Visio - Do these shapes exist?

[arthurkam]

Hello,

I am trying to make a vacuum diagram with Visio and I know there are valve shapes and whatnot.

Are there shapes for specific pumps? Such as Diffusion pumps, rotary vane pumps ...

If they are not built in, can there be add-ons or downloads available for them?

Thanks!

The Symbol Factory has all that - good but not free.
