How to Create Floor Plans for Surveyors

For building surveyors and measured-survey professionals, the floor plan is the deliverable - and the bottleneck. A tape, a clipboard and a redraw back at the office can swallow an afternoon per property. This guide shows how to capture an accurate measured building survey on site, generate clean dimensioned plans with automatic room areas, and export straight to CAD or a branded PDF survey report, all from an iPhone or iPad.

Why surveyors need a faster way to capture floor plans

A measured survey lives or dies on two things: accuracy and turnaround. Manual measuring is reliable but slow, and every transcription from a paper sketch to a CAD drawing is a chance to introduce an error. When you are surveying a whole property - several rooms, multiple floors, awkward returns and recesses - the small mistakes compound, and the redraw is where the day disappears.

The shift in recent years has been towards capturing the geometry on site, in a form you can edit and export immediately. RoomPlot runs entirely on an iPhone or iPad, so the plan you walk out with is already most of the way to a finished drawing. There is no laptop on the bonnet of the car and no separate CAD session just to tidy up a sketch.

Capturing an accurate measured survey on site

RoomPlot gives you two ways to capture a space, and most surveyors use both depending on the job:

• LiDAR scanning on a Pro iPhone or iPad. Walk the room and the app detects walls, doors and windows automatically, building the geometry as you go. For a multi-room property you can scan room by room and bring them together.
• Manual drawing for spaces where you would rather key in known dimensions, or where a device without LiDAR is all you have to hand. Draw the walls and enter the measurements directly.

Whichever route you take, you are working in metric or imperial units throughout, so you stay in the convention your client expects. Snapping and a grid keep walls square and aligned, and undo/redo means a wrong move is never a problem.

Cleaning up the plan: dimensions, areas and multi-floor

A raw capture is rarely the final drawing, so RoomPlot lets you edit the full geometry after scanning. You can move, resize, rotate, add or delete any wall, door, window or opening, and multi-select several elements to adjust them together. On-plan dimensions and a scale bar make the drawing read like a proper survey rather than a sketch.

For area schedules, RoomPlot detects rooms automatically and calculates each area for you - or you can set an area manually where the geometry needs a judgement call. Every room can carry its own name, colour and label, and a report Area Summary collects them in one place. Because the app handles both metric and imperial, your area figures come out in the unit your client works in. Speak generally about accurate area capture: RoomPlot reports the areas it measures from your plan rather than computing a particular published measurement standard, so apply the convention your brief requires.

Surveying a house or a block? Add a floor for each level, switch between them, and combine floors into a single 2D plan when you need the whole property on one sheet. A true-north marker, set from the device compass, orients the drawing correctly for the record.

Exporting to CAD and branded survey reports

The export options are where on-site capture turns into a deliverable your office and your client can use:

1. DXF to CAD. Export the plan as DXF and open it in your CAD package to finish or annotate - rare on a mobile tool, and the reason many surveyors keep RoomPlot in the workflow rather than redrawing from scratch.
2. Branded PDF survey reports. Produce a clean, dimensioned PDF carrying your company logo, address and client details, with auto-generated legends and signatures. Notes, voice notes and photos captured on site flow into the report, so observations sit alongside the plan.
3. USDZ 3D and images. Share a 3D model or a quick image export when a client wants to see the space rather than read a drawing.

Projects sync across your devices via iCloud, so you can scan on an iPhone in the field and continue editing on an iPad back at the desk without re-exporting anything.

A practical on-site workflow

Pulling it together, a typical measured-survey visit with RoomPlot looks like this:

1. Set the project up and capture each room by LiDAR scan or manual draw.
2. Add a floor for each level and check the true-north orientation.
3. Tidy walls and openings, confirm the auto-calculated areas, and name each room.
4. Drop in photos and a voice note for anything that needs flagging.
5. Export DXF for CAD and a branded PDF report for the client.

Frequently asked questions

How accurate are RoomPlot floor plans for a survey?

LiDAR capture detects walls, doors and windows directly from the space, and you can refine any element afterwards with on-plan dimensions and snapping. For spaces you prefer to key in by hand, manual drawing lets you enter known measurements. As with any measured survey, sense-check critical dimensions on site.

Can I get my plans into CAD?

Yes. RoomPlot exports DXF, which opens directly in standard CAD packages, so you can finish, annotate or merge the plan with other drawings.

Does it handle multi-floor properties?

It does. Add a floor per level, switch between them, and combine floors into a single 2D plan when you need the whole property on one sheet.

Do I need a Pro device for LiDAR?

LiDAR scanning needs an iPhone or iPad Pro with a LiDAR sensor. On other devices you can still produce accurate plans by drawing manually and entering measurements.
