### Differences between PC-DMIS NC and PC-DMIS

The following differences exist between the PC-DMIS NC program and PC-DMIS:

- PC-DMIS NC does not run interactively with the NC machine. However, PC-DMIS NCI does work interactively (See "PC-DMIS NCI Differences"). PC-DMIS NC creates a stand-alone NC program file which is executed on the NC controller. Embedded in the NC program file is all the information PC-DMIS CNC Server needs to select the associated PC-DMIS program. The PC-DMIS CNC Server program then loads probing data from the NC machine into PC-DMIS NC and executes the selected program.

- PC-DMIS NC version 1.0 typically cannot send data to the NC controller during execution. Controllers shown with NC or NCi in the "PC-DMIS NC: Introduction" topic are capable of updating work offsets, tool offset, and variables in the control. Controllers for which this is not possible are shown with (NC- not interactive).

- Probing paths are static and cannot be changed for all NC versions. These paths are generated from the part model's nominal geometry prior to execution. Interactive functions that modify the path during program execution have been disabled in the PC-DMIS NC menus. Since you create the part program in offline mode the path cannot change. For example, you will be unable to modify a path based on a previously measured alignment. PC-DMIS NCi versions operate interactively with PC-DMIS sending each path point to the control allowing logic operations to control program path execution and iterative alignments.

- Alignments computed from features will only be used during the analysis phase for NC.

The following PC-DMIS topics list particular items as either supported or unsupported in PC-DMIS NC. Where PC-DMIS NCI supports or does not support a particular feature, notation is provided. Otherwise, both NC and NCI are both either supported or unsupported. For information on these specific items, view the main PC-DMIS reference manual:
