About Configuring Creo ModelCHECK and PTC Windchill for Shape Indexing
You must configure Creo ModelCHECK and Windchill for Creo ModelCHECK to index shapes in a Windchill database.
The shape information is stored in the following mass property parameters that are available in the model since its creation. To generate these parameters when you run Creo ModelCHECK, the option MC_SI_PRINCIPAL_MI must be set to its default value Y in the config_init.mc file.
MC_VOLUME—Specifies the volume for shape indexing.
MC_AREA—Specifies the surface area for shape indexing.
MC_INERTIA_1—Specifies IXX principal moment of inertia for shape indexing.
MC_INERTIA_2—Specifies the IYY principal moment of inertia for shape indexing.
MC_INERTIA_3— Specifies theIZZ principal moment of inertia for shape indexing.
Additionally, you must configure Windchill to record these Creo ModelCHECK -designated parameters. That is, for each of these Real Number mass property parameters you must create an equivalent Windchill global attribute with the following properties:
Mass Property Parameter
Windchill Global Attributes for allowable tolerance
Data Type
Quantity of Measure
MC_VOLUME
MCSI1_TOL
real number with units
Volume
MC_AREA
MCSI2_TOL
real number with units
Area
MC_INERTIA_1
MCSI3_TOL
real number with units
Rotor Inertia—Moment of Inertia about the first principal axis.
MC_INERTIA_2
MCSI4_TOL
real number with units
Rotor Inertia—Moment of Inertia about the second principal axis.
MC_INERTIA_3
MCSI5_TOL
real number with units
Rotor Inertia—Moment of Inertia about the third principal axis.
New CAD document instances automatically incorporate these Creo ModelCHECK -driven global attributes. You can edit these attributes and assign them any value in Windchill. However, if you lock these attributes, they are read-only, are not available for editing in Windchill, and are driven from Creo ModelCHECK.
Creo ModelCHECK searches for duplicate models only when the database of CAD Documents is populated with shape indexing attributes. You must run Creo ModelCHECK before you check in the CAD documents to interactively populate the database with the shape information. Optionally, you can use Creo Distributed Batch and a Creo ModelCHECK task group to batch populate the database of CAD Documents with the shape indexing attributes.
