2D grids: definition (structure)

Definition

A 2D grid is defined by:

  • a name (and a comment)
  • a type
  • a coordinate system for definition
  • an origin (in a coordinate system for definition)
  • specific characteristics belonging to a type
  • a coordinate system for definition
  • attributes of color and visibility

Name

The name to identify the 2D grid is set by the user during the creation of this one.

A comment (optional) can be added to the name.
