Previous: Surface evaluation tool overview

EvalViewer now provides a set of menu options to allow you to compute comparison information for cloud, lines, curves, polygons, and surfaces. The tools are intended for two main applications:

• Verifying that a surface design meets any dimensional criteria defined in the raw data used to build the surfaces in reverse engineering applications.
• Validating inspection data acquired from a part that was created from a given surface model in computer aided validation applications.

The comparison functions in the Compare menu allow comparisons of the following types:

• Clouds to Clouds
• Clouds to Lines
• Clouds to Polygons
• Clouds to Surfaces
• Lines to Lines
• Lines to Curves
• Lines to Polygons
• Lines to Surfaces
• Polygons to Polygons
• Polygons to Surfaces.

All options create deviation vector information as output. In addition, the Clouds to Polygons and Clouds to Surfaces create color error maps that provide informative visuals showing the dimensional trends in cloud data that are hard to assess otherwise.

Please refer to the sections in the remainder of this document. You will find a section on Using EvalViewer as a Comparison Tool as well as an EvalViewer Reference section describing all Menu Picks and Tab Buttons.
