We're MACDAC Engineering

Our Story

Dedicated to helping you succeed

Founded in 1991, MACDAC Engineering has consistently been among the top 10 Mastercam resellers across North America for both sales and growth.

In 2002, several employees purchased MACDAC Engineering from the original owners, armed with a focus to drive continual improvement throughout the company.

MACDAC Engineering offers solutions for designers and NC programmers involved in milling, routing, turning, wire EDM, plasma cutting, lasers, and 3D design/solids and drafting. Our customers range from one-person job shops to Fortune 500 manufacturers. The same software that is utilized by large corporations is still affordable enough for the small job shops.

Our Growth

MACDAC Engineering is part of the TriMech Group

MACDAC Engineering was purchased by the TriMech Group in 2022, and has grown to have more than 50 locations across four countries - the United States, Canada, the United Kingdom, and Ireland. Our 650 exceptional employees, including hundreds of application engineers, work in nine time zones and serve more than 30,000 clients.

TriMech has expanded both organically and through smart acquisitions that have added talented teams and leading technology. This growth allows us to continually enhance our core products and services while increasing our ability to deliver more for clients who need it.

Our strength will always be our skilled and caring people. As we expand our already strong technical teams, you have access to even more experts who can optimize the ways you use technology and support every facet of your business.
