Solar CAD and DXF Export for Rooftop Layouts

The roof plan and the PV layout from the RAYVO 3D Design Studio export as a DXF drawing. It is true to scale in metres, lines up with north, and puts every kind of object on its own layer, so structural and electrical consultants can work on it in AutoCAD, BricsCAD, LibreCAD or DraftSight without redrawing the site.

Capabilities

What it does, how, and what you get

Each capability below says what it does, how it is worked out, what it produces and why it matters to installers and EPC companies.

01

True scale, true north

What it does
A plan that matches the site.
How it works
Coordinates in metres, X to the east and Y to the north, with the origin at the site centre, and the drawing units set to metres in the file header.
What you get
A plan you can overlay on a site survey or a structural drawing.
Why it matters
Consultants can measure directly on it, without rescaling.
02

One layer per kind of object

What it does
Organised layers for CAD work.
How it works
Roofs, parapets (drawn as an inner line), rooftop obstructions, trees, neighbouring buildings, PV tables, individual modules, labels and the north arrow each sit on their own named, coloured layer.
What you get
Layers you can switch off, freeze or recolour like any other drawing.
Why it matters
A structural engineer can hide the modules and keep the tables; an electrician can do the opposite.
03

Every module, not just the table

What it does
Module rectangles inside each table.
How it works
Each table is split into its rows and columns of modules with the same gaps the studio uses.
What you get
Exact module positions for clamps, walkways and cable routes.
Why it matters
Clamp and rail positions are set by the module edges.
04

Labels that carry the design

What it does
Text that explains the drawing.
How it works
Roof labels with type, pitch, height and parapet height; obstruction labels with height; table labels with module count, tilt and facing; a title block with site, capacity, module and date.
What you get
A plan that can be read without the 3D model.
Why it matters
The drawing travels to people who never open the studio.
05

Opens everywhere

What it does
A format every CAD program reads.
How it works
AutoCAD R12 ASCII DXF with lines, polylines, circles and text only.
What you get
A file that opens in AutoCAD, BricsCAD, LibreCAD, DraftSight and most CAD viewers.
Why it matters
No converter, plug-in or special version needed.

How it works

Four steps on one design

  1. 1

    Design in 3D

    Roof, obstructions and the PV layout.

  2. 2

    Open Drawings

    The plan is built from the current design.

  3. 3

    Download DXF

    One file, layered, in metres.

  4. 4

    Work in CAD

    Structure, cable routes and approvals on the same plan.

FAQ

Solar CAD / DXF Export questions

Any program that reads DXF, including AutoCAD, BricsCAD, LibreCAD and DraftSight. It is written in the R12 format, which every version still opens.

Yes. It is in metres, true to scale, with X to the east and Y to the north from the site centre.

The DXF is the roof plan and layout. The single line diagram downloads separately as SVG or an A3 PDF.

Not today. RAYVO exports DXF; roofs are drawn in the studio over satellite imagery.
