Geometric parameter: about

Principle of use

Geometric parameters are entities that can be used for the geometry building of the device, i.e. for the definition of points, coordinate systems, geometric transformations, infinite box dimensions and other geometric parameters.

The modification of a parameter is immediately reflected on the geometry, i.e. on the points, lines, faces and volumes, but the topological coherence of the obtained geometry is not controlled, the user must check it himself.

Example

To describe the device represented in the figure below, three geometric parameters are used.

• The half width of the bar:

  HWIDTH_BAR = 5 mm

• The half height of the bar:

  HHEIGHT_BAR = 10 mm

• The internal radius of the torus:

  INTRAD_TOR = 2 * HWIDTH_BAR

  = 10 mm
