Engineering Graphics Program: 3D Modeling & Rapid Prototyping

The Engineering Graphics department is currently using a couple of Rapid Prototyping systems in the mechanical program. Students registered in CAD-202 and CAD-262 are able to start working in 3D and model their assemblies digitally and in the 3D printer.

Rapid Prototyping enables students to test, review, analyze, and proof their design. 3D modeling allows to prove the functionality and engineering of assemblies.

3D CAD Printing Classes

You will need a solid foundation in AutoCAD, CAD-101 and CAD-102, or an EGT department approved equivalent modeling background to enroll in these classes. 

CAD-202 / CAD-262

These two beginning modeling classes are taken back-to-back in one semester and are offered each Spring and Fall semester. You will begin 3D modeling with basic shapes and techniques and quickly advance into multi piece assembly projects. FORM – FIT – FUNCTION of the completed model will be our guide.  You will do some simple LISP programming. Basic kinematics will also be introduced and used in the design process along with XREFERENCING. The semester will explore design concepts, shop processes, presentation drawings, and building the working multi-piece 3D plastic models. Various reference manuals and design materials will necessarily be utilized in the classes. All models will be built using the Stratasys/Dimension 250-MC or 1200-ES modeling machines in the EGT department. Lots of work and lots of fun learning by doing.  Upon successful completion you will have presentation drawings and working models.


In the continuing classes you will be expected to do more self-directed engineering design, reverse engineering, and problem solving. With initiative you will further develop your independent design skills while producing larger more complex project assemblies and presentation drawings.
