Results Display Changes: The developers have made a lot of changes to the results display: Updated the Analysis window result page to display the results in a Table view, moved GeoFactor to the results page as its own results called GeoFactor Analysis and added GeoFactor to the Contributor Analysis results.

•Monte Carlo Analysis: Added new statistic: Recommended GD&T Value. It is the value that should be used when comparing the 3DCS model output to GD&T drawings.

•GeoFactor Analysis: Moved to the same dialog as the Monte Carlo Analysis. GeoFactor Analysis shows the results based on the tolerance range limits instead of a Gradient Step.

•Contributor Analysis: Previously called Sensitivity Analysis, we changed Contributor Analysis to use the GeoFactor algorithm. Each tolerance will now be set to their Median, rather their nominal.

GD&T Measure creation: Create measures based on Assembly GD&T. Users will be able to extract Assembly GD&T, defined in the CAD system, as GD&T Measures in 3DCS. These new type of measures will check the features, holes or pins deviation, defined by their datums.

GD&T Checker and Relationship Wizard: is a tree and validation dialog for validating Features and Points that are used in/with other MTMs, Features and Points. The GD&T Checker checks each generated or 3DCS defined GD&T for Syntax, DRF, zone type and surface type.

Feature Groups: Organize sets of Features and MTM data into different groups. Groups will allow users to add organization to their 3DCS tree, move important or non-important 3DCS features and reduce large model tree structure.

Visualize Effect: is a tool that allows users to graphically see the impact of a single tolerance or float in the model.
