Hello, When I create a new symbol in a local library, I don’t see the symbol I created as if the local library does not open. What am I missing ? TIA ---

Hi and welcome! Probably you only created a _symbol_, which is not enough. You also need a corresponding _component_ which references your symbol. After that you should update your project library. Now you can use it within your project - at least for the schematic editor. For the pcb you also need a package and device - but this can be done later. ---

Thanks sasmus ! I thought I had tried that but I will check again. Maybe I didn’t update the library ??? FMI, For schematic only, do I only have to define the component ? ---

Yes it works! Another question : when I change a symbol used in a schematic how do I update the schematic with the modified symbol ? ---

Just update your project Library! ---

Thanks again ! May I ask what is your job. Do you use librePCB to produce complex PCBs ? Before I retired (2001) I was in charge of CAE/CAD tools for Alcatel switching division. We used Viewlogic, Zuken and Mentor tools ---

Well, no. I’m doing this for hobby purposes only. Decided to give LibrePCB a try because an other EDA tool i used until then is no longer maintained. In professional life i’m an engineer designing wide area networks.
