Filtering Clouds to Vectors by Resolving Points
Given a set of clouds and a set of vectors, SA can filter the clouds to the vectors. You provide a desired threshold around each vector, a proximity to the vector’s base, and the minimum number of required points, and SA will—for each vector—extract the points that meet the specified thresholds and average them into a single point.
This command is useful, for instance, when you have a set of nominal vectors on a design surface that indicates where you’d like to measure, and you have a surface scan of the part. The command will filter the clouds to those vectors.
To Filter Clouds to Vectors:
-
Pick the clouds you’d like to filter.
-
Select the vector groups you’d like to filter to.
-
The Filter Clouds to Vectors dialog will be displayed:
-
-
Output Group Name. The name for the resulting point group.
-
Minimum Proximity. The minimum allowable distance from a point to the vector to be considered.
-
Maximum Proximity. The maximum allowable distance from a point to the vector to be considered.
-
Max Distance from Vector Begin. The maximum distance that a cloud point can be from the base of the vector to be considered.
-
Minimum Number of Required Points. The minimum number of points required for an averaged point to be created. If this minimum is not met, no averaged point is created.
