problem with sketch fillets on sharp corners.

[Anonymous]

I am trying to create a pattern of rectangles or slots and basically trim them all to the shape of an intersecting circle. I then need to fillet the intersecting lines, but I keep getting an error that just says "fillet cannot be created". I've tried breaking the lines, deleting them and then extending them, hoping that there was some artifact. It only happens on some and seems to be the acute angles. I can't change the radius of the fillet because I can't even get to the dialog box for that. It acts as if the lines don't even intersect.

If you have used pattern tool to create those rectangles, you need to delete pattern constraint first. After that other rectangles will act as you expect.

thanks, but I tried to delete the constraint before I started breaking and deleting parts and it still fails. only in one corner out of 4. Also trying a circle with tan-tan-center doesn't work, it won't even let me select the second line (the larg radius circle). I tried to see if it had to do with acute angle, but it doesn't seem so. Here's a nother picture of where it fails to make a fillet.
