SW 2015. I'm having some trouble understanding and controlling Auto Relief. Have a look at the attached file. You'll see that I've specified an Obround relief with a width-to-thickness ratio of 2. The thickness is specified as 0.090, so I would expect the relief to be 0.180 wide. In fact, however, it's much larger then this. Looking at the flattened part, you'll see that the relief is a square with rounded corners. The relief ratio seems to control only the radii of these corners - the straight sections connecting them remain the same length. What's driving the length of these straight sections?
