fillet problems

 From:  armin
Hi to All,

Today I ran into some problems with fillets. The first shape at the origin was my starting point. On the second shape I used a fillet of .005, which caused some unexpected extension. On the third shape I used a radius of .01 which looks much better, but if you zoom into that "corner" you can see that those lines do not perfectly connect and on the opposite side there is a weird wave. I noticed the same problem on the curved face at the very top, the edges of the fillet do not really meet in one point. If I zoom in on the original part, those corners look perfect.

Thanks in advance
