@DrewDowling  There is no need to use geodatabase 'subtypes' - they might add unnecessary complexity. Subtypes are only needed when you want to apply different topology rules and/or different attribute rules (behaviors). To use a point as 'constrained' during LSA (Least Squares Adjustment) just set it as 'XYZ Constrained': Each control point belongs to a different class, which usually infers different accuracy: 1. Add a field called 'PointType' or 'class' and specify the class 2. Add an Attribute Rule calculation and assign a different 'XY Accuracy' for each class. That accuracy is used in LSA to weight the 'measuremetns' which are the XYZ coordinates. If you want to prevent a point from moving - set the 'IsFixed' field to 'Yes' (1). To learn more about LSA see help documentation. If you want to make sure the XY(z) coordinates match the geometry import some the shipped Attribute Rules - see the help documentation.   The key to a good adjustment is good (input) measurements. For example - if all the measurements are inversed (from geometry) it makes no sense to expect LSA to converge to a better solution. Amir ... View more
