Break Command not working in Fusion 360

[RGache]

The break command to break up lines and the intersection of lines with other sketch geometries does not work in my fusion 360 product. For example, when I sketch a circle and then draw a line across the circle, the break command does not activate when I select any or all of the geometries. I have checked support and forums on this, but this appears to be aberrant behavior in the program. Is there some general setting that I need to enable to allow the break command to operate? Please Help.   I have attached a file that exhibits this unexpected behavior.  Russell Gache

that case seems to work OK for me.  Can you supply a model and a video showing the case you have where it does not work?  Thanks.  Sorry, screencast is not behaving today, so this is just an MP4 video

[jeff_strater]

OK, here is the screencast:

Ok, I will try to upload a file and screen shot.

Have you Moved geometry off of the 2D sketch plane?

[RGache]

Saw it! I know, it looks so easy, but my version does not do that. It like its turned off or something. -no red x's, no selection of portion. Thanks for replying. I guess my version is broken is broken. Uninstall and re-install? Is there any global settings or anything that you can think of? Very frustrating. I love/hate F360. R

Crap, maybe.  I oriented the sketch along the z plane because I wanted to 3d print it using z as the height.  But, as long as everything is in the same plane, why would that matter?  I will try using x/y plane and see if that makes any difference.

It has nothing to do with the version.  That command has not changed in years.  Please share the model here.  We can't really help without seeing your model.  As, @TheCADWhisperer said, it could be the geometry is not on the sketch plane (3D sketch), in which case Break will not work, or if the circle and the line are in different sketches.  But, without the model it's just speculation.

Can you File>Export your *.f3d file to your local drive and then Attach it here to a Reply?

it should not matter what plane you picked for the sketch - XY, YZ, XZ, a model face, all will work,  What won't work is if you enabled 3D sketch, and sketched away from the plane you picked to create the sketch.

[RGache]

No, using the x/y plane does not help.  drawing a line across a circle does allow for breaking, NOR TRIMMING, of any geometries.  But, everything else works!  -R

[RGache]

I have attached the file.  Thanks for all the help people!  -r

[jeff_strater]

can you record a video/screencast of your session, from the very beginning?  Start with creating the sketch, drawing the circle, then the line, then trying Break.  Or, share the model here.  Thanks

Sorry, posts crossed paths.

Thanks.  This is what I was referring to above.  You have 6 different sketches in this model.  Some are empty, some have just one curve.  But, looking at the circle/line example, the circle and the line are in different sketches.  When you want to add geometry to a sketch, use Edit Sketch, don't create a new sketch.

Screencast coming whenever Screencast decides to wake up again...

here is a screenshot of the problem:

[TheCADWhisperer]

Sketches 18 and 19 are different sketches?

Sketches 1, 14 and 16 are different sketches?

[jeff_strater]

and, here is the screencast:

Yes, thank you--all.  The confusion is that I assumed that I could finish a sketch as as long as they are on the same plane I could trim them and break them up.  But, you can only do that for a single sketch and only when you are either still in the sketch creating it or if you go back and then edit the sketch.  Total newbee confusion, but yet one of those basic things that no one mentions in the learning videos.  Thanks to all and I hope this helps someone else!  -R
