How to use the EXTRUDE command to make 3-D solids
« on: September 29, 2016, 05:08:09 pm »
These tutorials show an overview of how to use the extrude command on objects to create 3-D solids, and how to use PEDIT to edit lines to make them into POLYLINES so that they can be extruded too!

Tips:

-As you extrude from 2-D to 3-D, be sure that you are extruding objects (rectangles, circles, hexagons, etc.) or POLYLINES, rather than extruding individual lines. Objects and polylines extrude as solids, whereas individual lines extrude as flat, planes or surfaces.

-Be sure you are extruding in the "upward" direction (positive increments in the Z axis), rather than in the "downward" direction (negative increments in the Z axis). To check your positioning, you can view your drawing in elevation view using the view cube!
-Setting up a GRID for your project will give you a visual tool (like graph paper) that is positioned on the ground plane (the X,Y plane). Having your GRID turned on will help you to always know where the "ground" is!
