The sun never sets on the CADSharp empire. We have team members in North America, Europe, Africa, and Australia with a combined 50+ years of CAD and PDM development experience and fluency in ten different languages. Some of our key members include:

Keith Rice | Technical Director

Keith began programming with C++ and Visual Basic 6.0 while in high school. After studying mechanical engineering in college, he worked as an application engineer at a Cincinnati-based SOLIDWORKS reseller for three years. During this time he discovered the SOLIDWORKS API and realized he could combine his passions for programming and CAD. Surprised by the lack of quality API training and services, he started CADSharp in March 2011. Since then he has traveled the world teaching SOLIDWORKS API and has presented at SOLIDWORKS World on API topics over fifteen times. He is currently based in Vancouver, WA, with his wife and three young children. He loves learning about other cultures, climbing the Pacific Northwest Cascade peaks, and drinking Soylent.

Nilesh Patel | Project Manager, SOLIDWORKS API Developer, Mechanical Designer

Nilesh grew up in the Gujarat province of India, where he excelled at cricket and math. Forsaking his childhood dream of playing professional cricket, he studied undergraduate mechanical engineering at The North Gujarat University before moving to Adelaide to receive a master’s degree in the same subject. Remaining in Australia (where he is now a citizen), Nilesh worked as a design engineer in Brisbane where he began studying SOLIDWORKS API. He joined CADSharp part-time in 2018 and then full-time in 2019, where his deep design background gives him great insight into the automation needs of our customers. He is happily married with one son, despises vegemite, and enjoys reminding Kiwis that New Zealand is basically Australia’s Canada.

Jacob Corder | SOLIDWORKS API and Onshape Developer

Jacob’s storied career began as a mechanic for F-15 fighter jets in Alaska, where he served his country for four years. Afterward he worked as a product designer and CAD technician in the years leading up to his graduation from Hennepin Technical College, where he studied fluid power engineering. His exposure to the SOLIDWORKS API occurred during his next job as a hydraulic system designer. His prolific and innovative use of it led to his appointment as a full-time software developer, where he wrote possibly the most complex SOLIDWORKS addin known to man, totaling over half a million lines of code. In late 2019 he joined CADSharp as our first full-time Onshape developer. He currently lives with his wife and daughter in Minnesota, where he enjoys remodeling his house, staring longingly across the Canadian border, and tinkering with his remote-controlled lawn mower.

Services Testimonials

I cannot speak highly enough of your work and professionalism. You’ve been a pleasure to work with on this project.

Drew A.,

Just wanted you to know the tool you developed for us is TERRIFIC. I just updated over a hundred SW files. Took about 5 hours to create the Excel file, edit the damn thing, then upload the corrections. The creation and uploading took about 10 minutes. The other 4 hours and 50 minutes was my thinking time. This one edit saved me literally days of work. So happy!

Dennis B.,

The program is glorious.

Michael F.,

Amen is a wizard. We did some Teamviewer sessions together to get some bugs fixed and Amen never backs down for anything. He is fast, reliable, and a very experienced. I really enjoy working with him on our current projects and, of course, [will utilize him for] any future ones.

Martin V.,

I know you’re already well aware of this, but Amen is a total rock-star and he’s helped us look like total pros in front of our customer. Because of the quality of his work, I’m sure we’re going to have a long-term and profitable relationship supporting them.

Chris C.,

We use the tools every day, and we couldn’t imagine life without them now!

Your tutorials have helped overcome the steep learning curve of SolidWorks APIs. I studied the free ones first, and we upgraded. I would just like to say that you do online tutorials very well. I will recommend your site to anyone wanting to learn to teach online, or learn SolidWorks API programming.
