Missing Perspective Symbols

Using Ignition 8.1, I can’t find several symbols shown below such as positive/diaphragm pump, pneumatic valves etc…

What am I missing?

Those Perspective Symbols aren’t missing—they just haven’t been implemented yet. There are still plans to add more Perspective Symbol components in the future, but there is not currently a timeframe for their release.
