Any Android free app regarding cad works somewhat similarly like pro e ?
You've really limited your options.
Free CAD programs are pretty awful, and an Android based app further limits the pool.
Does Google Sketchup work on a tablet/phone? It may be an option. I don't think you'll find anything similar to ProE on Android in the near future. Maybe a CAD viewer, but not a CAD program that will create complex/detailed models.
Give us an idea of what sort of models you hope/plan to build with a free Android app, and maybe someone will have a better suggestion.
