User-Defined Measures
To define measures that are a function of time, frequency, local measures, or measures relative to a coordinate system other than the WCS, you need to create a user-defined measure. You cannot use the name of a predefined measure for a new measure, or create a new measure that is identical to a predefined measure, unless you associate the measure with a UCS.
Measures you define may apply to the entire model, to an entity or entities you select (the type and number of entities you can select depend on how you define the measure), or to an area near a point.
Keep in mind the following, when you begin working with the user-defined measures:
If you plan to make a measure relative to a coordinate system other than the WCS, you need to have that coordinate system in place.
If you plan to place a measure at a specific point on an exterior surface, your part needs to include a datum point at that location unless the location is a vertex.
If you plan to place a point measure on a shell model surface that Creo Simulate may compress during analysis, see Model Entities and Idealizations to learn about how Creo Simulate processes loads placed on compressed surfaces.
