# Paths: definition (structure)

## Definition

A path is defined by:

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

## 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 path

The different types of paths and the characteristics useful for their description are presented in the table below.

Type Characteristics
path defined by two points

starting point (coordinates)

ending point (coordinates)

Type Characteristics
arc path defined by three points

starting point

(coordinates)

middle point

(coordinates)

ending point

(coordinates)

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

center point

(coordinates)

starting angle

ending angle

Type Characteristics
parametrized path coordinate system for definition

functions

(coordinates dependent on parameter)

parameter variation

(minimum and maximum)

It is not possible to modify a path.
