Let us aid you in designing your castings -- we can help you express your design cost effectively. With AutoCAD Mechanical Desktop® we can work directly with your 2D or 3D data. 3D models can easily be used to make patterns with the use of Mastercam®. Direct model to metal pattern machining! Rapid prototyping resources are available for quick hands-on models. Stereo lithography is one of the most common ways to produce these models. In some cases these models can be used to quicky create a rough pattern for rapid, cast prototypes.
