Detailed Description

Defines a plane.

A plane is defined by an axis placement. The following image depicts a plane example:

Plane

A plane is parameterized as follows: \(\mathbf{S}(u,v) = \mathbf{P} + u\mathbf{D}_x + v\mathbf{D}_y\), where

\(\mathbf{P}\) is an origin point,
\(\mathbf{D}_x\) and \(\mathbf{D}_y\) are directions (unit vectors) of X and Y axes respectively,
\(u\) and \(v\) belong to \((-\infty, +\infty)\).

U- and V-parameters are lengths along respective axes. U-isolines are lines along Y axis, V-isolines are lines along X axis.

Examples: exploring/brepgeometry/Program.cs, exploring/brepgeometry/main.cxx, modeling/assembly/Program.cs, modeling/assembly/main.cxx, modeling/brep/Program.cs, and modeling/brep/main.cxx.
