I am trying to extrude to make a fin (the half heart shape). I have tried adding another sketch line to complete the "circuit" but that turns black and my blue line stays the same. Thank you.
Extrude
If I am reading your model correctly, your sketch, of the heart shape, is on the wrong plane. If my return model is what you desire and you cannot read the timeline, let me know and I will do a Screencast. The heart shape is a spline and it is very difficult to fully constrain a spline. Key points can be dimensioned but that is about all you can do. I extruded it the fully length of the other body but this can easily be changed by editing the last extrusion in the timeline.

Is this what you're trying to do? Then you don't need to make new sketches, just draw the spline in your first sketch so you'll get a closed profile:
Thank you both for helping. Not exactly. I am trying to make 3 individual fins like this.
First of all, you can use one sketch for multiple extrudes (though it's not usually recommended to make complicated sketches):
If you need 3 fins, then use Pattern:
If still this is not what you want at least show it with a hand sketch.
Not quite. My question is in this picture, the highlighted blue, why cant I extrude? F360 wont allow me to highlight it. I have done something similar and was able to make fins but I changed the design a little at the top.
OK, I was able to accomplish my part. Thank you all. I am understanding better now. Thank you.
Accepted solution
You can use Pattern, as I suggested in my previous reply. I also changed my previous file by doing Extrude and Pattern in two directions symmetrically. Check the attached file. If you need the fins to be separate bodies change my operation type in the second Extrude from Join to New Body.
