Is it possible to make an interactive symbol?

[GRNDPNDR]

I'm trying to make a relay for use in multisim, and I don't quite understand how the symbol editor works, but is it possible to make an interactive symbol, like a switch that opens/closes ?

I think I should be able to use spice data from a relay(modified) to get mine to work?

Just realized I might be using the wrong animation state stuff for the symbol I made since I made the symbol more like a switch (a couple) so the animation for a relay is different from what I used.

My symbol doesn't entirely work anyway, when I put puwer to COM1, the output ends up at NC2 instead of NC1, and NO1/NC1 don't work at all.

Hi GRNDPNDR,

It is not possible for users to be able to create interactive components. It is not possible to store interactive components in the User or Corporate Database. Sorry for any inconvenience.

Hope this helps.

well, that sucks and should definitely be a feature.

That aside, how do I go about making the symbol useable in simulation? is there anyway to have it still function like a relay even if the symbol doesn't animate?

as I mentioned, half of it works half as well as it should 🙂

Hi,

If you have the spice model for the relay, you can create the component by going to Tools -> Component Wizard and following the steps. If you use the component, it will function as it should but you just wont see its interactive changes.

A component creation tutorial is given in the link below:

Hope this helps.

Thats precisely what I did, and made a symbol for it but it isn't working quite right so maybe the spice data is wrong.

I originally made a circuit using 2xSPDT NO and 2xSPDT NC relays to make a DPDT. I used that spice data and had someone help me cut it down into a single model.

This is what I ended up with.

This is what happens when it's wired up in simulation, it should be clear that this shouldn't work the way it's hooked up so something is wrong with the model somewhere.
