Join all lines in a sketch

[jdaues]

I've created a sketch with lines. I now want to extrude but it won't do it. I think this is because the lines are not all one line. But I can't seem to be able to join them.

How do I get this to extrude?

Edit: I've been playing with things and came across Sheet Metal > Thin Extrude and it shows something is definitely not right with the sketch (attached 2nd file)

You can use thin extrude but you are going to run into problems as you line profile is not continuous as you suspected.  Try dragging blue lines a to see what is not connected.   The mantra from the experts is blue lines and white dots should keep you awake at night. 

You will have to make all the endpoints coincident. This may not give the results you want as nothing constrained.  Your sketch should be constrained to the origin and each line should be constrained.  If this is a repeated profile just do it once and pattern the extrude.  Then combine into single panel.

I added a small lip at the beginning so that the patterns would join correctly with the combine command.

just used your original file - others may have a better solution using sheet metal

This is usually covered in first five minutes of training.
