Using fillet between arcs

[Anonymous]

We are furniture designers, and we do a lot of work with flowing, serpentine curves. Splines don't work well for us; we use mostly polylines and tangent arcs.

When I have to change a curve, sometimes it would be nice to be able to do a fillet between two arcs... but so far, I have been completely unable to figure out how to do it. The program tries to, but the fillet always flips in the wrong direction- regardless of which arc I choose first.

Is there any way to control which way the fillet goes?

I have attached a file to show what I mean. Our old CAD software would do this right every time, so I know it's geometrically possible.

It all depends on where you pick on each entity, and the direction of the
curve.

I've found that if you can FILLET two entities you can also EXTEND then TRIM
them back too, a good way to actually test the fillet option.

Well, that's what I thought... but I seem to get that result no matter where I pick, or in what order. I've been experimenting off and on for a month...

How about Extend and Trim option?

For a smooth serpentine curve, I need to keep the ends of the arcs tangent to each other. Just extending/trimming them won't do that.

you could use a circle that's TTR tangent to one radius, tangent to a second
radius & has a radius of ??

Yep. That works. I still have to trim it, so it's a bit messier than a fillet would be, but it's better than nothing. Thanks!

Release 2012 is out already and this silly error is still not solved

Are you looking for BLEND? otherwise a fillet of two Arcs is subjective and a dwg would help others help you if there is a solution.

My method is: pick the desired radius for the fillet -> offset each arc by that distance -> draw a circle from the intersection of those two points with a radius equal to the desired fillet radius -> trim away.

This is an older post so I'm not to sure the OP will come back to this thread. 

But THANKS for sharing what worked for you.

Ik this is old but for anyone lost on this like I was and googled it, I realized you have to click on the RADIUS title in the COMMAND bar and set the radius BEFORE you select what you want to fillet.
