Some of the work I've done over the years:

The following images are scanned from pen/pencil on paper/Mylar:

The following images are either screen shots or rendered in Pro/PHOTORENDER:

           

The following are images of a truck dash, which was modeled from scratch to accommodate
different body widths and be as fully modifiable as possible.
 
       

The following is a driver ergonomic study - the skeleton part includes surfaces for eye
ellipse, head contour, belly and knee contours and hand reach zones, and is driven by
Pro/LAYOUT. The layout contains many relations that allow any variations of design
to be accommodated very quickly. Based on SAE standards.
   

 

   

    

The following is an articulating assembly of a front steering axle. Geometry was constructed to allow different spring heights from side to side, and different steering angles. The assembly is controlled by a layout, with hundreds of parameters and relations. The user has a choice of over 100 axles, 40 springs, 100 wheels, 40 tires. By simply typing in the appropriate part numbers, the assembly generates accordingly. An automated process was added to generate a part containing the tire swept volume surfaces.

   

Truck dash assembly. The dash itself was remodeled from scratch to accurately record an existing part, for retooling. C2 surfaces on the A-surface, drafts and rounds included.

Chassis design:

The following tri-steer axle system was developed from the ground up, with all new components for the suspension and steering. A skeleton model was created that allowed variations in wheel angles and suspension heights, which controlled the placement of the real component models in the top assembly.
