Authoring manufacturing process plans > Managing product and manufacturing information (PMI)
Edit PMI object information
You can add additional information to a PMI object to define attributes that pertain specifically to your process. This information, which does not exist in the CAD model, is saved only in the context of your process.
Procedure
In the PMI Manager view, select View Menu→Columns.
In the Available Columns box, type
PMI, and then add the columns for which you want to add information.Click Apply, and then click Close.
Review or add PMI information.
Note You can edit the following columns.
Property
Description
Key Characteristic
Supports aerospace and defense enterprises that must adhere to the SAE AS9103 standard. You can identify features that must be controlled during production and that when changed, require a first article inspection. You can select the values DKC (Design Key Characteristic) or PKC (Process Key Characteristic).
Occurrence Effectivity
Lets you hide or show assembly parts and PMI objects associated with those parts based upon occurrence effectivity settings.
PMI Criticality
Allows you to select values such as Critical, Major, Minor, or Documentation Only to indicate each PMI object's degree of importance when you are defining inspection operations.
PMI Description
Specifies a description that can be presented in the work instructions.
PMI Dimension Type
Specifies the type of the dimension, such as radius or diameter.
PMI Frequency
Specifies information for the MES system representing the frequency of the inspection, for example, whether it applies to every instance, once in a lot, first and last, and so on. The precise semantics of this property are project-specific.
PMI GD&T Code
Specifies XML code representing geometric dimension and tolerancing information.
PMI Marked As Deleted
Indicates whether the PMI object is deleted in NX.
PMI Not For Inspection
Prevents the PMI object from being included in the accountability check and also from being exported to MES.
