Primitive Cone
Introduction
The primitive Cone is a predefined geometric shape that is used to create either a peaked cone or a truncated cone.
The primitive Cone can be created, modified, removed or used in other geometric operations (for example in a Boolean operation).
Structure of the primitive
The primitive Cone 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 point center of the circle that is the large base of the cone, or an existing point
- The dimensions of the Cone primitive (radius of the large base, radius of the small base and height) defined in the active coordinate system
- The appearance of the cone (color and visibility)

Result
The creation of a Cone primitive results in :
- Geometric entities (point, line, face, volume and object)
- A Geometric operation Cone_1. This geometric operation is a specific entity of the modeler that ensures the life cycle of the primitive (creation - modification - removal).
Access
The different ways to access the primitive Cone are:
