❓Why isn’t my custom component showing up as an option in my project?
- If you can see a meter inside your Component Editor but it doesn’t appear as an option when you are working on an active project design, it is failing one of these four rules:
- **It isn't compatible:** If your project design isn't compatible with this specific product, you won't see it as an option. Check the specifications you have set in the 'Electrical' tab for your component.
- **It has been hidden:** Hiding a meter removes it from your dashboard view *and* completely disables it from the Electrical task selection. Check for hidden components by clicking **Filter** and toggle on 'Show hidden'.
