Michael !
In general I´m with you with what you say .... but this time I´m not !!!!
Its not something that is worthwhile only for architectural porposes !
If you make a mechanical object and make a rivet a component you could easily place those on
a surface using this feature !
I see it as part of an updated array tool too !
I understand that its not No 1 priority but its not ONLy usefull for architecture !
It would be a "COOL" feature for the future even for mechanicals !

Hi Peter, yeah you're right and in fact I guess that mechanical solid modelers like SolidWorks and Pro/E often have a pretty similar kind of "feature library" type thing as well.

But again if you have the need to create such repeated fasteners quite a lot, then again I would suggest using one of those modelers that is focused very much on mechanical part design like SolidWorks, they will do a better job of that type thing in a similar sense to what I was describing for an architecture-oriented modeler being easier to use for architecture.

I'm sure that what you have in mind will work OK, I just wanted to share my small experience...!
