StlWork is a Low Cost 3D solid/surface tool path development system for CNC Machining. 

In order to use it you will need 3D models.  Models can be in a variety of  formats, but they have to eventually be translated into STL to be used by StlWork.  We include a copy of StlTrans with StlWork to make it easier to find existing models or applications that can design a model.  This page is an alphabetical list of compatible, low cost, 3D cad programs that are capable of designing models for use with StlWork.

How do we decide what programs to include? All programs on the list are less than $1000. They are all capable of designing 3D solid models that can be saved directly as Stl, or can be translated into Stl by StlTrans.  None of them are part of a competitive Cad-Cam product.

Prices were as of July 10, 2001.  If you know of additional products that may be available for less than $1000, please let us know at : The versions listed were available on-line for the prices shown.  Note: In many cases there are older versions of the same software available for much less money, even free, and sometimes upgradable to the latest version!  If you are on a tight budget, check out E-bay and other software sellers for retail boxed copies of some of these programs available for pennies on the dollar.
