I was curious if Pro/E had the ability to visually compare different revisions of a part or an assembly, to see what has been added or removed and what has stayed the same. See the example at the link here, for what I am referring to.
Nothing that slick built into Proe/Creo. You can overly the two parts, making sure they are different colors and look for differences. If you alternately make one transparent that can help.
Of course, you can export them both as STLs and then use that STL compare tool that you linked to.
In Part Mode
Analysis > Compare Part 'By feature' usually if you are comparing two versions of the same part and 'By Geometry' to compare any two parts.
The By feature option will tell you which features are different in the base model and the comparative model (do/do not exist, changed values etc.)
By Geometry allows you to set a measurement spacing and a tolerance and it will highlight the physical differences between two parts
