Extrude a mostly mirrored sketch doesn't work?

Hello,

I have created a sketch for an aluminum system profile. 1/8 is drawn (meassured part) and the rest is mirrored. Unfortunately, I can not create extrusion from the sketch. Only why is not clear to me.

    There must be a gap in your profile somewhere - if the area is shaded then it is good for extruding. A trick to find the gap is to draw a horizontal (or vertical) line through the sketch and drag it up and down to see which areas of the profile are shaded or not.

    Great tip. But I can move the line arbitrarily and all partial amounts are represented as gray area. Only the whole profile not. Is this perhaps a bug?

    Not a bug - keep searching. You could also show constraints (in the sketch dialog) to see if there is a coincident constraint at each vertex.

    @ralf, Can you share your document link with us so we can look into that issue.

    I think I've encircled the error, but I do not understand it. It seems that the point in the rectangle is the problem. But why? All the other mirrored points are working?
