with NTST installation comes a pretty complete library of symbols, accessible through Symbol Manager under Windows menu. I'd like to use these symbols as label for a touch button or for a lamp, but apparently this is not allowed. I also tried pasting a symbol in a screen and then drawing the object around, but the final display is far from ideal. Is there a way to use these symbols the way I described, or they are intended to be used just as static pictures?

I have never used them, but it looks you have to register the symbols als a library object, whereafter they can be selected for an image lamp.

1.Open Window > Symbol manager
2.Open the library, look up and copy the symbol you want to use.
3.Open Tools > Library editor
4.Create a new entry
5.Paste the symbol

Now the symbol can be selected in an image lamp by the "Change library" option.
Is that what you mean ?

thanks for the image lamp procedure, for me however it would be more useful inserting these symbols into touch buttons, as a way to keep panels' software as standard as possible. So far it seems to me that I only can have text or marks, and cannot paste symbols as marks.

No that isn't possible. But you could use blank buttons and place the image lamps right next to them?

I am trying to put icons in touchbuttons to do away with many translations, so putting image lamps besides them is not what i would like. I tried all yesterday to impose an image lamp on a touch button, and although it works, when the touch is pressed the area around the image lamp remains "black", i.e. not evidenced. Considering I am working on an old machinery with NT20 installed this is perhaps the best I can get from such hardware and probably what I will end using.
Thanks for your hints about a part of software that I was definitely underusing so far.
