This tool is used to display lines in single, double, and three-point perspectives. When this tool is enabled, the lines drawn with the Brush tool or the Line tool are aligned in the direction of vanishing points.


To display the perspective lines:

•Select the perspective tool

•Move vanishing points

•Add or remove control points

Moving perspective points


The displacement of the center of the perspective, materializing the horizon line, displaces the set of vanishing points and control points. If you press the Control key simultaneously while moving the center, only the vanishing points are moved with the center.


Each control point (red) has 3 associated points (yellow, green and blue) to adjust the dimension of the perspective figure.
