AI Drafting for MEP Engineering

MEP firms turn down work when there are not enough hands to put the drawings out. Nomic drafts the power, lighting, mechanical, plumbing, and fire protection sheets in CAD, in your layers and blocks, then checks them against the code and the architectural backgrounds before your engineers review and stamp.

The problem

MEP drawings wait on drafting hours

An MEP set is mostly production work. Someone lays out receptacles room by room, routes ductwork around the structure, draws plumbing risers, and repeats the same typical room across 112 guest rooms. Each architectural background update means another round of the same drafting.

Engineers end up drafting instead of engineering, and the review that catches coordination problems gets squeezed into the last week before issue.

01 / Layout

Ask for the sheet, get a DWG

Describe the drawing and attach the backgrounds. Nomic works in CAD on its own computer, reads the architectural plans and furniture layouts, and lays out the design on your layers with your blocks and text styles.

  • Power, lighting, and low-voltage layouts from furniture plans
  • Ductwork, diffusers, and equipment placed on the mechanical sheets
  • Plumbing fixtures, risers, and sprinkler heads drawn to scale
02 / Standards

Drawn the way your firm draws

Nomic uses your CAD standards file, title blocks, and symbol library, and follows how your firm drew the same system on past projects. The sheets look like your team made them, so review time goes to the design.

  • Your layers, blocks, line types, and text styles
  • Tags, keynotes, and general notes in your format
  • Title blocks filled in from the project sheet index
03 / Check

Checked before it reaches your engineer

Nomic checks its own drawing against the code edition you name and against the architectural set. Everything it drew is clouded, so your engineer starts the review with what changed and the questions it could not answer.

  • Checked against NEC, IMC, IPC, and NFPA requirements you name
  • Clearances and conflicts with the architectural background flagged
  • Open questions listed for the engineer of record

Checked against

The code and documents behind every sheet

Name the editions the project is designed to and Nomic checks its own drawing against them before handing it back. Your engineer or architect of record makes the final call and stamps the set.

  • NEC (NFPA 70)
  • International Mechanical Code
  • International Plumbing Code or UPC
  • NFPA 13 and NFPA 72
  • ASHRAE 90.1 and ASHRAE 62.1
  • Your firm CAD standards

How it works

From a sentence to a stamped set

  1. Step 1

    Ask for the drawing

    Say what the sheet needs to show and attach the backgrounds, markups, cutsheets, or photos. A sentence is enough to start.

  2. Step 2

    Nomic drafts it in CAD

    Nomic works in CAD on its own computer, on your layers and blocks, following how your firm drew the same thing before. It saves real DWG files to the project.

  3. Step 3

    Nomic checks its own work

    The drawing is checked against the code editions you name and the source documents. Everything Nomic drew is clouded, and open questions are listed.

  4. Step 4

    Your team reviews and stamps

    Your engineers and architects review the clouded changes, make the final call, and issue the set under their own stamp.

FAQ

Frequently asked questions

Yes. Nomic works in CAD on its own computer and saves real DWG files for power, lighting, mechanical, plumbing, and fire protection plans. It lays out the design from your backgrounds, applies your CAD standards, and checks the result against the code before your engineers review it.

No. Nomic is a new source of drafting capacity for your team. Your engineers set the design criteria, review every sheet, and stamp the drawings. Nomic does the production drafting and checks its own work before it reaches them.

Common starting points are receptacle and power plans, lighting layouts, ductwork and diffuser layouts, plumbing plans and risers, sprinkler layouts, equipment schedules, and existing conditions drawings from site walk photos.

Yes. Nomic draws on your layers, blocks, line types, text styles, and title blocks, and follows how your firm drew the same system on past projects.

Nomic produces DWG files and change lists your modelers can link into the Revit model. It does not author inside Revit. Teams that model in Revit use Nomic for the drafting and coordination work around the model.
