Filter Data to Nominal 3D Geometry

The 3D Auto Filter option can be used to perform feature extraction based upon proximity using geometry relationships with a nominal feature defined. Selecting this option will bring up the following dialog:

 

Using the Nominal Geometry Auto Filter dialog.

  1. It provides a means to select a list relationships you would like to detect and a list of point clouds to filter from. It then will search through each relationship and all the clouds and populate all of them with the results at one time.

  2. It can be used “Live” as part of the Nominal Geometry Relationship build process. With the dialog open and the Live Auto Detect check boxes checked. Any newly built compare to nominal geometry relationship will be automatically analyzed and features extracted as part of the build process.

 

  1. Alternatively the same filter controls can be accessed for points well as clouds. See more on points Points Here.

 

The Nominal Geometry Auto Filter dialog offers the following options:

Relationship and Point Clouds Selection.

 

Cloud Thinning Controls

 

Settings. The settings button provides direct access to a set of generic filter controls that can be used if feature specific settings were not set in advance.

Use Filter Settings. With this option enabled the specific settings for cloud filtering set in each included feature will be used for the filter process.

 

Auto Filter. The auto Filter button triggers the extraction process.
