### Option 4

In the Auto Features dialog box, each tab entry has a check box for Auto PH9 . When this option is checked, PC-DMIS will take the definition of the feature to determine the best tip shank vector to measure the current feature. It will then use this tip shank vector to calculate the best A,B combinations. These will be displayed in the Wrist Angles Matching Requested Vector dialog box described in "Option 3" above.
