#### Hit Targets Controls

The controls shown in the Hit Targets tab in the Probe Toolbox let you edit, test, and modify the targets and parameters used to measure the feature.

At the top of the tab is this toolbar:

At the bottom of the tab are some additional items:

The following table describes what these controls do:

Define Target Button | Description
| The Target Type list lets you choose the target type when creating new targets. The available target types include:

- Optical Comparator Hit Target

- Gage Hit Target

- Manual Hit Target

- Automatic Hit Target

| The Parameter Set list lets you change between these parameter sets:

- Edge

- Filter

- Focus

- RGB Mixing

These are discussed in "Available Parameter Sets".

| The Target Feature Coverage list allows you to quickly create target sections in order to only measure a subset of a feature. Limiting coverage can decrease feature execution time. For example, a large feature measured at high magnification may require lots of camera positions to get all the edge points. Selecting 10% coverage would only measure edge points at certain locations around the feature amounting to 10% of its form.

Notice in the example below that the same feature covered at 100 percent is altered to have many targets that provide a coverage of 50 percent.

Profile 2D - 100% Coverage | Profile 2D - 50% Coverage

| The Set Target Feature Coverage Active Targets list determines the number of targets to use to display the selected coverage percentage in the Target Feature Coverage list. The default value is four. For example, a 50% coverage on an arc, with a value of 7 active targets set from this list, would result in target sections that looked like this:

Example Active Targets

| The Hit Target Color listspecifies that color that will be applied to the feature hit targets. This allows you to differentiate between features, or to ensure visibility on different types of surface.
| The Nominal Color list specifies that color that will be applied to the feature nominal line. This allows you to differentiate between features, or to ensure visibility on different types of surface.
| The Lock Hit Targets to Part button secures the size, position or rotation of the target.
| The Center Hit Target button centers the target or FOV. What actually moves depends on the status of the Lock Hit Targets to Part button. If first select the Lock Hit Targets to Part button, and then select the Center Hit Targets button, PC-DMIS Vision moves the current FOV to the target. This is only available on DCC Motion machines.

If you deselect the Lock Hit Targets to Part button, and select the Center Hit Targets button, the target moves to the current FOV.

| The Insert New Hit Targets button inserts a new target area. You can then set up different parameters for this specific area of the feature.
| The Delete Hit Targets button will let you delete a previously inserted target from the feature.
| The Reset Hit Target(s) button deletes all of the previously inserted target areas from the feature, leaving the single default target.
| The Test Hit Targets button tests the automatic Target Edge detection for the currently selected target(s). PC-DMIS Vision displays any detected points in the Live View tab of the Graphics Display window.
