### Setting Start Points for Multiple Arms

PC-DMIS allows you to assign start points for the current arm by selecting the Set Start Point icon from the Edit window toolbar or by right-clicking in the Edit window in Command mode and selecting it from the shortcut menu.

To set multiple start points, change the current learn arm before clicking on the Set Start Point toolbar icon.

| A special start point arrow will appear in the left margin of the Edit window in a color that corresponds to the active arm color on the Active Arms toolbar. The screen capture to the left shows that Arm 1, in red, will begin execution at CIR3 while Arm 2, in green, will begin execution at CIR2.

If you cancel execution, PC-DMIS will automatically move the start points for each arm to the command where execution was cancelled for each arm.

Start points tell PC-DMIS to begin the program's execution at that point when you select the File | Partial Execution | Execute From Start Points menu option. For information on using Start Points, see the "Setting Start Points" topic in the "Editing a Part Program" section.

Important: Be aware that if the current tip for that location in the program does not match the current orientation of the probe head, PC-DMIS will not try and go back to execute the tip command above it in order to change the tip orientation.
