You can use Shift+drag without releasing the mouse button to extrude in Z direction. Press X or Shift + F4 to switch to the 3D Box Tool. Note : Parallel lines do not necessarily have to be 90 degrees to X axis - changing the angle will somewhat skew the object. X and Z planes nearly converged, but Y is more or less the same.īy default Inkscape makes X and Z lines converging, because it represents usual perspective. Here is what happens when you keep moving borders of X and Z planes closer to vanishing points: Here is a sample to illustrate how it works: If lines are converging, they have a vanishing point - a point where they cross.

yellow lines stand for Z direction (depth).

blue lines stand for Y direction (height).

red lines stand for X direction (width).

These lines are drawn in different colors, so that users could distinguish one line from another: In order to represent an object in 3D (it's emulated 3D, so it's rather 2.5D), the 3D box tool deals with axes (XYZ), planes (XY, XZ, YZ), parallel lines (PL), converging lines and vanishing points (VP).Įach dimension can lie on either parallel or converging lines.

The tool automatically ensures that all sides of the box lie on the corresponding perspective lines. The 3D box tool helps you create such drawings by automating the most common operation: creating a box in a given 3D perspective. However, very often it is used to create drawings or objects that appear three-dimensional. Inkscape is a two-dimensional drawing tool.
