Graphic Validation.
Now that you have completed your model, you can watch the build by build variation of the model.
•Click 
Nominal Build.
•Click 
Deviate and examine the Shifter Variation.
In the assembled position, you can see the part variation changing the positions of the Parts from build to build.
•Click [Close] in the Deviate dialog.
Validate Tool
The 
Validation function checks for errors in the Moves, Measures, and Tolerances in the assembly tree. The Validation function can be used before and after running the analysis.
Procedure for performing Pre-Analysis Validation:
1.From the 3DCS Tools toolbar, select Validate Model.
2.Validate information will be displayed on screen.
3.Double click on any issues listed under Summary window, you want to fix.
DOF Counter
Select DOF Counter 
from the Mechanical Add-Ons Toolbar. This displays all the Mechanical moves of this model and their available Degrees of Freedom. Through this feature the user can understand,
•Number of Degrees of Freedom restrained or dropped on each part
•The Nominal Build position after each move
This tool helps in testing each move while checking the Degree's of Freedom can give more insight to how to better build a Mechanical model.
•The top most row in the dialog lists all the parts in the Model
•The numbers right below that will display the total degrees of freedom left for each Part.
•The Left most column will display all the moves in the Model
•The corresponding rows of each move will display the DOF number. This shows how each move affects the Part's DOF number.
Relationship Tree
The 
GD&T Checker and Relationship Wizard (Relationship) is a tree dialog that shows relationships of features used in Moves, Tolerances/GD&T and Measures (MTMs). This dialog also shows GD&T errors and warnings, or if features are used or not used in GD&T/3DCS Tolerance but are used in other MTMs. The GD&T Checker/Relationship Wizard can be found under the Validation menu.
This will help the user to find out Features that are used in the Moves/ Measures but were not Toleranced, also to find any errors in GD&T creation.
Visualize Effect
Visualize Effect is a tool that allows users to graphically see the impact of a single tolerance or float in the model.
One input at a time is deviated to high, median, and low sequentially in the model. When the model is in its built position this represents a graphical visualization of how individual tolerances or floats translate through the model. It is meant as a tool for the user to better understand the contribution of a specific tolerance or float that they may be surprised to see (or not see) in the results provided by the 3DCS Contributor Analysis.
For Example,
•Open the Position GD&T on the Frame
• Click Visualize Effect button under show.
The Dialog will list all the features Toleranced in the GD&T, from which the user can select one and see the effect of that tolerance on that particular feature.
This option is also available in the Analysis summary page to check effect of each contributor .
