Extrude

Extrude is the way of transforming closed two-dimensional shapes (surfaces) into three-dimensional bodies. Squares can be changed into cubes and circles into cylinders. The way to extrude a two-dimensional closed shape is as follows.

1.Select the object to be extruded.
2.Click on the Extrude button in the Tools group, Edit tab, to start the extrude tool.
3.Change over to Perspective and move the mouse over the surface or the edge of the object. Now start the extrusion process with a click.
4.Control the shaping of the object by moving the mouse.
5.Extrusion is finished by either a mouse click or entering concrete values.

Enhanced Extrusion

If one closed 2D shape is inside another, extrusion is also a possibility. Tubes can be produced from two concentric circles or a number of shapes inside each other can give rise to a plate with notches or spaces in it.

The procedure for this type of extrusion is similar to that for simple extrusion (see above), but all the shapes that are to be extruded together must be selected at one and the same time.

1.Use multiselection (i.e., hold down Ctrl and click all the objects) to mark the objects that are to be extruded.
2.Click on the Extrude button in the Tools group, Edit tab, to start the extrude tool.
3.Change over to Perspective and move the mouse over the surface or the edge of the object. Now start the extrusion process with a click.
4.Control the shaping of the object by moving the mouse.
5.Extrusion is finished by either a mouse click or entering concrete values.

Enhanced extrusion means that the inner shape is deducted from the outer shape within which it lies. If closed drawing elements overlap and are subjected to the enhanced extrusion function, they will be united into one body.
