Hi, as I see, this question has been asked a million times, but here it is again.

I have a soldworks part and am trying to add extra features, but for some reason SW tells me that Sketch1, which I used previously for some extrude features, has open contours. I used Sketch repair and nothing showed, also tried Tools->Sketch tools->Check sketch for feature, and it tells me the sketch is fine, I even tried going all the way back to the first feature and creating new ones and had no luck.

Maybe someone can have a look and tell if the same problem replicates in their computer.

The area with the red circle in the attached image is one that I want to extrude and it won't allow me.

Thanks for any help,

Alfredo
