Alignment Tools (Requires BCM Option)

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).
