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.
Enter the desired options, then click OK.
