Fillet with 2 simultaneous radii

Brob Lamparty Sep 17, 2013 2:36 PM

I recently came upon a model that had a fillet that was constant, but constantly two radii. I can't find the model, but I drew a sketch to indicate what I mean.

I drew this sketch pretty quickly, but this is basically a cross section of the fillet. An inspection of the curvature showed that the radius was constant in the two sections, but changed from one radius to the other at a specific point along the fillet. Is there some way to easily re-create this feature or was this created using lofts and other surfacing tools?

Thanks in advance for any help.

I have never seen anything like that in SolidWorks.

If you really wanted that, I would use surface sweep, and it would all have to be done manually. There are new fillet options in SolidWorks 2014, but they allow for conic shaped fillets, not two fillets of fixed radii.

Brob, do you remember seeing an edge in the middle of the "fillet", where you have the contact point between the 2 arcs?

  There was a line where the radius changed, but no noticeable edge. The radii of the two fillets was rather different, and I think that allowed for the appearance of a smooth blend.

    Brob,
    
    What do you mean there was a line, but no noticeable edge?
    
    If there was no edge, it could still have been made with a sweep, but the two radii could have been replaced by a Fit Spline.

maybe there was a step in the corner so he could put two different sized fillets? or was it one feature. If it was one feature i believe it would have to be as charles said a swept boss or surface.
