Is there any way to access everything in symbol factory while using trial mode to develop projects?
Nope. You’ll have to purchase a full Vision license.
I think you just need a full Symbol Factory on your license.
The licensing restrictions on Symbol Factory aren’t controlled by us; you get 1 symbol per category during the trial or all of them if you buy it.
how do you buy the full version?
Isn’t it part of the ignition designer?
No, Symbol Factory is a separate module that makes their collection of SVG files available in the designer.
As for buying it, talk to a sales rep I guess
