Torus drafts complete engineering packages.

Every plant, pipeline and substation starts as thousands of pages of drawings and calculations.

With Torus, your engineers can draft them 9.7x faster.

Backed by Y Combinator

The whole package.

A real one: a gas receipt meter station, drafted in the firm's format and issued for review.

Every discipline.

Process, piping, electrical and controls, drafted as one set. Every value is checked against every sheet that carries it, so a change on one reaches the rest.

9.7x faster

drafting a package

One EPC timed its engineers drafting the same package with and without Torus.

Every project gets its own inbox.

Cc it on project email: your team, vendors, subcontractors, anyone on the job. When a message changes a design value, Torus redrafts every sheet it touches and sends them to your engineer to check.

REUpstream pressure confirmed
Sarah, the pipeline confirmed the upstream line runs at 1,480 psig.

2Torus works out what it changes

FROMmeter-station@meridian.usetorus.cc
That's above the 1,440 psig the relief valve is set for, so a blocked outlet becomes the governing relief case and the valve has to get bigger. The three sheets it changes are redrafted and the outlet pipe is flagged for resizing, ready for your check.

Every value has a source. Every decision has an owner.

It's hard to build in America.

Projects are getting bigger and the teams aren't. Every substation, pipeline and treatment plant runs on thousands of documents across dozens of firms. Torus compresses the engineering schedule, so there are fewer change orders and projects reach delivery sooner.

Torus gives every engineer the capacity of a team.

137,000 engineering firms, every one on a different sheet
