From A Walk-Through To A CAD Model
ScanTo3D by Opal AI tackles a slow, expensive problem: getting an accurate digital model of a real building. Instead of hiring a surveyor or wrangling a point cloud on a desktop, you walk through a space with a LiDAR-equipped phone or tablet and the app reconstructs it into a 2D floor plan and a 3D CAD model in real time. The output is meant to be measured against and worked with, not just looked at, which is what makes it useful to professionals rather than hobbyists.
Opal AI describes its broader focus as spatial AI, turning visual and spatial data into actionable models. ScanTo3D is the building-scanning product within that family, aimed squarely at people who need dimensions, layouts, and structure they can trust.
How It Works
ScanTo3D relies on LiDAR depth sensing combined with Opal AI's reconstruction algorithms. As you move through rooms, the app captures the geometry and stitches it into a coherent model on the fly, detecting walls, openings, and the overall layout. The result is a floor plan you can read and a 3D representation you can take into downstream tools. Because it processes spatially as you scan, you get fast feedback on coverage instead of discovering gaps back at the desk.
That real-time loop is the difference-maker. With traditional surveying you capture data on site and only learn whether it is complete once it has been processed back at the office, which can mean a costly return trip. Here, you watch the model build as you walk, so you notice a missed corner or an under-scanned room while you are still standing in it. The captured geometry is the same data downstream tools care about, which is why the output drops into CAD and BIM workflows rather than living as a one-off image.
Standout Features
Real-Time 2D And 3D Output
The app generates both a flat floor plan and a 3D model from the same walk-through, so you leave a site with documentation rather than raw data to process later.
Scan To BIM
Beyond the mobile app, Opal AI offers Scan to BIM, converting point cloud data into detailed Building Information Models. That bridges field capture to the structured models architecture and construction teams actually build with.
Spatial AI Platform
ScanTo3D sits alongside other Opal AI tools for infrastructure and risk analysis, reflecting a company built around 3D reconstruction and deep learning rather than a single one-off app.
Who It Is For
ScanTo3D is built for professionals who deal with physical spaces. The clearest fits include:
- Real estate and property teams documenting listings and producing accurate floor plans without booking a surveyor.
- Insurance adjusters capturing a property's layout and dimensions for claims, inspections, and assessments.
- Architects and contractors who need a fast first pass on as-built conditions before detailed design work begins.
- BIM specialists turning field captures into structured models the rest of the project can build on.
- Facilities, utilities, and planning teams that maintain or assess existing buildings and infrastructure.
It is less suited to creating decorative 3D art or game props, since the whole point is measurable, structural accuracy rather than visual flourish.
Credibility And Partnerships
Opal AI lists relationships that signal it is more than a lightweight app, including work as a Google Cloud and NVIDIA partner and support tied to NASA and NSF programs, plus academic affiliations. For buyers in regulated or high-stakes fields like insurance and construction, that kind of backing is reassuring when accuracy carries real consequences.
Pricing
Opal AI does not publish a simple consumer price list on its main pages, and enterprise spatial tools are commonly sold through direct contact or tiered plans rather than a single sticker price. If you are evaluating ScanTo3D for a team, the practical move is to download the app to test capture quality and reach out to Opal AI for plan and volume pricing that fits your use case. For organizations running many scans across multiple sites, volume and seat-based arrangements tend to make more sense than a flat per-scan fee, which is another reason a quick conversation beats guessing from a public number.
Verdict
ScanTo3D is a focused, professional answer to a real bottleneck in how spaces get documented. Turning a LiDAR walk-through into a floor plan and CAD model on the spot saves time that surveying and manual modeling normally eat up. The trade-off is the obvious one: you need a LiDAR-capable device, and results depend on careful, complete capture. For real estate, insurance, and AEC teams that need dependable layouts fast, it earns its place in the toolkit.
