Questions We Hear Before Every Mechanical Engineering Project

What CAD software do you work in?

SolidWorks, CATIA, and Fusion 360 most often, matched to your own file format so revisions stay compatible with your existing design history rather than forcing a conversion.

Can you take over a design that is already partway through development?

Yes. We review the existing CAD, drawings, and any DFM notes first, then scope the handoff so nothing gets rebuilt that does not need to be.

Do you design for injection molding and sheet metal, or only general mechanical parts?

Both. Plastic and sheet metal design for production is one of our three core mechanical service areas, with draft angles, wall thickness, and bend allowances built into the CAD from the start, not corrected after tooling.

How is a mechanical engineering project priced?

Scoped and quoted up front from your requirements, with revisions included in that scope. You will not receive a surprise invoice for extra time.

Working with Cadlete Designs has been a real pleasure. They helped with so many design aspects I hadn't considered and offered many suggestions that I would have never thought of. Professional, prompt, and always willing to go the extra mile. I was extremely lucky to have found them! (Patent Pending)

These guys are simply the best. They are professional and on time with the orders and take great care in understanding what it is you want done. They offer revisions on the product if it is off and they are so pleasant to work with, I would 10/10 recommend them to anybody looking for designs drawn up.
