CAD Modeling
I use SolidWorks, Pro/ENGINEER Wildfire, AutoCAD and other CAD applications to make 3D CAD models, typically in support of product development and manufacturing. The CAD models are used as the basis for CAD drawings, renderings, and for processing technologies such as rapid prototyping, machining and fabrication.
Having thousands of hours of experience using various CAD applications, I can model pretty much anything by now. Very simple projects may require an additional cup of coffee.

CAD Drafting
The kind I do is mechanical as opposed to architectural. The typical output is an engineering drawing or drawings package that conforms to ANSI or ISO standards and that serves to document a component, product, tool or machine for build or record-keeping purposes.
In addition to documenting my own designs I offer general CAD drafting services such as conversions, revisions or red-lines, detailing of existing models, and checking or review of drawings to standards.

Tool Design
My expertise in this specialty comes from thousands of tool design projects, most of which are fixtures and special machines used to develop and manufacture products. Before switching to design full time I worked for several years as a Tool and Die Maker, and CNC Programmer. My first all-design position was as a Tool Designer. Knowing how to build the tooling helps greatly in designing it. I have experience with: molds for plastic, sheet metal dies, machining fixtures, assembly fixtures, automated equipment, capital equipment, and special machines.
If you want me to have the tooling built I can do that for you, too.
This list is representative of the kinds of tooling and equipment projects I have done:

Product Design
I consider products in terms of their end use and in terms of how they are to be produced. A balanced design solution is the result.
The CAD part of product design that I do includes modeling, drawing and renderings. I also provide: project management; sourcing; liaising with vendors who produce and assemble; and subcontracting of other design and engineering specialties. I can design a single component or take on an entire product design project from concept through to production and delivery. Whichever way I am involved, my broad knowledge and experience along with my handy network of associated professionals translates into a great result for my customer.
If you need prototypes I can arrange to have those made.

I must have done something right!
“Paul is very detailed oriented and handles any design project with professionalism. He is very thorough and a pleasure to work with. He works very well with manufacturing by including them in early design decisions that would relate to later manufacturability issues.” - Kevin N.
"I have received feedback on your work and it has been very positive. I am not sure what your plans for the future are, but we'd like to continue to get help from you..." - Rudy G.
