#### Math Process of the Legacy (I,J,K, X,Y,Z) RMEAS mode

This mode controls I, J, K, X,Y, Z (T) and therefore works well with 3d RMEAS features like circles with sample hits.

Using the numerical values taken from the example features in the table below, follow these steps to understand how RMEAS/LEGACY (I,J,K, X,Y,Z) functions.

1. Create a coordinate system (translation matrix) given the nominal RMEAS feature XYZ IJK.

2. Move the nominal Auto Feature XYZ and IJK into the RMEAS coordinate system.

3. Create a new coordinate system given the actual RMEAS feature XYZ IJK.

4. Now move the translated Auto Feature XYZ and IJK back into the PART coordinate system using the new RMEAS coordinate system.

5. Use the new nominal XYZ and IJK to measure the Auto Feature.

Example Feature | XYZ | IJK
Nominal RMEAS feature (circle): | 0,0,2 | 0,0,1
Nominal Auto Feature (circle): | 2,1,0 | .7071,0,.7071
Actual RMEAS feature: | -1,0,1 | -.7071,0,.7071
New Nominal Auto Feature: | 1.8284,1,1 | 0,0,1
