### Using STP Files

Each CMM uses machine-specific parameters for temperature compensation for each axis, such as thermal coefficients and sensor assignments. These parameters, along with embedded code that tells PC-DMIS if the file is a structural or linear compensation file, are stored inside special STP files (named for the .stp extension) created by your CMM vendor.

PC-DMIS requires these STP files to compensate for temperature.

Prior to compensating for temperature, ensure that these STP files reside in the appropriate locations on your hard drive:

- The DEA Structural Thermal Compensation method expects to find the Serv1.stp file in the C:\Thermal_OCX directory.

- The DEA Linear Thermal Compensation method expects to find the Serv1.stp file in the C:\Program Files\Thermal_OCX directory.
