Hi Everyone,
I'm trying to expose some copper on a copper pour.
Want I'm doing:
1. Setting Layer to TopSolderMaskLayer
2. Use Solid Region to draw area I want to expose copper.
3. Clicking on edge of new Region to bring up properties.
I can see Expose Copper button. But it is grayed out. I don't know want to do. Ivé send a lot of time on this design, just to hit a road block on the finish line. 😒

Thanks for the reply.
The region I drew is the same color as the other pads on the board. Did I do it right and didn't know it?
I'm using JLCPCB assembly. I've had trouble with this before using them. I just want to be careful. This order is going to be over $200 and I'm a bit nervous.
Thanks,
Dan
Your project is private so only you can see what you have done.
At the very least you must check the Gerbers using gerbv as advised above.
For best results, please read - and then follow the Essential Checklists (4) and (6) in - (2) in:
Brand new interactions and interfaces. 
Easy to use and quick to get started. 
Draw the shape you want to expose in a Copper layer layer then the Expose Copper button is enabled.
Or:
Draw the shape you want to expose in the Top Solder Mask Layer. This will create an aperture in the mask.
Check it in the Gerbers using Gerbv.
