[sarik0031]

 I am unable to create a surface, even after seleclting these curve and lines. I think the profile is closed too.  Please help.

I've linked my file. Check it if necessary

Thanks, Can you suggest me techinques or tools to identify breaks in such sketches?

It's called divide and conquer in previous postings here.

Draw temporary lines across the outline, see which side turn profile blue, and narrow down to the problem connection.

Might help...

Actually, in 3d Sketch it doesn't turns blue, if I'm not wrong.

Correct, (did not know the sketch was 3d)

so, second trick is to double click the outline, Fusion will chain select all connected items to the selected entity.

Might help...
