1 chamfer is going the wrong way

I'm trying to add some chamfers to this model and I can't get the one edge to work correctly.  I can select and chamfer the edges one at a time, but that same edge is always chamfered wrong.  In the video I have all 3 edges selected.  2 are correct and 1 is wrong.  I want it to be 10mm at a 15deg angle.  (may change, but for now)  I've tried to make it 10mm at 75 deg, but I guess I don't know how angles work as 2.9mm at a 75 deg makes the chamfer bigger.

 

What is going on here?

The reason you cannot get the chamfer you desire, which I think is a distance by angle of 10mm x 45 degrees is because at these values, the chamfer will cut the model apart.  Take a look at the Screencast and see if you understand.  If you are trying to do a distance by angle that is not 45 degrees, you must apply the chamfers one at a time, you cannot select all three edges at the same time.

Looking a bit deeper at your situation, I can see your issue.  One edge refuses to accept the fillet like the other two.  This is a real problem that can only be solved graphically is by using a chamfer of 75 degrees and measure one of the existing chamfer offsets.  You model is attached.

The problem is that the "distance" arrow for one edge in on the X axis and the other edge is on the Y axis of the same face. It doesn't make any sense to me why the arrows don't go in the same direction on a face. The direction should be able to be flipped to suit the user. 

You can use draft to get the result that you want but like many things in fusion there is a trick you need to know to select more than 1 face at a time for draft. It is easiest to select the faces first and select the plane second, otherwise it is difficult to select the faces after the plane, you need to hold ctrl to get the other faces to select and you need to click a couple of times to get it to select.

I've run into the same thing numerous times in Fusion 360.

Image: I added 4 chamfers, 0.03inches, 75 degrees.

3 go one direction, 1 goes the other way. The quickest way I've found to "fix" it is to leave the 3 good ones, and then create a separate chamfer feature.

Just FYI - this bug is high on our list to fix this year.  The fix will require you to select a reference face from which the angle is measured, or to distinguish the two distances for a two-distance chamfer.

Attach your model so we all can see the problem and verify it.  If you do not know how to attach your Fusion 360 model follow these easy steps. Open the model in Fusion 360, select the File menu, then Export and save as a F3D or F3Z file to your hard drive. Then use the Attachments section of a forum post to attach it.

Currently experiencing the same thing. It's weird because it literally worked a few minutes ago then I deleted it and tried adding it back now the arrow is facing the wrong direction

Hi,

Are you sure that the edge is part of a single body? If it represents the contact edge of solids, a connecting chamfer cannot be created.

 

Please share the file.
