Auto Filter
If you have measured your part independently of any type of Guided Inspection or Measurement Trapping but you have pre-aligned to a CAD model, it is still quite simple to associate points to the necessary checks. To do so, use the auto filter function to assign points to the correct checks. The steps in this process are as follows:
-
Double check that datums feature checks are built from your annotations and ready to receive points. If not right-click on the annotation category and select Make Feature Checks.
-
Navigate to GD&T > Feature Inspection Auto Filter All Checks. Select individual points, point groups, or even point clouds, and choose a proximity threshold used to include points with particular checks. Then simply press OK.
-
If you need to pick up additional point measurement taken along the axis of a cylinders, these can be obtained with a second run using the additional true position point detection check box. Also if you want to populate only a selection of checks you can used the function GD&T > Feature Inspection Auto Filter Selected Checks. This function works the same only it will ask you to choose which checks to con- sider.
-
Once this is done then navigate to GD&T > Evaluate all Feature Checks
to complete the GD&T analysis.
This is a particularly useful approach to GD&T analysis when using a scanner. If you initially locate a scanner and then fully scan the part you are evaluating you can then filter the scan data to the CAD Faces associate the individual scans to the appropriate Features and in two clicks of a mouse button go from a single unfiltered cloud to a completed GD&T analysis ready for reporting.
