Laserscanning Architecture uses PointCab Origins in AutoCAD Architecture

The company Laser Scanning Architecture used the FARO 3D laser scanner for the three-dimensional acquisition of a historic commercial hall. The 3D data created was evaluated using AutoCAD Architecture and PointCab Origins. The scan data was analyzed in both photo mode and pixel mode using FARO Scene software. In the model, analyses and geometric allowances were performed in colored panoramic views. Perspectives could be freely selected and partial areas of the model could be hidden as desired.

Using PointCab Origins, a 2D analysis was realized in AutoCAD Architecture. For this purpose, orthographic 2D views of the existing structure were created from any position in the model using PointCab Origins. This laid the foundation for efficient replanning. The advantages were: orthographic 2D images of the inventory, as well as freely selectable positions in the scan. The inventory could be quickly captured in detail (cornices, stone formats, etc.). The resulting highly accurate dimensioning, formed the basis for efficient redesign, including overdrawing of component edges. PointCab Origins results were used to create plans, elevations, sections and 3D BIM models. Images could be extracted from the point cloud. The client was able to quickly view and use the information thanks to the web export.

About Laser Scanning Architecture

As a formerly classic architectural office, we specialized in 3D laser scanning in 2010. Since then, the demand has increased so much that we are now only active in 3D surveying. Managing director Johannes Rechenbach has a working experience of more than 30 years as a freelance architect and has been running his own architectural office in Hannover for 20 years.

During this time, we have learned many times that a thorough survey of the existing building is always the basis for a successful remodeling project. The precise laser scanning therefore offers the perfect basis for all projects of building in existing contexts. https://www.laser-scanning-architecture.com

Refurbishment of a listed industrial building in Magdeburg

3D laser scanning was used as a surveying method for the listed renovation of an old industrial building in Magdeburg. As part of the renovation and conversion work, 22 loft apartments are to be created in the complex. In order to renovate the façade in accordance with the preservation order during the conversion work, detailed, highly accurate plans of the façade to scale are required. Due to the limited space available, the 17 m high facade can only be mapped using a non-contact measuring method.

The smallest of the three facades, the east facade, has several facade jumps and sloping facade parts, which increased the effort of surveying and evaluation.  With the help of laser scanning, the facade details, such as window openings and wall protrusions, could be captured with high accuracy.

Orthophotos were automatically generated from the laser scanning survey results using PointCab Origins. Using the true-to-scale PointCab Origins images, the data was imported into Geograf within an hour. This resulted in detailed orthophotos and structured, digital 2D plans of the facades, including the cracks in the east facade. Modeling can now be carried out in the generated views and sections of the 3D CAD model, which simplifies planning for the renovation and conversion work.

The facts again at a glance: The three facades of the building complex were captured by laser scanner. The data was evaluated with PointCab Origins and Geograf at a scale of 1:50. A total of 25 laser scanner locations were used to measure the 1,720 m² of the facade. Only one employee was needed for the survey, which took only 5 hours. One of the advantages of PointCab Origins was the fast generation of the othophotos. Within one hour, 3 GB of data could be processed. This resulted in true-to-scale and detailed images. Reading in and further processing of the data in the CAD system Geograf was possible without any problems. Thanks to the quickly generated Othofotos, the evaluation in Geograf was a piece of cake. In total, the project was completed within 35 working hours from the first scan.

As-Built Documentation of an Old House: Why a Complete 3D Laser Scan Was Essential

blank

An old residential building in a village in the Swiss canton of Ticino lacked reliable, up-to-date building plans. To prepare renovation and restoration work, the engineering firm Geomatica Righitto (Lugano, Switzerland) was commissioned to do a full 3D as-built documentation.

Traditional plans were missing or outdated, and the building required precise measurements to support planning in CAD and BIM software.

Missing Plans, Irregular Geometry, and the Need for Precision

Interior of kitchen in Ticino. Slight deviations are visible.

Older buildings rarely follow perfectly straight lines or standardized geometries. Over decades – or even centuries – walls may shift, floors may sag, and angles deviate from 90 degrees.

This means: assumptions based on symmetry or “standard” geometry can be highly misleading.

