I’ve been designing HMI/SCADA screens for a very long time, and never have I had two customers agree on what constitutes “good” graphics. Everyone has an opinion.
To expect a “standard” Perspective Symbol to meet everyone’s expectations is not something that can be accomplished. It’s just not possible.
The best thing about Ignition is almost anything is possible, including making your own custom .svg graphics. Ignition 8.3 now has a drawing editor, which I have found to make .svg customization tasks much easier.
…and if you are really adventurous (or just hate drawing as much as I do) then start training your AI agent to make the symbols exactly like you want.
I’ve was experimenting here, and @Nol had some good feedback on how to do it better.
