SLAM to CAD Workflow: Index Trimble MX60 & Navvis VLX
New Feature: SLAM to CAD workflow Indexing Mobile Mapping & SLAM Data (Trimble MX60 & Navvis VLX)
Undet Indexer now supports high-performance indexing for Mobile Mapping Systems (MMS) and SLAM (Simultaneous Localization and Mapping) scanners. This update specifically streamlines the workflow for Trimble MX60 and Navvis VLX users, allowing you to bridge the gap between massive reality capture datasets and actionable CAD/BIM environments.
Whether you are dealing with large-scale urban mapping or complex indoor SLAM trajectories, Undet ensures your point cloud remains lightweight and navigable without losing the visual context of your panoramas.
Created Undet projects can be used with all Undet solutions:
Step 1: Select Project Type
Launch the Undet Indexer and select the project type that corresponds to your data source. Choosing the correct type ensures the software optimizes the density and coordinate scaling for mobile or terrestrial datasets.
Step 2: Import Scan Data
You can import files from your local PC or network drive. Undet supports a wide array of industry-standard formats:
Common Formats: *.E57, *.LAS, *.LAZ, *.RCP/RCS, *.PTS, *.PTX
Manufacturer Specific: *.FLS, *.ZFS, *.FPR, *.LSPROJ, *.FWS, *.CL3, *.CLR, *.RSP
ASCII: NEZ (X,Y,Z/i/RGB) and custom *.TXT formats.
Step 3: Advanced Settings & SLAM/MMS Optimization
Before clicking [Create Project], configure your settings to ensure the best performance in your downstream CAD application (AutoCAD, Revit, or BricsCAD).
| Feature | Description |
| Undet for AutoCAD | Creates additional files necessary for the AutoCAD plug-in. |
| Undet for Revit | Generates an *.RCP file for native Revit compatibility. |
| Undet Browser Project | Essential for SLAM/MMS. Links 3D point clouds with 360° panoramic views. |
| Remove Duplicates (2mm) | Highly Recommended. SLAM data often has high overlap. This filters redundant points to ensure a “lighter” cloud and smoother CAD performance. |
| Custom Offset | Manually align your SLAM trajectory or MMS data to specific project coordinates. |
Step 4: Integrating Trimble MX60 & Navvis VLX Panoramas
This is the core advantage for Mobile Mapping and SLAM users. You can now sync high-resolution imagery with your point cloud for a “Street View” experience within your CAD software.
-
Enable the Select panorma folder and Radius.
-
Select the Trimble MX60 or Navvis VLX panorama folder.
-
Note: The selected folder must contain the panoramic image files and the corresponding .csv file (which contains the trajectory/camera positioning data).
-
Define Selection Radius: Adjust the Select radius based on your environment to optimize your SLAM to CAD workflow speed:
-
10 Meters: Recommended for indoor SLAM scans (e.g., Navvis VLX).
-
30 Meters: Ideal for outdoor mobile mapping (e.g., Trimble MX60).
-
Pro Tip: Reducing this radius significantly decreases indexing time.
-
Why this matters for SLAM users: Unlike traditional static scans, SLAM and Mobile Mapping data rely on a continuous trajectory. By importing the CSV reference, Undet correctly places every panorama along your path, providing 100% visual coverage of your site.
Step 5: Finalizing the Project
Click [Create Project]. Once the indexing is complete, Undet will generate:
-
An .IPCP project file.
-
A folder with the same name containing the indexed data.
Important: These two items must always be kept in the same directory to function correctly.
Next Step: Visualizing Your Data
Now that you have successfully indexed your SLAM or Mobile Mapping data, the next step in the SLAM to CAD workflow is to open your project in the Undet Browser.
This will allow you to navigate your Navvis VLX or Trimble MX60 trajectories using high-resolution 360° panoramas and extract precise measurements directly into your CAD environment.
