Manual CAD Instruction

Recent Update: June 12, 2026

1. Overview

Manual CAD Files — As-Built CAD (Measured Existing Conditions)

Professionally hand-drafted 2D CAD documenting your building's measured existing conditions, derived from point-cloud / 3D-tour scan data. Drawings are produced to LOD 200 geometry with a layer structure mapped to both AIA NCS V7 (North America) and ISO 13567 (Europe / International), delivered as editable AutoCAD files (.dwg / .dxf) plus PDF — ready for your team to take straight into design or documentation.

Who it's for

Architects, contractors, surveyors, designers, and other building professionals who need an accurate, editable as-built base of a space as it stands today — without a manual measure-up.

Ceiling-mounted lights, diffusers, detectors and fans — these are part of the base Reflected Ceiling Plan

Door & Window Schedules

Adds door and window schedules — ID, size, type, swing — cross-referenced to the door / window tags on the plan, so every opening on the drawing has a matching schedule entry.

Delivered as: embedded on the Floor Plan's schedule sheet, plus standalone PDF + .xlsx + .csv files (one each for the door and window schedules) for further use. Schedules cross-reference the plan tags (D01, W01…).

Room Schedule

Adds a room schedule listing, per room: name, number, area, perimeter, ceiling height (CH), and floor finish.

Room names follow the Realsee standard room vocabulary

Delivered as: embedded on the Floor Plan's schedule sheet, plus a standalone PDF + .xlsx + .csv file. Includes per-floor subtotals and a project grand total.

4. Accuracy & Standards

Geometry — LOD 200. Drawings are produced to Level of Development 200: generalized elements with accurate size, shape, location, and orientation, suitable for design reference and documentation. Both capture devices below meet LOD 200.

Measured accuracy — by capture device.

Accuracy depends on the device used to capture the space. Under the USIBD Level of Accuracy (LOA) framework — which defines each level as a tolerance range at 95% confidence — the devices sit as follows:

Capture device	Rated accuracy	USIBD LOA band
Galois P4	±10 mm	within LOA30 (5–15 mm)
Galois M2	±20 mm	within LOA20 (15–50 mm)

These figures sit on the measured side of the USIBD framework — the accuracy of the captured data.

The represented side (the drawing itself) is controlled separately: drawn geometry is held to within ±15 mm of the point cloud, and the point-cloud reference layer in every .dwg lets you check the drawing against the scan yourself. Verifying accuracy against the building itself requires on-site reference measurements, which only a field team can take — if your project calls for formal verification, spot-check key dimensions on site against the drawing.

"Measured accuracy" is independent of display precision — an Imperial drawing can display to 1/4" while being measured to the tolerance above.

Layer standards — NCS V7 / ISO 13567. Layer naming follows the system that matches your region:

Imperial → AIA NCS V7 (U.S. National CAD Standard), the norm for North American reviewers and permitting.
Metric → ISO 13567, the European / international convention.

The two are mapped to each other, so the same content is organized consistently whichever system you choose.

When you order Manual CAD Files from Realsee, you're not getting a one-off drawing drawn to someone's personal habits. Every deliverable follows a documented standard that is mapped to nine established international and industry standards — the same standards your architects, contractors, and reviewers already work with. This page explains what those standards are, what each one governs, and — importantly — what "standards-compatible" does and doesn't mean.

The nine standards we map to

Different parts of a CAD drawing answer to different standards. Here's what governs what:

Standard	What it governs in your drawings
AIA NCS V7 (U.S. National CAD Standard)	Layer naming, sheet numbering, sheet sizes, title blocks, and overall drawing-set organization — for North America
ISO 13567	Layer naming for Europe and international projects
ISO 12006-2	The building-element classification behind the layer structure
ISO 128	Drafting conventions — line weights, line types, and views
AIA CAD Layer Guidelines / AIA E202	Layer-organization principles and the Level-of-Development framework
USIBD LOA v3.1 (U.S. Institute of Building Documentation)	Measured-accuracy levels — the tolerance band your drawing is held to
BIMForum LOD 2025	Level of Development — the geometric detail of the elements
Architectural Graphic Standards	Dimensioning conventions, abbreviations, and how doors, windows, stairs, and casework are drawn
NKBA	Standard representation of kitchen and bath fixtures

In addition, the layer classification is cross-mapped to Uniclass 2015 (UK), OmniClass (US), and CI/SfB (Northern Europe), so the same drawing can be understood across regional classification systems.

5. Units & Delivery

Your Unit selection drives more than number format — it cascades through dimensioning, sheet sizes, and layer organization.

Choose the system your downstream users and reviewers work in, and the rest follows automatically.

What the unit changes

	Metric (mm)	Imperial (ft-in)
AutoCAD units	Decimal	Architectural
Dimension format	2700	8'-10"
Display precision	Whole mm	1" / 1/4" / 1/8" / 1/16"
Area unit	m²	sf
Sheet-size series	ISO A (A0–A4)	ANSI / ARCH
Layer-naming system	ISO 13567-mapped	AIA NCS V7
Units note on sheet	"All dimensions in mm…"	"…in feet and inches…"

Which to choose

North America → Imperial + NCS V7.
Europe / Australia / International → Metric + ISO 13567.
When in doubt, match the system your architect, contractor, or authority works in — that's what the deliverable should align to.

Delivery time

Standard delivery is tiered by floor area. The times below are per drawing;

When you order more than one drawing type, multiply by the number selected (e.g. Floor Plan + RCP = the per-drawing time × 2).

Area	Per-drawing delivery (business days)
0 – 1,000 sqft	3 – 5
1,001 – 2,000 sqft	3 – 5
2,001 – 3,000 sqft	3 – 5
3,001 – 4,000 sqft	4 – 6
4,001 – 5,000 sqft	4 – 6
5,001 – 10,000 sqft	4 – 6
10,001 – 20,000 sqft	6 – 9
20,001 – 30,000 sqft	7 – 10

6. How It Works & Pricing

How to order

Start from a captured 3D tour / scan of your space.
Select your drawing types (Floor Plan, RCP) and any Floor Plan add-ons.
Choose your unit (Imperial / Metric) ,display precision and other configs.
Place the order — your editable CAD set is delivered within the stated turnaround.

How pricing works

Pricing is tied to floor area. Each drawing type has a base price per area tier; Add-ons are priced per tier on top of the Floor Plan.

RCP can be ordered on its own or bundled with a Floor Plan at a discounted bundle price.

Prices are shown in Credits.

7. Scope & Limitations

Scan-derived, not a field survey — Drawings are produced from point-cloud / 3D-tour scan data to the measured accuracy of the capture device, rather than a traditional field survey. Independent field verification is recommended before use for construction, permitting, or as-built records.
Obstructions & inferred geometry — Where areas are obstructed, inaccessible, or not captured (behind fixed objects, above ceilings, inside service rooms), geometry may be inferred. Inferred areas are noted in the drawing's General Notes so you can distinguish measured from inferred work.
Point-cloud reference — Each .dwg includes a point-cloud reference layer (orthographic, aligned to the drawing) for checking against the scan. It is a layer within the drawing, not a separate point-cloud dataset.
Out of scope — MEP engineering design, concealed services, and structural / load calculations are not included.
Coming soon — Interior elevations and sections are not yet available and will be released later.
