Roomcraft / Drafting studio

AI blueprints & architectural drawings.

Generate professional-grade blueprint layouts, elevations, and sections — and learn to read the symbols, dimensions, and US / Massachusetts building codes behind them.

Measured plan · to scale

Your exact space, drawn to scale

AI reads your photos to find the rooms, doors and windows. You confirm the real measurements, and the plan is drafted with exact geometry, ready to export as PDF, DXF, DWG, IFC (Revit), TIFF and more.

01 · Photos of your space

02 · Measurements

0 SF

Type real tape-measure numbers (12'6", 12 6, or 150").

Upload photos and scan, try the sample, or add rooms by hand. Your to-scale plan appears here.

Drawn from your numbers with exact geometry: dimensions are to the interior face of walls, partitions 4½". Prints at 1/2" = 1'-0".

Export

.RVT / .RFA are Revit-only files. Use the .IFC export: in Revit choose Open → IFC (or Link IFC) to get real walls, doors, windows and rooms. Field-verify all dimensions; permit sets need a licensed professional.

AI-generated drawings are concept studies, not permit-ready construction documents. A licensed MA architect or engineer must stamp anything submitted for a permit.

Read the drawing

Architectural symbols, decoded

The twelve marks you'll see on almost every residential plan set — and how to read them.

◜

Door swing

A quarter-circle arc shows which way a door opens and its width. The gap in the wall is the opening.

▯

Window

Three parallel lines breaking a wall. The sill height and size are noted beside it (e.g. 3050 = 3'-0" × 5'-0").

▮

Wall (new)

Solid filled or hatched thick lines. Exterior walls are drawn thicker than interior partitions.

▭

Wall (existing)

Often shown lighter or dashed in remodel sets, sometimes labeled 'E' or 'EXIST'.

↔

Dimension string

A line with tick marks and numbers like 12'-6". Read outside-in: overall, then openings, then details.

⦿

Section marker

A circle or flag with a letter/number (A / A-301) telling you which sheet shows that cut-through view.

◇

Elevation marker

A diamond or triangle pointing at a wall, referencing the sheet with that exterior/interior face view.

↑

North arrow

Orients the plan. Required on site plans; drives solar, setback, and code decisions.

◍

Electrical outlet

Small circle with two lines. '$' marks a switch, a triangle often marks a 220V or special outlet.

¼"

Scale note

e.g. ¼" = 1'-0". One quarter inch on paper equals one foot in reality. Never measure a printed PDF without checking the scale.

⊣

Datum / level

A marker with an elevation like +9'-4", measured from a reference point (often finished floor = 0'-0").

Aa

Room label

Room name plus finish floor or area, e.g. 'KITCHEN 214 SF'. Ceiling heights are noted as 'CLG HT 9'-0"'.

US / Massachusetts codes

Understanding the code behind the drawings

The codes that govern in Massachusetts

  • 780 CMR — the Massachusetts State Building Code (9th edition), based on the 2015 IBC/IRC with Massachusetts amendments.
  • One- and two-family homes follow the IRC chapters adopted into 780 CMR; larger buildings follow the IBC-based chapters.
  • The Stretch Energy Code (IECC with MA amendments) applies in most MA municipalities and is stricter on insulation, windows, and air sealing.
  • Electrical follows 527 CMR / the MA Electrical Code (NEC with amendments); plumbing and gas follow 248 CMR.

Reading a residential plan set

  • Sheet order: G (general/notes), A (architectural), S (structural), M/E/P (mechanical, electrical, plumbing).
  • A-101 is typically the first floor plan; A-2xx are elevations; A-3xx are sections; A-4xx are details.
  • Start with the legend and abbreviations sheet — every set defines its own symbols.
  • Dimensions are read outside-in: overall building, then wall openings, then interior partitions.

Key residential code numbers (IRC / 780 CMR)

  • Stairs: max 7¾" riser, min 10" tread, min 36" width (IRC R311.7).
  • Guardrails: required over 30" drops; balusters spaced so a 4" sphere can't pass (R312).
  • Ceiling height: min 7'-0" in habitable rooms (R305); basements often 6'-8" to beams/ducts.
  • Egress: every bedroom needs an emergency escape window — min 5.7 SF opening, max 44" sill height (R310).
  • Smoke alarms in every bedroom, outside sleeping areas, and every level; CO alarms near bedrooms (R314/R315).

Permits in Massachusetts

  • Most structural work, additions, decks, and finished basements need a building permit from your local building department.
  • Plans for new homes or major additions usually need a Massachusetts-registered architect or engineer's stamp.
  • Homeowners can pull permits for their own 1–2 family home, but electrical, plumbing, and gas work require licensed trades.
  • Always confirm with your local inspector — municipalities can add zoning and historic-district requirements on top of 780 CMR.

Answers are AI-generated guidance, not legal advice. Codes vary by municipality and change over time — your local building inspector and a licensed MA architect or engineer have the final word.
