OrthoGraph I
The new dimension of building survey

The most versatile technology for building survey

Forget the clumsy hand drawn sketches and outdated, unreliable floor plans: turn your tablet or smartphone into a powerful working tool with OrthoGraph I.

Conduct a complete building survey with the most versatile technology: by using OrthoGraph I and your iOS or Android mobile device, you can map out and measure buildings and architectural spaces quickly and accurately. Your iOS or Android smart device utilizes all the benefits of the multi-touch screen that is large enough to work with, while supports the BIM concept in all detail.

It does not matter if you work on small rooms as a carpenter or large office buildings as a member of a building surveyor team, OrthoGraph performs well in both situations.

Main features of OrthoGraph


Sketch & Tap

Forget unreliable, outdated sketches. Use your iOS or Android mobile device and sketch your floor plan the way you would do with pencil and paper: OrthoGraph I creates walls automatically from your lines. Merge rooms easily together, simply move them besides each other and they will snap to their proper position.


Measure as you go

Measure everything as you go: walls, diagonals, openings, ceiling height, or even objects, by snapping measurements directly into your drawing, via Bluetooth® from your compatible Leica laser distance meter. You won't need another colleague to help with survey anymore, so you can move faster.

Reports, calculations

Use photos, annotations and custom parameters – the program allows you to document every detail of the building you work on. Get calculations on surface values, volume, and perimeter on site. Email a complete building documentation from the scene to your desktop, to your clients or colleagues.

CAD and BIM compatibility

By using OrthoGraph I, you build BIM models, which can be exported into the main large scale desktop file formats - IFC, DXF - with just a simple touch, just to be emailed to your desktop or even to your clients. Save yourself from the long hours of manually loading your survey results into your CAD software - as OrthoGraph I is compatible with most CAD platforms, tedious redrawing is history.

3D walkthrough

See your floor plan in 3D! 3D walkthrough is a great function to show your projects to your clients in a realistic form. Furthermore, it helps you to check all details in your floor plan, so you can see immediately, if you missed something.
