Filter Points to Selected Surfaces
This command offers a means to create a new set of points or point clouds (if point clouds are selected) based on the proximity of the points to a selection of surfaces.
There are 3 menu commands for this control:
-
Filter Points to Selected Surfaces - offers selection of list of surfaces for the filtering process
-
Filter Points to Selected Faces - offers a more precise selection from CAD surfaces, only including the selected surface faces.
-
Filter Points to All Faces - offers a more generic option that does not prompt for surface selection but uses all surfaces in the job file automatically.
A selection of useful controls are available which include:
Face Offsets:
-
Surface Offset. The necessary proximity to the surface
-
Edge Offset. The required distance from a surface edge, which allows removal of points too close to an edge.
-
Surface Offset Direction. Which can be set to both above and below the surface or in only a single direction.
Additional True Position Point Detection:
-
Include points within cylinder axis proximity. This option works independently to identify points at the center of holes. This can be quite helpful in associating points to GR-Circles or GD&T checks.
Output Limits
-
The Enforce Max Pts per Face in Output check box. This control ensures that no more than the specified number of points are included per face.
Output Grouping controlling both point and cloud output.
-
Create separate groupings for each face. provides a means to separate the output points into groups per face. Alternatively select the Combine into a Single Group for all Faces option.
-
Output Cloud Base Name This name is used when filtering cloud points to a surface.
-
Use Face IDs for Suffix check box. This option provides the ability to add an additional suffix with the face IDs. When disabled it will use a simple sequential index.
Cloud Thinning Options
-
Cloud Thinning Options. A list of cloud thinning controls are also available including randomized thinning, Nth point thinning, and min/max limits
When combined with the user of cloud based geometry relationships this command makes it very easy to extract features from a cloud using the available CAD to filter the cloud.
