Path: definition (structure)
Definition of a path
A path is defined by:
- a name (and a comment)
- a mechanical set (if it is the case)
- a list of sections
Definition of a section
A section is defined by:
- a name (and a comment)
- a type
- specific characteristics (depending on the type)
- a region
- a discretization
- color and visibility attributes
Name
The name to identify the path is set by the user during the creation of this one.
A comment (optional) can be added to the name.
Types of sections
The different types of sections and the characteristics useful for their description are presented in the table below.
| Type | Characteristics | |
|---|---|---|
| section defined by 2 points | point origine (coordonnées) | point extrémité (coordonnées) | 
| Type | Characteristics | |||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| arc path defined by 3 points | starting point (coordinates) | middle point (coordinates) | ending point (coordinates) | |||||||||
| arc defined by center, radius and angles | coordinate system for definition | center point (coordinates) | radius | starting angle ending angle | ||||||||
| Type | Characteristics | ||
|---|---|---|---|
| parameterized path | coordinate system for definition | functions (coordinates dependent on parameter) | parameter variation (minimum and maximum) | 
| Type | Characteristics |

| parameterized path | existing line | 
It is not possible to modify a path.
