Revit Add-In
Actually, I think the most effective way to answer these in full and fully comprehend the answers would be to work through the getting started tutorials yourself. That would explain most of the questions:
Still, here are some quick first takes on them anyway:
> Do we have a web where are listed all the Revit add ins ? , like a catalog so we can find more info about them.
Well, there is the Autodesk Revit AppStore. However, you are perfectly free to implement your own add-in and NOT register it in the AppStore, so the AppStore is by no means a complete list. So, the answer is definitely NO if you insist on the term 'all'.
> All the Add-Ins are visual options inside Revit ?
No, you can implement a Revit add-in that presents no UI at all and just reacts fully automatically to certain events. Most add-ins do implement a UI, though.
> It's supposed all the add-Ins should be displayed in the Add-Ins ribbon tab ?
No. That is completely up to the add-in vendor.
> What are the first steps to create a new add-in for Revit ?
Work through the getting started material listed above.
> Is there any compliance / policy to bear in mind about the creation of an Add-In ?
No. Just do not corrupt your client's BIM.
> Does Dynamo Player is considered as an Add-in ?
I don't now. Who cares?
