Hi Burr, yeah there's a new "Calculation failed" message that will be generated if nothing was able to be generated by a command.

It's not in place of any previous fillet behavior, it will still try to allow partial fillet results if possible. The new message will only be displayed if there was nothing generated at all from the current operation.

The way it used to work was that if you were inside the fillet command and adjusting the radius value, if the value you just entered did not produce a result nothing happened at all which means any previous result from prior radius tweaking would still be visible on the screen. That was kind of bad because it could sometimes be hard to tell whether you actually got a new result or not.

Now when it fails to generate something, it erases any previous result (so the original unfilleted object will be displayed) and will give that "Calculation failed" message so it's easy to know that you're not looking at some "stale" previous result.


The old way was particularly bad if things were taking a while and you left your desk while it was chugging away, when you got back to your desk if it didn't say "Calculating..." anymore you knew that it was finished but it was not entirely clear if it had failed or not. The new way should clear up that particular scenario I think.

Let me know if this doesn't make sense or doesn't match what you are seeing.


It should work like this in every command now, not just fillet - if the command did not generate any result you'll get that "Calculation failed" message.
