Cannot extrude simple Square

[ElonMusk]

Hey I have made this square using symmetry and for some reasons Creo doesn't recognize it as a closed loop(but doesn't tell me where) and won't let me extrude it....does anyone know why this is?
I have attached a photo; for some reason I couldn t attach the source file though

Hi,

I guess that your section contains overlapping lines.

Note: If you want to upload mypart.prt.1 then I suggest you to pack it into zip file, eg.  mypart.zip and attach this zip file to your reply.

Well the problem that Creo doesn't show me any intersecting lines and I don t see how there can be any, as it is such an easy form. I have attached the source file below 😉

Alright it should be good now.
Thanks for helping me btw 😉

On something simple, I will typically just delete a line at a time and undo until I find the one that i sketched twice.

Or more likely, I will just delete all of them and resketch. For a rectangle, use the rectangle sketch so you don't accidentally double up a line or the arrow next to the rectangle to get a centered rectangle.
