plot an expression in sim

mattbrownduke — Wed, 03 Jun 2020 20:12:29 GMT

Is there an easy way to plot an expression in simulation. For example, I know I can plot a voltage, say I have a couple of nodes N_1 and N_2. I can plot V(N_1) and I can plot V(N_2). But can I plot the ratio V(N_1)/V(N_2) ?

I know how to do this in other software. I seem to have lost the ability in Fusion 360. I want to know how to do this in Fusion 360.

Thanks!

Hello @mattbrownduke,

I hope you're doing well. This is currently not possible in Fusion360. Thank you for the feature suggestion.

Let me know if there's anything else I can do for you.

Best Regards,

Thanks for the confirmation on this one, too. Leaving unsolved as a feature request. Not everyone wants to plot expressions, but when you need to, you *really* need to. For example, it's necessary in at least one technique for doing phase margin analysis. One competitor, LTspice, makes plotting expressions really easy.

I can think of a workaround to get it done in F360, but at that point I'll just use LTspice instead.

Hi @mattbrownduke,

As someone who designed power supplies before working here I totally understand where you are coming from. Thank you for posting the suggestion, as more eyes see it, the more likely it is to be addressed soon.

Let me know if there's anything else I can do for you.

Best Regards,
