Clearance and Creepage Extension (CCX), available on the Analysis tab, performs an automatic clearance and creepage analysis. However, you must specify various parameters for CCX to perform this analysis.

Before you start CCX, you can hide certain components of the assembly model so that these components are excluded from the analysis. CCX then loads only the visible components of the assembly for analysis. After you start CCX and begin the analysis, hiding and unhiding components do not affect the analysis.

In addition to the Help topics for Clearance and Creepage Extension, a tutorial is also available. You can find this and other tutorials in the Creo Parametric Help in the table of contents under Creo Tutorials. You also click under Related Links in this topic.
