Blueprint Maker

Blueprint Maker: Plans a Contractor Can Actually Build From

A blueprint is a floor plan you hand to someone else — a contractor, an architect, a cabinet maker, a landlord — so it has to be clear, measured and printable. Draw yours to scale, switch to a classic black-and-white blueprint style, pin notes where the work happens, and export a print-sharp PDF up to A0 or a layered CAD file.

Export exactly what the job needs

One export dialog decides what goes on the sheet. Tick Black & white for the classic architectural line drawing, keep Measurements and Labels on, and add elevation views or an electrical plan when the trade needs them. Choose a paper size and quality, and the plan fills the page at a resolution that stays sharp when printed large.

PNG for email, or PDF for printing — up to A0
Measurements: wall lengths and segment dimensions
Labels: room names and the names of fixtures and furniture
Electrical plan: outlets, switches and lights on their own

Every export option

Notes where the work happens

Instructions written on a separate sheet get lost. Drop a sticky note right on the wall, window or cabinet it's about — "move this outlet 12 in left", "remove this wall" — and it prints as a numbered pin on the plan, with every note written out in full on a notes page.

Rename rooms, label any object, and the labels print too, so everyone talks about the same "pantry".

Notes, labels and blueprint style

Walls drawn straight-on, with heights

A floor plan shows where things are; an elevation shows how high. RoomSketch3D draws each wall face-on with real heights — windows and their sills, railings, bulkheads — dimensioned like an architect's drawing and ready to export with the plan.

Elevation views

Hand it to an architect in CAD

If your plan goes on to a designer or architect, export a layered AutoCAD DXF. Exterior and interior walls, doors, windows, furniture, fixtures, stairs, dimensions and text each arrive on their own layer, at real scale, so they can keep working from your measurements instead of redrawing them.

What it does — and what it doesn't

It does

Draws to exact scale in feet and inches or metric
Exports a black-and-white blueprint-style PNG or PDF, up to A0
Prints numbered notes with a full notes page
Shows elevations of every wall with real heights
Exports a layered AutoCAD DXF and a 3D model
Handles multi-story homes, stairs and basements

It doesn't

Produce stamped or engineered construction drawings
Do structural, load or energy calculations
Draw building sections, foundation or framing details
Replace a permit set where your city requires one from a licensed professional

Blueprint Maker questions

Straight answers, including the limits

Can I make a real blueprint with RoomSketch3D?

You can make an accurate, dimensioned, printable floor plan in a classic black-and-white blueprint style, with labels, notes and wall elevations — which is what most homeowners, contractors and cabinet makers mean by a blueprint. It is not a stamped construction drawing; if your city requires drawings from a licensed architect or engineer for a permit, use RoomSketch3D to work out the layout and hand them the plan.

What sizes can I print?

PNG for screens and email, and PDF sized for paper from standard prints up to A0, at a resolution chosen to stay sharp at that size. You can also print directly from the app.

Can my architect open the plan in AutoCAD?

Yes. Export a layered AutoCAD DXF at real scale — exterior and interior walls, doors, windows, furniture, fixtures, stairs and dimensions each arrive on their own layer.

Can I add notes for the contractor?

Yes. Pin a sticky note anywhere on the plan; it prints as a numbered pin, and the export adds a page with every note written out.

Is the blueprint maker free?

No. RoomSketch3D is $19.99 once — no subscription and no free trial — with a 30-day money-back guarantee. Every export format is included.
