shape by either linearly extruding a surface through a single curve or by sweeping a "shape" curve along a "path" curve. The extruded surface can be edited by modifying its definition curves although the surface itself can be extracted as a BSpline Surface.


Right-Click -> Multiple Selection -> Extruded Surface

Create a Extruded Surface by selecting 1-2 of any BSpline curves, Polylines, Cubic Splines or Interpolating Cubic BSplines.
