Point: about


Points can be created:

  • manually (entering coordinates)
  • by propagation from existing points, with the aid of a transformation
  • within the propagation or extrusion from other entities

Point coordinates

A point could be defined by its coordinates in a coordinate system for definition (see Coordinate system: about ).

Point defined by propagation

A point could be defined by propagation from another point with the aid of a transformation.

Parameter setting

The point coordinates can be defined using algebraic expression. The algebraic expression can contain:

  • constants
  • geometric parameters (created beforehand)
  • basic mathematical functions using operators : +, -, *, /, ( )
  • usual mathematical functions admitted by FORTRAN

The mathematical functions are described in section Functions.
