Reset properties and counters face


I’m working in a module, and need to know if some things are possible:

  • Having different properties within a property sheet. Can I reset with a Global Button or something like that counter properties on it’s property sheet?

  • Having a piece prototype two layers (Front/Back), Can I have a global button/key to flip all this prototype pieces to a specific side (layer)? It should be Front…

  • Having some pieces invisible, Can I make them visible with a global key/button?

As you can see, all the questions are similar.

Thanks in advance,
