Project Intersection Curve no longer works?

Hello,

I have Autodesk Fusion Personal. I've run into an issue where suddenly I am no longer able to do the 'project/include' intersection curve. No matter what I do, I now get the error, "
Not support projecting sketch geometry into same sketch, please change the target sketch or geometry."

I understand it needs two independent sketches and I do not believe this is the issue. I have tried making the simplest 2 sketches on different planes and yet this error pops up. I have tried redoing a file that previously incorporated intersection curves, that worked before, and now those same sketches no longer work. I have re-installed the program and yet it still does not work. At this point, I'm at a loss. Is there a known issue with a software update? Any other suggestions?

Thank you,

Nevermind. I tried another file that previously worked with intersection curves and that file worked. It must be whatever I'm working on currently I have something wrong. Apologies, I'm new. Additionally, I'm not sure if I can delete a post. This appears to be a false alarm.

I can explain: It is there in the error message: "Not support projecting sketch geometry into same sketch"

While that is poor English and a little cryptic, it is trying to say: You cannot project a sketch curve back into the same sketch - you will have to create another sketch. This is because it needs a sketch->sketch dependency, and that cannot live within the same sketch as the source geometry.
