You may need to align your scans and the BIM model if they are not in the same coordinate system.

  • In the 3D View, select the Manual Alignment Tool.
  • Select the reference data and the one to be aligned. You may want to align the BIM model to the scans or vice versa.
  • During the alignment process, navigation in the scene can be in Scan mode (3D RGB or 3D Surface) or in 3D Naviga-tion mode.
  • Pick a pivot point on your data ‘to align’.
    • In this example, the data ‘to align’ is the BIM model.
  • Align this pivot point to the same point in your scan data by using the Translation tool.
    • You may select a scan position and the Surface display mode to get more accurate visualization.
    • You can also play with the transparency levels for both the scans and the BIM model.
  • For both the translation and the rotations, you can put your mouse in the text field, enter a value or use your mouse wheel to adjust.
    • Using CTRL + Wheel, you will adjust by steps of +/- 10, with ALT + Wheel, steps of +/- 0.1, SHIFT + Wheel, steps of +/- 0.01.
  • Once the translation is done, adjust the rotation to align the model to your scans.
    • You may select various scan positions to adjust this rotation.
  • Once you are satisfied with the alignment, click on ‘Apply’ to save it.
  • If you have aligned the scans to the BIM, this transformation will be applied when downloading and exporting your scans as a point cloud (RCP, RCS, E57).
