#### Edit Probe Components

Double-clicking on a component in the Probe description area (in the Probe Utilities dialog box) opens the Edit Probe Component dialog box. The options that appear in this dialog box depend on the component you selected. The following two options apply to all components:

Edit Probe Component dialog box

This dialog box allows you to remove specific portions of the probe graphics from display and define a rotation angle about the connection.

In cases where the part geometry is particularly dense, you can temporarily remove some of the graphics to provide a better view of the features. To remove probe graphics:

1. Double-click on the specific feature description (in the Probe description area) that needs to be removed from view. PC-DMIS will display the Edit Probe Component dialog box.

2. Clear the Draw this component check box.

3. Click the OK button. The Edit Probe Component dialog box closes. Notice that PC-DMIS redraws the probe graphics without the indicated component and all other components above it in the Probe Utilities dialog box.

The rotation angle is primarily used to manually define the angle of knuckle attachments. To define the rotation angle about the connection, type the desired angle in the Default rotation angle about connection box (any angle from +180° to -180°). 0 is the default angle.

Additional Option for Star Probe Components

For star probes, an additional option is included when you double-click on the extension component in the Probe description area.

Edit Probe Component dialog box – Star Probe

Draw active tip only check box:

- If you select this check box, PC-DMIS will hide any non-active probe tips instead of merely highlighting the active probe tip in the Graphics Display window.

- If you clear this check box, PC-DMIS highlights the active probe tip as usual.

Additional Options for Disk Stylus Components

For calibration of a disk stylus when used with an analog probe, two additional options are included.

Edit Probe Component dialog box – Disk Stylus

Measure plane on bottom of disk check box:

- If you select this check box, four hits will be taken on the bottom of the disk to calculate a plane and therefore determine a measured vector associated with the plane of the disk.

- If you clear this check box, PC-DMIS will not take any plane hits, which means that there will be no measured vector. The vector for the plane of the disk will be the theoretical value from the model of the probe.

For a new probe, the default value is determined by registry setting ProbeQualAnalogDiskUsePlaneOnBottom, found in the Probe Cal section of the PC-DMIS Settings Editor. If this registry setting is set to 1, PC-DMIS will measure the plane. If this registry setting is set to 0, PC-DMIS will not measure the plane.

Distance from edge for plane hits box: If you are measuring the plane, the hits will be distributed in a circular pattern this distance back from the outer edge of the disk. The radius for the pattern of the plane hits will be the disk radius minus this distance.

For a new probe, the default value is determined by registry setting ProbeQualAnalogDiskBottomHitsDistanceFromEdge, found in the Probe Cal section of the PC-DMIS Settings Editor. The units for this registry setting are always in millimeters. However, the value that you enter in the Distance from edge for plane hits box will be the units of the part program that you are using (that is, either inches or millimeters).

Note: In 2012 MR1 and higher, the ProbeQualAnalogDiskBottomHitsDistanceFromEdge and ProbeQualAnalogDiskUsePlaneOnBottom registry settings provide the initial defaults for new probes. You can then define specific settings for individual probes in the Edit Probe Component dialog box.
