I'm trying to place a custom schematic component. The drawing is blank. What the heck is going on. (Image removed) \> Click "Place" (Image removed) I'm sorry, I don't understand that error message at all.

I don't  understand the error message either but it looks like you have created and are trying to place, is a Schematic Module not a Schematic Symbol.

Your schematic module component doesn't have a clearly prefix, you need to chagne it to SW1, not SW? ![图片.png](//image.easyeda.com/pullimage/rqCqGSMEJopcUFxJZdIotBFasFW176joX6HHIByK.png)

But then how will it auto-number?

@pretender42, As already pointed out, you have created a Schematic Module and not a Schematic Symbol so it will renumber according to the Schematic Module rules. It will renumber using the ? suffix only if you create a Schematic Symbol. Suggest you re-read the Tutorial to understand how to create Schematic Symbols and to understand the difference between Schematic Module and Schematic Symbol.

@pretender42, Because you have created a Schematic Module, when you place your relay into a Schematic you will not get the automatic PCB Footprint assignment that will pull in an appriopriate Footprint into the PCB when you do Convert to PCB... as you would for a Schematic Symbol. Reading (2.2) and (2.3) in (2) in: [https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a](https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a) will help you better understand the relevance and relationship between Schematic Symbols and PCB Footprints.
