View Controls
A saved view can be recorded with each feature check and displayed when it is either activated for measurement or evaluated for reporting purposes. Saving a preset view with a check ensures that a comfort- able viewing angle is obtained whenever measurement is in progress. The GD&T Inspection >Design, Inspection>Inspect workflow process provides a convenient way to predefine views for a series of checks. The views from the Inspection Design interface are saved automatically and can be recalled or edited by going directly to this section in the specific datum or feature check.
-
Set. Defines the current view perspective and zoom depth and saves it with the check.
-
Clear. Removes the currently saved View.
-
Switch To. Resets the graphics to the saved view.
In addition to the saved view orientations an option has been built into the right-click menu of the feature check category to enable Show Only Active Feature Check. When enabled, this option changes the visibility of the annotations such that only the annotations directly linked to the selected check are displayed. This included the selected check, the datums it references and any addition annotations that share the same feature associations.
Datum Alignment
A GD&T alignment performs a direct fit to the datums as an initial alignment, the measurements of the features to be checked are then divided up and the final evaluation process is conducted. These options provide tools to troubleshoot each aspect of the evaluation process.
-
Enable Datum Alignment. Un-check for manual alignment. This performs a GD&T evaluation of the check in the current job alignment without using the GD&T control frame datums to align. When disabled this is no long a standard GD&T evalu- ation and the datums with be marked out in the report. How- ever this option can be helpful in troubleshooting your results.
-
Disable Initial Datum Alignment. This option provides the ability to skip the normal datum alignment process prior to point and feature processing. When pre-aligned this option can help ensure that the correct points are associated with the correct features in a pattern. However, it requires the points to be closely aligned to the part in order to evaluate correctly.
-
Enable Custom initial Alignment. When a custom initial align- ment is specified in the annotation properties this check box allows it to be applied as the first step in the evaluation pro- cess, providing the GD&T evaluate a better initial alignment.
Cloud Thinning
Controls the extent of thinning performed on point clouds associated with this check during evaluation.
-
Use Global Defaults. With this default option enabled, the check will use the system thinning controls defined in the Fea- ture Check Cloud Thinning settings on the Analysis tab of the Users Options.
-
Settings. This button opens a dialog allowing you to specifically define the thinning used in that check, independent of the global settings.
Datum Alignment
-
Enable Datum Alignment. When unchecked, the feature check will be evaluated in its current position and the datum alignment will not be performed. This is primarily for diagnostic purposes only (see “Disabling Datum Alignment” on page .
