I traced outlines from a photo for the shapes i want to use with splines. I then used the offset tool to offset the original splines that were used, removed depenancies linking offset to splines and then removed the original splines. I joined up the offsets to make contained shapes once more and saved it. I was then able to successfully use fillet tool as normal, however after a couple of hours i realised i put too many fillets in where they would not be needed. i loaded the file 2 versions before the lastest and before i started the fillets and saved with different file name so it was not read only. This time I am unable to fillet anything in my sketch, even drawing a perpendicular, straight L shape with all dependancies removes it displays the same behavior: Fusion 360 hamgs for about 5 seconds, then it errors with Error: Failed to solve. Please try revising dimensions or constraints. It is probably just a simple easy thing that i am missing as to why it worked the first time flawlessly yet now the fillet tool is not working at all.
