The 3D-Box tool draws a (simulated) three-dimensional box. To understand how it works, it helps to know a little bit about drawing in perspective. This tool is of interest to people who want to draw architecture or interiors. It makes it really easy to create furniture or rooms, because it automatically creates perspective, by making use of vanishing points.
After click-and-dragging with the tool active, a box appears on the canvas. This is best done somewhere near the center of the page area. Else, the box can sometimes end up quite deformed. By default, two vanishing points are placed in the vertical middle of the page borders, one on the right, the other on the left.
When you look closely at the 3D-box that you have drawn, you will see the following:
- A small black crosshair, which designates the center of the box. When you click and drag it with your mouse, the box will move along with it, apparently in 3D space. Depending on its position in relation to the vanishing points, you will be able to see the box’s bottom, or its top. If you move the box to the left or right, its shape will change in accordance with the vanishing lines.
- Numerous (to be exact, 8) white, diamond-shaped handles allow you to extend or shrink the box along the x, y or z axis by dragging them with the mouse.
- The white, square-shaped handles symbolize the vanishing points and can be moved in the same fashion as the other handles.
Note that these specific changes can only be achieved when you use the 3D-box tool. If you move the box with the Selection tool, both the box and the vanishing points will move.
The tool controls for this tool allow you to set parameters for the 3 vanishing points for the x, y and z axis. The buttons with the icon depicting two parallel lines will make the vanishing lines parallel and have an immediate effect on the box on the canvas.
