Hello,

how can I create a variable fillet with radius 0mm (right) to radius 8mm (left) along the curved intersection shown in the attached picture?

Hello Skipper,

maybe you can use the variable fillet option (new point set -> add the endpoint of curve, check box linear blend, click on current pointset, set the radii). If this is not working for you - the hard way. Create the intersection curve, place a circle to the end of the curve. Make a sweep with pointy end. Trim both surfaces with this "cone". Make a blend between the edges at the gap.







I hope that helps!

Have a nice day
Karsten

Hi skipper, you can use variable radius fillets by expanding the "Fillet set" section in the fillet options, and adding in a new point set by picking points on the edges. Once you have defined a point set, the next radius you enter will control the radius just at those points.

So for your case wanting to go from 8mm to 0mm, you'd start by typing 8 and push enter to set the main radius to 8, then expand "Fillet set" and add in a new point set, click the spot on the edge that you want to have 0mm at then push "Done" (or right-click in a viewport) to finish picking points, then enter 0 for the radius to be associated with that point.

There is a demonstration video for variable radius fillets here: http://www.youtube.com/watch?v=CemIL-wleOw

Sometimes 0 radius can be difficult for the fillet engine to handle though.

If you're still having problems, please post the 3DM model file instead of only a screenshot.

- Michael

p.s.: I agree with Brian, it's always better to have the file, to see the particular problem:-)

Thank you,

"the hard way" works fine and is pretty straight forward.
