Dear Sir/Madam,
I have one very important question. I am a student doing BTEC level 3 in aeronautical engineering. I am actually designing an aerofoil of an aircraft wing by using SOLID WORKS2015. All the information is correct about the coordinates and there was a little gap between the two points at the trailing edge so I drew a line there to fill that gap but still I was not able to extrude it. I am really confused about this extruding problem as I have not used SOLIDWORKS ever before. I hope that you will answer my question as soon as possible. I will be waiting to your reply.
Thanks.
Kind regards,
Haider Ali
There might be a small line segment in your sketch that is not part of the profile. Look at your line intersections closely and see if there are any tiny lines that are not connected to anything else.
I hope that helps!
