A suggestion re default values for chamfer and fillet tools

    Something that's been bugging me about Alibre since forever:

    When I start a new part and want to add a chamfer or a fillet the default value in the box is 0.25mm. This is really annoying as in the metric world we don't use fractions. I set my increments to 0.1 in the settings but it doesn't help if the starting value is 0.25mm.

    I know why it is 0.25, that's how the imperial system used by the US works. The entire rest of the world uses metric. Fix it please.

    A setting somewhere to allow the user to be able to set a default values would be the best solution .. or just remember the last value used as the value for a new fillet/radius!

    I also vote for last value.

    0.25 mm is as arb as using pi()

    Last value is better, since it gives a better chance that you will not need to change it.

    BTW.... Metric uses fractions all the time! 0.1 (1/10) is just as good a fraction as 0.25. There is such a thing as a 1.25 mm thread pitch, for instance.

    I'm just saying that a 0.25 mm chamfer seems a waste of time. That is better dealt with by a note stating to deburr, for that size. A minimum practical see size would be 2 or 2.5 mm. Anyway, not important.

    All depends on the size of the object you're modelling. You're assuming we all model big mechanical parts. For me, I 3D model electronic components where some parts are no bigger than 3 or 4mm, so even 0.25mm is a huge chamfer!

    I make watch movements, if I chamfer 2 or 2.5 mm the parts are gone.
    Finding a default value that works for everyone is impossible, last value is the best solution IMHO.
    (I have mechanical engineer collegues who think that the smallest screw size is M4. I tell them that a M4 screw looks more like raw mateial to me and they don't believe it when I show them a M0.4 screw. Different worlds!)

    Hi Hunter -- I am with you. I regularly apply a ".010 inch X 45° Chamfer" to "corners" of partss under the Feature Description "Break sharp edges (Typ)." -- Lew
