Using Six-Point Calibration

This method adjusts the position of a product or resource based on the measurement of points on three mutually orthogonal planes. This calibration method should be used when the product has three mutually orthogonal planar surfaces, and does not have at least three point-like features that can be easily identified and measured.

Before you begin: You must have:
  • A product or resource with a tag group containing at least 6 tag points representing the simulation tag points that are to be adjusted
  • A tag group containing 6 tag points representing points that are uploaded from the measurement of a real world product.
Note: Clicking Undo while this command is active causes the command to cancel.
  1. Click 6 Point Calibration .
  2. Select the product/resource whose position you wish to adjust.
  3. Select six unique tag points located (attached) on this item.
    The six tag points should define the simulation points to be adjusted. These six points must define three different mutually orthogonal planes on the product: three points on the first plane, two points on the second plane and one point on the remaining plane. Note that order of plane definition is important.

  4. Once the first 6 tag points have been indicated, select 6 different unique tag points defining the desired (Goal) position. These 6 tag points are uploaded by measuring points on 3 mutually orthogonal planes of the product in REAL world.
  5. Once you have selected the second set of tag points, the product/resource is moved in an attempt to get the planes defined by the first set of tag points to align with the planes defined by the second set of tag points.

    Not only is the order that the planes are defined important, but also the direction of planes is critical. Even though each set of six points can lie anywhere on the 3 planes, the order the points are selected determine the plane directions. The 3 points defining the first plane should be selected in the corresponding clock-wise or counter clock-wise direction. The two points defining the second plane must be selected so the vector from the first to second points is in the same general direction.

    If the calibration is successful, the product/resource is moved.

    If it is not successful, the command terminates with the message Points are Collinear – Calibration Failed. You can undo the calibration immediately after it is done by selecting the Undo command.
