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


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


point extrémité


Type Characteristics
arc path defined by 3 points

starting point


middle point


ending point


arc defined by center, radius and angles coordinate system for definition

center point



starting angle

ending angle

Type Characteristics
parameterized path coordinate system for definition


(coordinates dependent on parameter)

parameter variation

(minimum and maximum)

Type Characteristics
parameterized path existing line

It is not possible to modify a path.
