To create a Probed Single Point item

Use the Probed Single Point item to take a guided point on a model or a part. You can specify the nominal values for the single point by:

Note: Single Point On-the-Fly items are available only when creating inspections for CNC and Manual machines.

To create a Probed Single Point item:

  1. Open a Geometric group in the Sequence Tree.
  2. Click Home tab > Create panel > Geometry > Probed Single Point.

The Probed Single Point dialog contains the following areas:

Name — Enter a name for the item. The name is used in the inspection sequence, in the Report and Info tabs, and when referencing the item in other items.

Use nominals — Select this check box to enter or change the item nominals, and to compare the item measurements to their nominal values. Deselect this check box to disable comparisons with the item nominals.

When this check box is selected, an in-tolerance or out-of-tolerance indicator is displayed on the measured item's icon in the inspection sequence; the border of the item label is coloured to indicate whether the measurements are within tolerance; and the tolerance, nominal, deviation, and error values of the item are shown in the report.

When this check box is deselected, the Nominal boxes are disabled, no tolerance indicators are displayed and no tolerance, nominal, deviation, and error values are shown in the report for this item.

Note: To load the nominals from the CAD model, click and select From CAD Entity. To replace the nominals with the item's measurements in the current Measure, click the button and select From Active Measure.

Visible — Select this check box to display the item in the CAD view.

Output in report — Select this check box to include the item in the report.

Coordinate system — Select the alignment relative to which the item's measurements are to be reported.

To specify the alignment during the inspection, select <Active Alignment>. You can then select the alignment from the Active alignment list, or by adding an Active Alignment item to the inspection sequence.

Probe radius compensation method — Choose an entry in the Method list to specify how you want to compensate for the probe radius. Select:

Target point — Enter the nominal and tolerances for the position of the point.

Distance to target point — Enter the nominal distance between the target point and the projected point ::

Nominal surface

Actual surface

Nominal single point, which is the target point

Point taken at the centre of the probe

Point projected to the actual surface along the specified vector

Distance to target point

Distance to target plane

Distance on plane

Distance to target plane — Enter the nominal distance between the target point and the surface . This distance can be positive or negative, depending on whether the probed point is above or below the nominal point. In the example, the distance is negative because the probed point is within the material condition.

Distance on plane — Enter the nominal distance between the target point and the projected vector.

Point sources — Select this tab to use probed points from other items to measure this item.

For example, you can use the tab to create a measured cylinder by combining measurements from probed circles at the top and bottom of the feature.

To specify the sources for the probed points, select one or more items in the Available sources list, and then click to add them to the Selected sources list.

To remove sources, select the items in the Selected sources list, and then click .

Note: You can view the probed points used to measure the item using the Geometric Item Points dialog or the Info tab.

Click OK to close the dialog and save your changes.
