+You can approximate the functionality of a digitizer arm using any robot arm, by reading the axis rotations and reconstructing the location of the end effector in 3D space. Typically, read-outs from a robot arm will be in [Euler Angles](https://en.wikipedia.org/wiki/Euler_angles).

 # Large Scale
 
-Add Dennis Shelden Dissertation content
 
+Beyond inspection in manufacturing contexts, Frank Gehry was the first architect to incorporate mechanical digitizing into the process of form making:

+The technical complexities behind this feat are documented thoroughly in Dennis Shelden's 2002 MIT Dissertation:

+The precursor to MIT's Stata Center, Gehry's 2000 Museum of Pop Culture in Seattle was the first to test translating this digitization workflow into full scale construction:
