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


middle point


ending point


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

center point



starting angle

ending angle

Type Characteristics
parametrized path coordinate system for definition


(coordinates dependent on parameter)

parameter variation

(minimum and maximum)

It is not possible to modify a path.
