Remove "derived from symbol"

[Basilisvirus]

I want to remove the “Derive from symbol” property (or set it to “None”). But there is no such option when on the drop down menu:

Is this a bug? The description text next to it says “…or select None for the root symbol”.

The “Derive from symbol” property needs to be set in the “New Symbol” pop-up menu.

To do this:
Select your symbol “TH”,
Highlight the library in which you placed “TH”
Select “New Symbol” icon
Edit or delete anything in the “Derived from existing symbol” box.

The “Derive from Symbol” line in the “Library Symbol Properties” may only be used to change a symbol from the available selection in the drop-down list shown when clicking the right hand arrow.

The pop-up instructions are not very clear.

@jmk

Edit or delete anything in the “Derived from existing symbol” box.

THank you for the reply!

When I follow your instructions KiCad just makes me make a new symdol, it does not edit the one I highlight:

Where “derive from existing symbol” is already empty.
Are you sure your suggestion works as you described? can you show me a screenshot how it looks on you?

[jmk]

That is correct. Type in the symbol name “TH”.
You are copying the new “TH” into the same library as the old “TH” but with the “Derived from …” empty.

When you “save”, you select “overwrite” option, so the new TH without derivatives replaces the old TH with derivatives.

Sorry, I assumed a bit too much with the original comment.
