Almost all your sketches are underconstarined - fix that first. Make sure all things you want to be a face are really fully closed.
Extrude 23: No face selected, or the face selected was removed after you created the extrusion.
Sketch 17: There is one point way off (zoom out!) that has lost it's refernce. You probably removed something that was in fact still needed.
Almost all following sketches and extrudes: Same issue as with Sktch 17.
Warm hint:
sketch1 is SUPER "sketchy".
please comment your email and i will give access.
you've already given access. but you have not identified exactly what your trying to do and what errors your trying to fix. You will have to go into more detail if you want others to help you trouble shoot.
all of the remaining errors
sketch 10, 14, 27, 33, 36, 39, 40, 42,
extrude, 26, 11, 25, 13, 22, 45
revolve,1
If you open the features it tells you an error like this. in the case of sketch 10 and some others it looks like you changed something about Extrude 1 that caused sketch 10 to lose its connection to Extrude 1 face.
In your original document it looks like you edited extrude 1 on 3/17 @ 9:57 PM. This edit broke sketch 1. It looks like you deleted all of the sketch regions that extrude 1 was referencing to make extrude 1.
Link to the point in history to your original document before sketch 1 was broken..
