Cloud Point Proximity Filter

Each GR-Feature has its own auto-filter proximity settings built in. These initial settings are pulled from the User Options>Display Tab, GR Proximity Filter and saved with the feature. They can be accessed at any time through the Right-click Configure Cloud Trapping Filter option. This will open a unique feature type specific set of controls.

 

In order to maintain data integrity the source cloud is saved with a GR-Feature but not edited by it. Instead, a sub-sample of the source cloud is made as a copy and linked as well so that it can be used for the purpose of fitting and outlier rejection. This allows you to more unwanted outlier cloud points with edition the source cloud:

 

Feature Specific Filtering (Circles and Slot)

The 2023 version of SA added additional extraction methods for circles and slots to simplify hole extraction. These methods are based upon a standard developed for Volkswagen (VW) to facilitate automotive applications.

These extractions are available through the use of the right-click Configure Cloud Trapping Filter option. The reference or input cloud is saved and extractions are performed from this reference. This extraction process will build additional clouds within the GR Circle as show here:

Extraction methods include:

Basic Filtering:

 

Advanced Filtering:

These two methods fill almost all the extraction solutions needed for most parts.

 

Additional Advanced Filtering Options:

 

Use the Apply to Selected and Set As Default options to apply settings between features and adjust the defaults for your application.

Additionally, all the relationships in a collection can e forced to be recomputed using the right-click category option Refresh Filtered Cloud Data.

 

The Auto Filter to Nominal Geometry >3D Geometry option can also be used to perform this filter process. It will link an input cloud to the geometry and apply an extraction. An option to “Use Filter Settings” is available to directly take advantage of the saved settings from with each feature or the Settings button will open options for filtering and sub-sampling.
