Why Green Road Group

Engineering automation built from practical experience

Built by the engineers who use them

We design roads, structures and networks — and we wrote these tools because the work was costing us days. Every plugin here started as something we needed on a live project, not as a product idea.

You write to the person who built it

There is no ticket queue and no support tier. A question about installation, licensing or a defect reaches the engineer who wrote the code.

Your drawings are never held hostage

Everything our plugins produce is ordinary CAD geometry. If a licence ends the features stop, but the drawings you have already made open, edit and share exactly as before — with or without our software installed.

Nothing leaves your machine

No drawing content, file names or project data are ever transmitted. There is no analytics package and no usage telemetry in any of our plugins — and one of them contains no networking code at all.

Featured plugin

Batch Civil Suite

Civil 3D does every one of these jobs perfectly well — once. The problem was never the tool, it was the count. Forty alignments, forty profile views, forty label sets, each one a dialog and a handful of clicks, and no part of it requiring a decision. That is the work this suite removes.
