#### Advanced Measurement Options Area

Nominal Mode

FIND NOMS: PC-DMIS Vision will pierce the CAD model to find the closest location on a CAD edge (or surface) to the measured point, and set the nominals to that location on the CAD element.

MASTER: If a feature is created when the Mode list is set to MASTER, then the next time the part is measured, PC-DMIS Vision will set the nominal data equal to the measured data. The Mode list will then be reset to NOMINALS.

NOMINALS: This option requires you to have nominal data before the measurement process begins. PC-DMIS will compare the measured feature with the theoretical data in the dialog box, using the measured feature for any necessary calculations.

Best Fit Math Type

A Vision Auto Feature Circle also allows you to define the Best Fit Math Type. This is discussed in the "Best Fit Type" topic of the PC-DMIS Core documentation.

Relative to

This allows you to keep the relative position and orientation between a given feature (or features) and the auto feature. Click the button to open the Relative Feature dialog box to select the feature or features to which the auto feature is relative. Multiple features can be defined for each axis (XYZ) relative to your auto feature.

Analysis area

The Analysis area allows you to determine how each measured hit/point is displayed.

Pt. Size: Determines how big the measured points will be drawn in the Cad View. This value specifies the diameter, as is specified in current units (mm or inch).

Graphic Analysis button : When switched on, PC-DMIS will do a tolerance check on each point (how far from theoretical position it is), and draw them in the appropriate color, based on the current defined dimension color range.

+ Tol: This provides the positive tolerance from the nominal, and is specified in current part program units. Points that are greater than this value from the nominal will be colored based on the standard PC-DMIS plus tolerance color. See the "Editing Dimension Colors" topic in the PC-DMIS Core documentation.

- Tol: This provides the negative tolerance from the nominal, and is specified in current part program units. Points that are less than this value from the nominal will be colored based on the standard PC-DMIS negative tolerance color. See the "Editing Dimension Colors" topic in the PC-DMIS Core documentation.
