Does anyone know of a way to chamfer smooth corners from a vertex ?
I generally have to chamfer, divide, then move the vertex’s for the curve shape.
It’s a bit tedious and not precise enough. I know polytools has the loop functions , relax, curve etc, is there anything similar for vertex ?

thanks

sheesh , never mind , I figured it, extrude face then chamfer the corner edge, delete what I don’t need.

I’m not getting the sizes that I want. If I type 30 mm it becomes 42 mm when I test it with the measure.
That if I’m using a chamfer in an edge.

Jacob, the measurement in the chamfer dialog is the radius of the chamfer curve measured from the centerpoint of the curve (green in the image).  You’re measuring the cordlength from where the chamfer begins to when it ends (blue in the image).

The equation to find the cord length that you are looking for is dictated by the Pythagorean Theorem, which you may remember from your geometry or trig classes.

A^2 + B^2 = C^2

If you plug in the numbers:
30^2 + 30^2 = X^2
(30^2 + 30^2)^0.5 = X
you get
X = 42.426…

To get the radius required for your cordlength of 30mm, you would use this equation:
(30^2/2)^.5 = X

If you are using a version before 3dsMax 2011 (before they created the much hated caddies), you can instead of entering a number into the chamfer amount text field, press the ctrl+N keyboard combination which will open the “Numeric Expression Evaluator”.  Inside this dialog window, you can enter the following text for a cordlength of 30:
(30^2/2)^.5

if you wanted a cordlength of 55.5, you would enter
(55.5^2/2)^.5

If you want to use the equation above in 3dsMax 2011, you could create a sphere, for instance, and use the numeric evaluator in the radius parameter and just copy and paste the result from the radius of the sphere to the chamfer amount of the chamfer.

Hope this helps.
