use a mystery part. the footprints are just what you need. do we want some other parts that have wires in the breadboard view? or something like a breakout board?

I guess the students felt that it would be clearer what they meant if there were actual connector-type parts that went onto the pcb. right now they are using LEDs as pseudo-connector parts because they have the right footprint, but I'm not sure that using a mystery part in this case makes the intent any clearer

We definitely need "connector" parts, they are on the list for some time now. We need them as distinct parts because that's the way people are thinking about them.
Connector parts are however tricky: E.g., a motor that is connected to a screw terminal doesn't need its own footprint on the board. So we need some kind of a special solution for this. Some alternatives:
What do you think?

I think some combination of the two solutions Andre cites would be good. I think connector parts should be available in both breadboard and pcb view because some people use connectors in their breadboard setups. But i do like the idea of fritzing doing some of the work in PCB view if i decide i want a connector here, but didn't put one in my breadboard.

This is exactly the problem that the mystery parts are supposed to address. You don't have the part in fritzing but you know that you are just going to wire up your "wiz-o-matic 3000" with 3 wires that you solder onto your board. Just take a 3 pin mystery part and it will give you a footprint for a 3 pin header. Change the label to say "Wizomatic" or whatever.
Jenny suggested that maybe the breadboard design for the mystery parts could change so that this is conceptually clearer. I vote for pink blocky shapes with the question mark on them.
Real connectors, terminals and headers are a separate issue that we have to address by making new parts.

Yes, we definitely need "connector" parts. And my choice would never be to make them pink blocky shapes ;-)
The biggest concern with connector parts is that the user doesn't understand what they are for, how they exactly work, and specifically: what is soldered to the board, and how this connects to what. Therefore, I think the connectors should be visible parts in every view. In fact the connectors should be looking very real, like all the other breadboard parts we have. Only by making it obvious how they connect do we convey how the part would work as connector.
The issue is that most of the times, a connector doesn't come single. It often has some other connector attached to it. Sometimes that connector is just a cable end, often it is the opposite gender connector type. So connectors in the part library might have to be default available as modules: a screw connector and a cable, or a female socket and its male connector part.
The real issue then is how to tell that one part of the connection should not be exported for etching etc. But this issue is the same issue we have with modules in general: how to tell that you don't need the arduino etched and not the ethernet shield, but only the inbetween, ... or the arduino and the inbetween, but not the ethernet shield ... or ... etc. So it becomes a matter of selecting parts for production (or selecting parts to be excluded from production ... though I would like to see these connecting parts on my BOM, so I remember to order them)
Furthermore, I would like to see additional wires to go with these new connectors, a double red-black power wire, attached to a 2 pole female power connector; a small coaxial cable like the ones going in your headphones; and a flat ribbon cable to be inserted in the female header connector socket thingie (or whatever they wanna name these)

We now have basic connector parts, but some of the above side issues still need to be figured out.

that's my first comment here, so i hope not to say stupid stuff. i have couple suggestions that working toghether may solve the problem: -allow user to hide object in different views (like, "i don't want to se connectors in my breadboard view, neither arduino in pcb view") -add an object in pcb (hidden in other views) like generic hole(i'm using female connectors for this now) -add external wire in pcb view to route all the nets also with out of the pcb objects. eg: motor transistor arduino on the pcb i want screw connectors for the motor, i put the motor outside the pcb and link it to the screw headers with external wire. i want to connect the pcb with 3 pins in arduino troucht wires, i make three holes in pcb and connect with external wires . then i hide screw connectors and holes in other views(no usless header in breadboard) and hide arduino and motor in pcb.
Now, that seems to me a way to fix this.. but since i'm not really sure on how fritzing works, i'm not sure this can be simply implemented.
let me what you think. Giovanni

for parts that will themselves be off the pcb, but will be connected to the pcb with wires
