This is one of the tools available through the Ruler Assistant Editor, and is created by building separate planes with vanishing points. You can create many planes, but if you’re creating a vanishing point perspective, make sure the vanishing points of all the planes meet in the same spot. A. Creating planes To create a plane, click in four places on your canvas. You can adjust the location of these points later on. You can also connect corner points of separate planes together.
B. Moving planes Each plane can be moved by clicking a mark in the centre and dragging it around. If the plane is connected to another plane it’ll also affect the other. C. Deleting planes Each plane can be deleted at any time by clicking a red X.
D. Vanishing point Each plane has its own vanishing point, even if they’re connected. If you want the vanishing points of multiple planes to meet, you have to do that manually. E. Creating a new plane from an existing one If your planes are connected, the easiest way to create a new one is to simply click and drag the mid-point on one of the existing planes’ sides. F. Turning planes’ visibility off To do this you need to click the eye symbol attached to the plane. This will make it invisible: the plane will fade and if you then decide to use the Brush tool with Assistant mode on it won’t affect the brush strokes.
