I’m blundering through creating some library components. I had things working but I couldn’t connect the wiring. I then found that I had to add pins to the component symbols. Now I get the above error when I try to place a component in the schematic. How do I fix this? ---

It’s hard to tell the exact fix without knowing what you did _exactly_. But I’d suggest to remove and re-create the **symbol variant** in the component editor (it is typically called “default”). Then save the component and try again adding it to the schematics. If this doesn’t help: - Try updating the project library (Project → Update Project Library). - If the symbol has already been added to the schematic previously, remove all these instances from the schematic and re-add it again.
