Primitive Block
Introduction
The primitive Block is a predefined geometric shape that is used to create a parallelepiped.
The primitive Block can be created, modified, removed or used in other geometric operations (for example in a Boolean operation).
Structure of the primitive
The primitive Block is described by:
- A coordinate system for the creation of points ( active coordinate system in the list available on the graphic View)
- The coordinates of the origin point of the parallelepiped base or an existing point
- The dimensions of the parallelepiped (length, width, height) defined in the active coordinate system
- The appearance of the parallelepiped (color and visibility)

Result
The creation of a Block primitive results in the formation of:
- Geometric entities (point, line, face, volume and object)
- A Geometric operation Block_1. This geometric operation is a specific entity of the modeler that permits to ensure the life cycle of the primitive (creation - modification - removal).
Access
The different ways to access the primitive Block are:
