Fillet problem. It may be a bug in fusion360

[Anonymous]

look the picture and the file.  it is a simple shape.   But i meet a trouble in filleting the edge.    then i try the same shape in solidworks--everythings is OK.

Is this a bug in fusion 360?

Please Attach your *.sldprt file here.

Did you faithfully recreate the geometry in SolidWorks as native SolidWorks geometry?

Or did you run this geometry through a neutral conversion to open in SolidWorks?

If I Export the geometry as STEP (*.stp) and then Open in Autodesk Inventor Professional (the Autodesk equivalent product to SolidWorks) I am able to Fillet that edge.

If I open the exported STEP in Fusion 360 I am able to Fillet that edge in Fusion.

Well, no file and I am going to bed.  I will check back tomorrow for your *.sldprt file with native geometry.

I am able to fillet this if I use a different construction method.  Instead of sweep, I extruded the side curve, split the body, and removed the top half.  Then re-applied the fillet on the corners, and I'm able to add the fillet.  We will look at why it fails using sweep.

@jeff_strater: But you're not getting the same body, unless your front face is straight and not curved.

As @JDMather has already mentioned, if the geometry is exported a .step file and re-imported into Fusion 360 it fillets fine. That would mean to me that there's sometime wrong with the geometry in the .f3d file.

1. I am not sure I understand the point of showing that creating completely different geometry allows the Fillet.

2. It is interesting that "washing" the original geometry through STEP allows the Fillet to be solved.

Change your Sweep's Orientation setting to Parallel instead of Perpendicular.

sorry, it was late, and I was in a hurry.  I thought the profile was just a rectangle, didn't notice the arc.  It seemed like a silly way to just split the face.  Anyway, the point really was "We will look at why it fails using sweep".  Apologies all around.  You can turn off the fire hoses now...

Sorry I just saw your reply.

I do not know what the reason, I can not upload files, so I recorded the operation process into a video to send it

Then log back into the forum with your other username, go to my post, and click on the Solution button so that it will be marked as such in the thread.

Done!

@Anonymous Just be aware that the different form of sweep results in different geometry.

Hi everyone, thanks for all the input here. I feel uneasy about the different geometry as well so we'll have a deeper look at the problem (internal ref ASM-6647).

Cheers,
