Why can't I extrude this surface?

Hi,
Although this surface is closed I can't extrude it.
I assume that it has something to do with the fact that the side lines come from another sketch from which I imported them into the current sketch using Use.
But it should be correct, otherwise the surface would not be closed!
Kind regards

P.S.: by magnifying the drawing I have found and eliminated the problem and I now may extrude.

I'm not sure what term would be for why the extrude wouldn't work. what I did find was a confusing abundance of overlapping and close to overlapping sketch entities. If you go back into sketch editing and right click on a sketch entity, select 'Select other' as the option you'll see all the entities available. At some entities it can be understood that there may be some 'confusion' as to what exactly is to be extruded. I deleted the unnecessary elements and from there repaired the remainder and it did extrude. - Scotty

Thank you for your help!
When I zoomed in a lot I noticed that there was a lot of clutter in the lines.
I deleted a superfluous line and it worked.
But what I don't understand is that if a surface is closed, which you can tell by the fact that it is colored, then everything should be clear and it should be possible to extract it.
Yes, when I first looked at it, I thought: 'that oughta work'. Perhaps with all those conflicting lines it also added 'conflicting surfaces'? Dunno. Perhaps one of the gurus will chime in. - Scotty
ok, thanks
Having a similar issue, having rotated a parametric curve (full rotation). Thicken works, but the 2nd surface doesn't match the math for the original surface (I need an exact profile). I also tried copying the original surface and then filling between the surfaces, and thickening downward from the original surface, which would preserve the math I need for the upper surface. Thicken doesn't like to go in a negative direction, and I wasn't able to select the bottom of the surface and then thicken down (instead up thickening up from the top surface). Not sure why "thicken" can see my surface, but extrude seems to only work with sketches.
The "direction" fields for some of these (extrude, thicken, etc.) would be greatly enhanced if you could just pick an x, y, or z direction and input the distance. Instead, they often make you click on the planes at the origin, or select a mate connector, etc.
As a very new user with admittedly very little time learning the tool, I'd say my experience has been characterized by things that could be made very easy for users not working for unknown reasons. Would be great if the devs could observe what us newbies are trying to do, might give some insight into how people expect to use the tool and what the stumbling blocks are. It certainly has great potential.
