The system will prompt you to select the right units to import data Import scan data sets by following the path “File/import/Point Clouds” TIP: You can view or hide the CAD or Scan object by hovering over the icon on the tree and clicking the middle mouse button TIP: by default, scan will be imported in millimeters, the units can be changed after TIP: You can also import polygon objects; the system will automatically recognize them as test data

TIP: This menu will only work if you have imported both the reference and data objects TIP: most function found in text menu can be found as buttons in the menu interface TIP: the “All” option to select any item on the three, or pick “specific” to narrow down your selection options

A new “Best-fit to ref 1” icon will appear on the tree under Data Alignments Click on the right to finalize the dialog, both objects are now aligned TIP: to simplify your task, match the view of each window so the objects look the same, this will make it easier to find matching pairs of points TIP: the “All” option to select any item on the three, or pick “specific” to narrow down your selection options TIP: depending on the geometry, you may pick automatic instead of point pairs to skip the matching process.
