Total Runout GD&T is typically used to vary the location of a cylindrical Feature of Size such as a hole or pin, or vary the form of a planar surface relative to an axial DRF.
Creating Total Runout Procedure:
1.In the GD&Ts dialog, select Total Runout in the drop-down list and select [Add GD&T]. This will open up the GD&T dialog.
2.Underneath the Features list, select [Add].
3.Select the feature(s) whose location or form should be varied by this GD&T.
4.Click [OK][Close] in the Pick FeatureSelect dialog
At this point the GD&T dialog will pop back up. Notice that the features selected are now in the Features list in the top half of the dialog.
5.Enter the range in the text entry field.
6.Select a DRF, or From Nominal from the Datum Reference Frame drop-down. See Datum Reference Frames for more information about creating and using DRFs.
7.Select [OK] to exit the dialog and the save the GD&T.
How this GD&T Varies the Feature - Diametrical Feature:
In accordance with ASME or ISO standards, unlike with other GD&Ts within 3DCS the type of deviation for a Total Runout GD&T is determined by the feature(s) selected and not be inputting a specific zone shape. For a diametrical feature in the Features list, the Total Runout GD&T varies the location of the diametrical feature.
A sample diametrical feature with how a Total Runout GD&T would commonly deviate it is shown below.
Note: While only a few deviated locations are shown below, the actual variations will use the entire specified zone.

Note: The default distribution setting for a Total Runout GD&T with a diametrical feature is Right Skew. Because of how 3DCS internally handles 2D distributions, a Right Skew distribution will yield a Normal distribution if measured in any direction perpendicular to the axis of the varying feature. It is not recommended that the distribution is changed from Right Skew.
How this GD&T Varies the Feature - Planar Feature:
A Total Runout GD&T when applied to a planar feature will instead deviate the form of the feature. When deviating form, each node on the feature will deviate independently of all other nodes on the surface.
A sample planar feature with how a Total Runout GD&T would commonly deviate it is shown below.

A Total Runout GD&T will only work with axial or planar features.
