Sketch fillet on acute angles flips after click

[sundewzer]

When I am hovering on the point the preview red line looks corret. After one click the fillet seem to not have a tangent on one end of the curve. Then on the second click it flips the first fillet and when I click ok it flips the second fillet. I have tried selecting the point and different line in a specific order and I can control which way the fillet flips but I can't get it to work right. It is easy enough to fix but sort of a pain. I also tried different radii but still messes up. 

Anyone figured out how to get it to fillet correctly?

Hi Casey,

Sorry about the problems you're facing with sketch fillets.

I'd say it's best practice to keep sketches as simple as possible and add fillets as features on the solid model instead, are you able to do that?

Could you please send me the f3d file or share the design to me?

thanks

I couldn't figure out how to export the f3d file, here is the link.

I was tought that it is less resourse intensive to put as many feature as possible in sketches instead of aditional feature. I was told that when a file was edited or rebuilt that it would take longer the more individual feature there were. This was training in solidwork though, is fusion different?

Hi Caser,

Thanks for the file. I can reproduce the problem. I logged a bug(FUS-25479) to track the issue.

As workaround, we can create the fillet manually, firstly launch 2-tangent circle command:

Create two circles, and add dimension to one circle, add equal constraint to two circles:

Trim the circles and line segments:

Now we will get the fillets:

We will investigate the bug and try to find a fix. Sorry for the inconvenience!

Your SolidWorks training was incorrect, or you misunderstood the instruction.

It is generally preferable to add fillets as features rather than in sketches in any history based modeler, including SolidWorks.

I can find multiple sources of expert information on this if needed.
