What is sizeless?
Sizeless provides an AI-powered workflow for civil engineering that converts smartphone video of open trenches and house connections into precise 3D digital twins. Using an iPhone Pro, field technicians capture standardized video on-site, which is then processed by algorithms developed at ETH Zurich to generate centimeter-accurate 3D point clouds. These point clouds are automatically transformed into industry-standard 2D CAD as-built plans (DWG/DXF) and 3D BIM/GIS models, ready for immediate use in existing documentation and planning tools. The solution eliminates the need for separate surveying appointments, manual sketches, and specialized hardware, enabling faster backfill of trenches, audit-proof documentation, and increased project throughput for network operators and civil engineering teams.
Pros & Cons
Pros
- Accelerates construction timeline and billing by enabling immediate trench backfill
- No need for separate surveying appointments or special hardware, only an iPhone Pro
- Produces audit-proof, GIS-ready documentation that reduces manual errors and data silos
Cons
- Requires an iPhone Pro, limiting use on teams without compatible Apple devices
- Focused on open trenches and house connections, not general-purpose 3D scanning

sizeless FAQ
How does sizeless eliminate the need for separate surveying appointments?
Sizeless uses an iPhone Pro to capture standardized video of open trenches and house connections, which its AI algorithms process into centimeter-accurate 3D point clouds and CAD plans. This on-site capture replaces the need for a separate surveying visit, allowing field technicians to document and backfill trenches immediately.
How does sizeless compare to Matterport for civil engineering trench documentation?
Unlike Matterport, which focuses on general indoor and property scanning, sizeless is purpose-built for open trenches and house connections in civil engineering. Sizeless converts smartphone video into precise 2D CAD and 3D BIM models, while Matterport typically requires specialized cameras and produces different output formats not tailored to trench workflows.
Which teams benefit most from adopting sizeless?
Civil engineering teams, network operators, and field management crews that regularly document open trenches and house connections benefit most from sizeless. It accelerates backfill and billing by eliminating manual sketches and separate surveying appointments.
How is sizeless priced?
Sizeless is a paid product with no permanently free tier. The pricing model is designed for professional teams that need ongoing access to its AI-powered trench-to-CAD workflow.
Can sizeless generate both 2D CAD and 3D BIM models from the same video capture?
Yes, sizeless automatically transforms the same smartphone video into both industry-standard 2D CAD as-built plans in DWG/DXF format and 3D BIM/GIS models. This dual output supports immediate use in existing documentation and planning tools.
Does sizeless integrate with existing documentation and planning tools?
Yes, sizeless generates standard DWG/DXF and BIM/GIS model files that are ready for immediate use in existing documentation and planning tools. This integration reduces data silos and manual errors in civil engineering workflows.
Why does sizeless require an iPhone Pro instead of other smartphones?
Sizeless relies on the specific camera and sensor capabilities of the iPhone Pro to capture standardized video that its ETH Zurich-developed algorithms can process into centimeter-accurate 3D point clouds. This hardware requirement ensures the precision needed for audit-proof trench documentation.
