AutoCAD R12 ASCII, a separate layer per tool, scaled in metres – opens straight in AutoCAD.
Measure workspace in the browser
Your delivered roof model becomes a measuring workspace – not a dead file.
Open your project in the browser and measure it yourself: the real usable net PV area with exclusion zones subtracted live, roof pitch in degrees, heights and running metres. From a real project: 179.72 m² gross − 12.37 m² exclusions = 167.35 m² net. Export to DXF, CSV, PDF and PNG included.

The subtraction, live
You draw an exclusion zone – the net area recalculates instantly.
True 2D-polygon overlap instead of crude subtraction. Mark a chimney, dormer or skylight and Voxelia corrects the usable module area in real time – every exclusion zone gets its own label. No competitor delivers this live net figure; everyone else reports only the gross area.

This isn’t a video. Measure it yourself now – in your browser.
Rotate a real delivered model, set two points, read off the distance. No account, no download. This is exactly how you later open your own project – except there your measurements stay saved on the project. Loads GLB, GLTF and DAE directly – standards-based, no black box.

A full toolbox, not two buttons
Nine measuring tools – plus the net area no one else computes.
The competition stops at distance and area, maybe slope. Voxelia ships a real measuring suite – every tool framed as an outcome from your day-to-day work.

How you work
Three steps from delivered model to exported hand-off.
Open your project
Open your delivered roof model in the dashboard, right in the browser, with no install.
Measure it yourself
Net PV area, pitch, heights and running metres with the nine tools. Exclusion zones are subtracted live, and your measurements stay saved on the project.
Export & hand off
DXF for CAD, CSV for PV*SOL, a PDF report for the file, PNG with a scale badge. Question changed? Reopen the project and re-measure – no new order.
Trust, not claims
The tool tells you how far you can trust the number.
No spec war over centimetres. Voxelia shows at every moment how reliable the dimension is – across three honest tiers. A tool that honestly shows “Visual only” is more credible than one that always claims certainty.
01Verified
The scale comes from Voxelia’s delivered handoff.
02Calibrated
You set the scale using a known 2-point reference.
03Visual only
An honest badge when the model is unscaled – no faked precision.
True 2D-polygon overlap instead of naive subtraction · units m or cm · adjustable decimals · scale burned into every PNG and PDF export.
Voxelia replaces nothing – it feeds
Already using AutoCAD and PV*SOL? Voxelia is the step before.
I already use AutoCAD and PV*SOL – why measure here?
Voxelia doesn’t replace AutoCAD – it feeds it. Measure in the browser without a CAD seat, export to DXF (a layer per tool) and PV*SOL-ready CSV. No CAD seat needed just to grab a roof edge, no waiting for the one colleague with a licence. Voxelia is the step before your CAD/PV*SOL, not a replacement.
My deliverable is a CAD file from the surveyor – why a workspace?
A CAD file answers one question. A measurable model answers every question that comes later: new exclusion zone? Recompute the net area live. Need a new height? Measure it yourself in the browser – no new order, no new site visit.
Is this actually accurate? Can I trust the numbers?
The tool shows at every moment how reliable the dimension is: Verified (scale from Voxelia’s delivered handoff), Calibrated (a 2-point reference of known length) or Visual-only (an honest badge when unscaled). Exclusion zones are subtracted by true 2D-polygon overlap, and the scale is burned into every PNG and PDF export.
Do I need to install software or train my team?
No. It runs entirely in the browser, nothing to set up, no CAD or PV*SOL licence. GLB, GLTF and DAE load directly – standards-based, no black box. Try it on the sample roof before you sign up.
Do my measurements persist, or do I lose my work?
Your measurements stay saved on the delivered project – reopen it and everything is there, including pins (open / in review / resolved) and saved views. For the permanent hand-off you additionally export DXF, CSV and a PDF report.
What does it cost? Do I need a subscription?
Check your first project free on your own data set – no subscription, no card. After that it’s a transparent per-project price: check a data set from €45. The measurable workspace comes with every delivered model, with no hidden software or cloud fees.
Every model stays a tool
The question changes – your model stays. Re-measure, don’t re-order.
Never re-order
New exclusion zone? Recompute the net area live. A height nobody captured? Grab it yourself in the browser – no new site visit, no new CAD order.
Your data is yours
Open, portable formats: DXF, CSV, PDF, PNG and standard model formats GLB, GLTF, DAE – exportable any time, no hostage data model.
GLBGLTFDAEDXFCSVPDFPNG
Traceable across the team
Mark, review, tick off: pins with status (open / in review / resolved) and saved views stay on the project, for the whole team.
Once your model is a measurable, exportable workspace, going back to flat photos feels like a downgrade.
For which job?

Frequently asked
Answers before you ask.
How can I measure a PV area in the browser?
You open your delivered 3D roof model in the Voxelia dashboard and draw the roof surface as a polygon. Voxelia computes the area in m² and subtracts marked exclusion zones such as chimney, dormer and skylight live, by true 2D-polygon overlap – you get the usable net PV area, with no CAD or PV*SOL licence.
Can I measure a roof area without CAD?
Yes. The measuring workspace runs entirely in the browser, with no install and no CAD licence. You measure distances, areas, heights and running metres directly on the model and export the result as DXF (opens in AutoCAD), CSV (PV*SOL-ready), a PDF report or PNG.
How do I measure roof pitch from drone imagery in degrees?
With the Slope tool you read roof pitch per facet directly off the model – the result appears in degrees. That gives you layout, yield forecast and the right minimum pitch for the covering, without climbing the roof.
How accurate is the measurement and how is scale set?
Voxelia shows scale confidence across three tiers: Verified (scale from the delivered handoff pipeline), Calibrated (you set scale via a known 2-point reference) and Visual-only (an honest badge when the model is unscaled). The scale is burned into every PNG and PDF export, with a disclaimer in the report.
Which formats can I export?
Four hand-off-ready artifacts: DXF (AutoCAD R12 ASCII, a separate layer per tool, scaled in metres), CSV (semicolon-delimited, prepared for PV*SOL), a PDF report (with logo, viewport screenshot, measurement table and scale disclaimer) and a PNG screenshot with a burned-in scale badge.
Do I need a PV*SOL or AutoCAD licence?
No. To measure in the browser you need neither a PV*SOL nor an AutoCAD licence. Voxelia is the step before: you measure licence-free and hand the result to your CAD as DXF and to your PV design tool as CSV.
Which model formats are loaded?
The measuring workspace loads GLB, GLTF and DAE directly in the browser – standards-based formats, no black box. That keeps the deliverable verifiable for surveyors and technical users too.
Do my measurements, pins and views stay saved?
Yes. In your delivered project, measurements, pins (status open / in review / resolved) and saved views stay attached to the project – reopen it and keep working. For the permanent hand-off you additionally export DXF, CSV and PDF.
Roof images in → measurable model out
Your next roof doesn’t have to be a dead file.
Others deliver a file you re-measure elsewhere. Voxelia delivers a workspace that answers every later question – and goes back out as DXF, CSV and PDF.
