How to manually align models with point clouds

Modified on Mon, 29 Jan 2024 at 03:00 PM

If models and point clouds originate from different software packages, they might have different coordinate systems. In this case, you must align models after the import.

  • Import your file with Offset Origin. This moves the bounding-box center of your model to the center of the grid. Make sure your model doesn't contain any outliers or a legend, otherwise the relevant part of your model won't appear near the origin.
  • Select your model in the Object List and press F to focus on it. 
  • Select the active camera in the Object List and switch to the orthographic view from Object Inspector > Object Attributes
  • Activate the translation manipulator  from the toolbar. Left-click & drag handles to move the model to its correct location. Optionally switch to predefined views to visually verify the alignment.
  • If you need to rotate your model, activate the rotation manipulator  from the toolbar, and adjust the rotation for optimal alignment with the point cloud.
