Draw your rooms like any planner. Then type what the tape measure says — 12′-6″ stays exactly 12′-6″, no matter what you move next. No CAD to learn, nothing to install.

Made for your project
Sketch the house you actually live in — type the tape-measure numbers and they hold. When the county asks for a to-scale drawing, the sheet comes out with the title block, scale bar, and checklist already done. No CAD class, no $800 drafting bill.
Kitchen-and-bath runs held to the 1/16″ — a locked dimension can’t drift into a $2,000 re-order. Mark walls existing / new / removed, drop the smoke and CO symbols the reviewer looks for, and walk in with a scaled PDF instead of waiting a week on a drafter.
Parallel, perpendicular, equal, pinned — actual solved geometry, not drag-and-snap. Rough out schematics anywhere, trace a client’s photo of their existing plan, and hand off a clean DXF that opens on named layers in your CAD of choice.

This is the editor’s actual behavior, running right here: pinned measurements hold, and everything else re-solves around them. Go ahead — it’s the real math.
The coral number is locked. Try to make it move.
From blank sheet to finished plan
If you can drag a rectangle and read a tape measure, you already know how to use Trammel.
Drag out rooms, start from a template, or trace a photo of your existing plan. Walls join and square themselves up as you go.
Click any dimension and type what the tape measure says. Set it and it’s set — the rest of the plan adjusts around your numbers.
A to-scale PDF for the permit office, a clean image for the listing, DXF for the pros. Your plan leaves in whatever format the next person needs.
Sheet A-100 · the workflow
The three jobs people actually show up with: a site plan, an as-built of what’s there, and a sheet the county accepts.
Type your address and Trammel pulls the real parcel lines from public records — then lay your plan out on the lot over an aerial view, and watch the setback distances to every property line update as you draw. That’s the site plan most permit applications ask for, without hiring anyone.
Planning-grade parcel data from public GIS records — coverage varies by county, and it’s not a survey.
Photograph the old blueprint — or drop in a PDF — and it becomes an underlay. Give Trammel one measurement you know, it calibrates the scale, and you trace crisp, exact walls right over the fuzzy original. The fastest way to an as-built you can actually trust.
Export a to-scale PDF with the title block, graphic scale bar, and north arrow already drawn. Before you print, the readiness checklist flags what residential plan checkers bounce most — missing scale, unnamed rooms, absent smoke and CO alarms — so your trip to the counter is the last one.
Requirements vary by jurisdiction — the checklist covers the most common residential checks.
Leaving Trammel · your plan is yours
No credits and no per-export fees on any plan — the free tier exports PNG forever, and Pro is one flat price for every format.
On every plan, forever — for listings, emails, and texting the contractor. Hi-res without watermark on Pro.
To a real architectural scale on real paper sizes — the permit deliverable.
Crisp vectors that open in any design tool, at any size.
Opens on named layers in AutoCAD and every other CAD tool — the architect handoff.
The difference · measurements that stay put
People who use drag-and-drop planners keep reporting the same thing: “measurements change on their own after being set.” Trammel is built so that can’t happen. Set a wall to 12′-6″ and it’s locked — everything else adjusts around it, and your number survives every edit that follows.
Sheet A-101 · what you get
Drag-and-drop planners lose your numbers. Pro CAD costs $100 a month and a week of training. Trammel is the middle you’ve been asking for: draw walls, doors, and windows the easy way, and trust every measurement on the sheet.
Click any dimension, type what the tape measure says, and lock it. Move anything else — the rest of the plan adjusts around your number instead of quietly changing it. It’s the same constraint-solving math professional CAD uses, minus the CAD.
Every wall shows its length while you draw and stays editable after. Snapping reads your intent — square corners, even spacing — so the plan tightens up as you work instead of drifting apart.
Close a loop of walls and it becomes a room with a name and a live area label. Resize anything and the square footage updates instantly — no calculator, no counting grid squares.
Every edit saves to your device first and syncs to the cloud when you’re back online. Measure and draw right where you’re standing — nothing is held hostage on a server.
Feet-and-inches or metric, switchable per plan. Dimension entry parses what you type, either way — Trammel speaks whatever language your tape measure does.
