Trouble with extrusion
 

This should be really simple, but when I try to exclude my sketch of a circular sector, only the center is extruded as you can see from the preview below.

When I change the geometry to a test triangular I made right next to it, the extrusion is carried out as expected. What's going on? Thank you.

What is the error it is showing on extrusion? You can check it by right cliclking on the extrusion tree and select show error. May be it's open geometry...

There's actually no error. But I deleted everything in the sketch and started from scratch and it now works. Thanks.
