I seem to be missing a step since I’ve had this problem before. Right now I have a polygon a drew with all lines, and I want it to create a face on a flat plane, which I can then extrude.
Before my issue was that the line had gaps in them, so I downloaded the edge tools and had it check for gaps, but there is none.
What am I not doing?
