I’m trying to get used to Rhino having different names for everything than the rest of the industry…
(Like “Fillet Edge” is apparently a G1 radius fillet, while a “Blend Edge” is a G2 fillet.)
Now… “Rolling ball”… is that a chordal fillet or not? I suspect it is in most cases, because tube offsets was what we used 15 years ago when normal fillets failed, but I believe chord width calculation is more exact, so is there a way to get such a fillet specifically?
Further, is there a way to get a chordal fillet with a minimum radius option?
inside the fillet options you have RailType = RollingBall , if you click there you have also DistFromEdge and DistbetweenRails which is the chordal fillet
Minimum radius measures the curvature surface of a G2 fillet and ensures that it’s not too tight at any point, if you for example need to mill the part you’re designing.
In Alias, it suggests a minimum chord length depending on the minimum radius you want to achieve (it’s quite a heavy operation since it needs to measure the preview fillet at every point).
Hello- for min radius, it may be more useful to set numbers than use the auto - for example, 1.6 max and 1.3 min will show you that fillet’s range of radii is pretty much right in the middle.
Diego, actually I think do have a thing that may help… let me have a look around.
@DiegoKrause - This can probably use some work but it might help - for instance as is, it only accepts surfaces, not brep faces - that should be easy enough to fix but it tells me I probably thrashed this out fairly quickly for some immediate task. At any rate it reports back max and min radius at the pick point and leaves a point object named accordingly so you can go back later.
