- MESH allows you to define a surface and then generate a
- set of polylines (a mesh) that approximates the surface
- to a user-specified level of accuracy. It allows you to
- generate a polyline mesh approximation of a two-curve,
- three-curve, or four-curve swept surface; a tabulated
- cylinder; a surface of revolution; a sphere; or a ruled
- surface.
-
-
- Create the polyline mesh by choosing from the following
- options:
-
- 2 CURVE - to create a polyline mesh defined by a selected
- generator curve and a director curve. The mesh
- approximates the swept surface that is formed by moving
- (sweeping) the generator curve along the director curve.
-
- 3 CURVE - to create a polyline mesh defined by either
- two generator curves and a director curve, or by one
- generator curve and two director curves. The mesh
- approximates the blending of the two, two-curve surfaces.
-
- 4 CURVE - to create a polyline mesh defined by two
- generator curves and two director curves. The mesh
- approximates the blending of the four, two-curve surfaces.
-
- TAB CYL - to create a polyline mesh approximation of the
- surface defined by sweeping a generator curve along an
- axis vector (the director) of a specified length.
-
- REVOLUT - to create a polyline mesh that approximates the
- surface formed by rotating a generator curve about an axis
- by a specified angular distance.
-
- SPHERE - to create a polyline mesh that approximates a
- sphere. Create a sphere in either of the following ways:
-
- a) By specifying the center and radius of the sphere, as
- well as the number of latitude and longitude lines.
-
- b) By specifying the center and diameter of the sphere, as
- well as the number of latitude and longitude lines.
-
- RULED - to create a polyline mesh that approximates the
- surface formed by simultaneously moving a line (generator)
- along two director curves.
