About ParaMatic

Engineers who write their own tools.

Marhinus du Plessis founded ParaMatic in February 2018 to automate the way engineering is done. Today our drawing office in Paulshof, Johannesburg uses Tekla tools that our own developers write.

Our story

Started in 2018 to automate engineering.

Marhinus du Plessis founded ParaMatic in February 2018. He saw first-hand how slow the old ways of engineering were, and he knew there was a better way.

So he set out to build software that automates engineering from concept to production. The software does the repeat work, so engineers can spend their time on the creative work.

The name says it too: ParaMatic joins "parametric" and "automatic".

Today we are a team of detailers, engineers and developers in one office in Paulshof, Johannesburg. Most of our work is for mines and the plants around them.

Our missionTo transform the way our clients engineer, with innovative platforms and automation.

Our vision
To be a world leader in getting accurate, useful engineering data to the construction industry.
Our values
Passion, innovation, efficiency, accuracy and quality.
Two arms

Two arms, one office.

ParaMatic is a group of two companies. ParaMatic Projects does the engineering. ParaMatic Developments, our research and development arm, writes the Tekla tools. Our drawing office uses those tools every day.

Marhinus du Plessis, founder and CEO of ParaMatic
Leadership

Led by an engineer who writes code.

Marhinus du Plessis is our founder and CEO. He has worked as a boilermaker, an OEM designer and a site supervisor, and for more than 13 years as a structural and mechanical designer on industrial projects.

He started our piping add-on himself, on the Tekla API. Today he leads both our engineering projects and our Tekla developments.

"There's no limitation to what you can do through the API."
