PTC Creo ModelCHECK Teacher: Parameter Information
A parameter is a value that can be attached to a Creo Parametric model which contains non geometric information on the model. For example, part numbers or the name of the designer can be stored in parameters.
Types of Parameters used by PTC Creo ModelCheck
• Parameters—Creo ModelCHECK verifies that the model contains a standard set of parameters. If they are not there, you can use the Update Parameters and Layers button from Netscape to add the missing parameters to your model. A second option is to use Set Up, Parameters, Create to add the missing parameters from within Creo Parametric.
For example, the following parameters have to be in all your parts:
◦ MODEL
For example, the following parameters have to be in all your assemblies:
◦ DRAWN_BY
◦ MATERIAL
◦ DESCRIPTION
◦ PDM parameters—Parameters can be designated specifically for use in PDM. This means that when the model is submitted into PDM, these parameters can be extracted as attributes and submitted into the database.
• To designate a parameter, use the following menu picks: Set Up, Parameters, Designate, Parameters, then pick the parameters to designate. The parameters must already exist in the model.
For example, the following PDM-designated parameters have to be in all your parts:
◦ PN
For example, the following PDM designated parameters have to be in all your assemblies:
◦ PN
• NULL parameters—NULL parameters are parameters that have been assigned to a model but have not been given a value. To add a value to a parameter, select Set Up, Parameters, Modify, and select the parameter.
For example, the following parameters have been designated as null in parts:
◦ EMPTY
◦ PN
For example, the following parameters have been designated as null in assemblies:
◦ DRAWN_BY
◦ MATERIAL
◦ DESCRIPTION
• Parameters used in drawings—Note and table information in a drawing can be driven by model parameters. An effective way to do this is to create a drawing format. This information is then available each time the format is used.
