Vector Construction Options

 

Vector Group from Existing Vectors

Creates a new vector group from selection of individual vectors.

 

Vector Group From Existing Vector Groups

Creates a new vector group from selection of existing vector groups, building a composite vector group.

 

Scale Selected Vector Groups

Creates a new vector group scaled about the selected frame. User may select a scale factor for each component of the vectors using the following control:

 

Copy Vector Groups Excluding Obscured Vectors

Creates new vector group only coping visible vectors. Vectors blocked from current point of view are not copied.

 

Area Profile Check

Area Profile check builds a new vector group to display the relative difference between the evaluated vector group(s) and the reference vectors with a specified area.

The Area Profile check has several inputs:

Reference Vectors. This can be a grid of vectors across the model which designate the centroid of an evaluation region. These reference vectors are used to define each evaluation region and they also define the base magnitude for comparison within each region.

Reference Vectors can be simply sub-sampled or built yourself. The spacing of these reference vectors define the evaluation coverage. With more gaps, regions will be missed, however, with more overlap you end up with redundant data and a slower evaluation:

As an example, if you wish to evaluate the area profile at 0.005” in every 5” segment using the following Reference Vectors

This Area Profile Check would produce the following result:

The evaluation process is as follows:

  1. For each reference vector a list of vectors is created that fall within the evaluation radius.

  2. For each vector in the list a new vector is created with the same position and orientation. The magnitude of this new vector is equal to vector magnitude minus the reference vector magnitude.

  3. The color (Red/blue out of tolerance, or Green in tolerance) is set based upon your specified tolerance.

The resulting vector group shows the difference between the reference vector magnitude and the returned vector for each evaluated region and can be useful in evaluating the relative change in magnitude within a region.
