This tutorial shows a way how to split a face of a solid to apply different colours over it, up to my information there is no specialized tool for such operation in Creo Parametric.
The video does not have audio assistance but I have given sufficient amount of pause over the tool and their tip so that they can be read easily. In addition this annotations are also applied over important places… so please focus on them to understand what is being done and how……..
