In our previous article, we discussed methods in SpatialAnalyzer (SA) to align an instrument in order to compare measurements of an actual part to a nominal or ideal part. However, this only scratches the surface of SA's alignment tools. Once you have more than one instrument station in a job, each new station must be aligned with every other station in order to create a network of measurements. SA provides three options for creating a network alignment:

• Best-Fit
• Bundle Adjustment
• Unified Spatial Metrology Network (USMN)
