Extruding a shape

To turn a 2D shape into a 3D extruded object, go into the Extrude Tool on the main toolbar and simply click and drag on your object to rotate it in 3D space.

Initially, your extrusion is given a default depth. The face color of the 3D shape is determined by the fill color of the original shape and the color of the extrude (or side) by its line color. After creating an extrude in this way, move your mouse pointer around over the 3D object. You'll see that the mouse pointer changes as follows to indicate what will happen if you click and drag at any point:

	This is shown when the mouse pointer is over the front or back face of the object. Clicking and dragging rotates the object in 3D space.
	This is shown when the mouse pointer is over the extrusion (the side) of the object. Clicking and dragging changes the depth of the extrusion.
	This is shown when the mouse pointer is over the extrusion and "Ctrl" is held. Clicking and dragging changes the bevel size (see below)

You can also rotate an extrusion by holding down the Alt key while dragging on the extruded side. This is useful when only the side of an extrude is visible and so you aren't able to drag on the face in order to rotate it. As when dragging on the front face, Ctrl and Shift can also be used to constrain the rotation.
