Bore Toolpath not generating today

[ed]

Existing program, none of the Bore toolpaths will generate this morning.  No errors.  Anyone else having this issue with the latest build?

@ed Is this turning or milling? Can you attach a file?

Thanks,

Milling.  Can't share program publicly.

So problem seems to be related to the selection of the hole geometry.  The bore and thread toolpaths use the "face" of the hole to select.  That is also showing as a problem for a simple drill toolpath, but the drill toolpath is cured by selecting the geometry via point instead of face.

I bet you a million bucks (which I don't have) that your holes are NOT in line with the active Z axis. You can prove this by turning on Tool Orientation and selecting the cylinder as the Z axis.

Is this a native Fusion file or an imported one?

[seth.madore · Accepted solution]

File received.

So, it's a fully native file. However, there seems to be a modeling error:

After some additional investigation, I don't think this is user error, but something going on in Fusion. I've encountered this more than a few times in the last couple of months, but it's always been on imported files from other CAD packages

The error is so small, just use tool orientation aligned to the Z axis of the bore

SOLVED - kind of.  This issue is a bug in Fusion which has certain geometries ever so slightly not inline.  There is an angle between the bore and the tool orientation by .000002 degrees.  Fusion tech said they have been seeing a lot of this the last few weeks.  I changed the tool orientation Z to the bore and not the flat surface and it generated successfully.  Referred to development.

That's....basically what I said. Yep, tickets have been logged.

Hey ed, this should be fixed in our latest product update we just released (2.0.9849).

Hi all,

Just found this thread by searching "Fusion 360 2D Bore Nothing to Mill".

In quick summary, I am collaborating with someone who is designing a part in CATIA and I am machining it.  Of course, I use Fusion 360...

I have received the model as both .STEP and .CAT

Upon trying to select features to bore, everything goes well until I "OK" the Bore operation and then I get the Yellow Triangle with the Nothing to Mill error.

Seth's workaround solution works by setting the tool orientation to the bore.

I can't seem to prove the angular error by any combination of selections with the Inspect tool.

So...as of 1/30/2022, not exactly "fixed", but I appreciate the workaround!

@TJS01 could you share your Fusion file?
File > Export > Save to local folder, return to thread and attach the .f3d file in your reply

[seth.madore]

@TJS01 I've received your file and responded via email. Don't set your Z axis to that outside edge, it's "off", ever so slightly from the bore. Rather, set it to either the center bore or top face of the part.

Thanks again!