For renovation work, especially structural or restorative interventions, accurate data is crucial. Because no reliable plans existed for this house and its geometry was visibly irregular, a precise and complete measurement was essential, making 3D laser scanning the ideal method.

Survey: Faro Photon 120, Faro Scene, and Efficient On-Site Work

blank

Geomatica Righitto used a FARO Photon 120 laser scanner to capture the entire building, including:

  • three façades,
  • the basement,
  • the roof,
  • and all four floors.

In total:

  • 29 scans,
  • 6 hours on site,
  • 3 survey specialists.

All scans were registered and merged in FARO Scene, ensuring correct alignment and a unified, consistent point cloud.

This point cloud became the complete digital representation of the building, including all the irregularities typical of older structures.

Point clouds are for engineers, plans for architects. PointCab Origins is the fastest connection between them.

Processing the Point Cloud: Fast Extraction of Plans and Sections

Layout and facade view in PointCab Origins

Once the unified point cloud was ready, Geomatica Righitto used PointCab Origins to extract essential architectural outputs:

  • 4 floor plans
  • 3 façade plans
  • 20 building sections
  • Orthophotos for façades and interior walls

These automated extractions significantly reduced manual drafting work.
 The final drawings — both as-built documentation and renovation plans — were delivered in a CAD/BIM-ready format for use in Archicad.

The entire processing workflow, including preparation for delivery, took about 8 hours.

What This Case Study Demonstrates

This project shows how even older buildings with irregular geometry and missing documentation can be comprehensively captured. Old buildings are rarely dimensionally perfect, but laser scanning captures reality exactly as it is, and the resulting point cloud becomes a trusted digital baseline.

The combination of FARO Photon 120, FARO Scene, and PointCab Origins enabled Geomatica Righitto to create reliable plans quickly –  giving architects and engineers the confidence they need to design renovations and restoration work effectively.

Surveying 12,000 m² of Inhabited Floor Space:
Why a Complete 3D As-Built Survey Was Needed

blank

The project involved surveying more than 12,000 m² of inhabited floor space, including a hotel, a municipal theatre, offices and residential units.

For such mixed-use buildings, reliable and up-to-date as-built plans are essential — especially when fire-protection documentation is required.
Because existing plans were incomplete and the building was in active daily use, a full digital survey became the most efficient and accurate solution.

The Challenge: Surveying a Large, Inhabited Mixed-Use Building

Hotel Lobby

Inhabited buildings present extra challenges compared to empty or unused structures:

  • Continuous operation: Hotel guests, office staff and residents could not be disturbed.
  • Mixed layouts: Hotels, theatres, offices and residential spaces each have different room structures, escape routes and technical areas.
  • Complex circulation: Theatre back-of-house zones, technical rooms and varying ceiling heights complicate manual measurement.
  • Large total area: Over 12,000 m² had to be captured consistently across several building sections and levels.

To meet these challenges, the team selected a high-precision, fast and non-intrusive method: 3D laser scanning.

How the Survey Was Completed: FAST Laser Scanning With Only Two People

blank

The surveying was executed by Faschang Service & Management GmbH, who used a FARO Focus3D laser scanner to capture every part of the building.
Despite the size and complexity, the entire scanning process was completed:

  • in 45 hours,
  • using just two employees.

This shows the efficiency of laser scanning in inhabited environments: the scanner captures geometry quickly, quietly and with minimal disruption to regular building operations.

Point Cloud Evaluation in PointCab Origins: From Scan to Plans

blank

Once the point cloud was created, it was processed in PointCab Origins, where essential deliverables were generated automatically:

  • floor plans,
  • site plans
  • sections
  • orthophotos.

Using these true-to-scale orthophotos, the team produced the required as-built drawings and fire-protection plans in AutoCAD.

Because all data originated from the point cloud, the resulting plans were consistent, accurate and based on the current state of the entire 12,000 m² complex.

The perfect software solution for efficient creation of orthophotos and as-built plans.

Digital Data for Future Use: One Scan, Many Applications

A major advantage of the workflow is that the complete point cloud was stored as a digital record.
This proved useful later: when façade drawings were needed for extension planning, the team was able to generate them directly from the existing scan — without additional site visits.
One scan created a long-term data resource that can support fire protection, renovation, design updates or further documentation tasks.
