can't get dxf to press pull. and missing cam paths.

[Anonymous]

Good mornin, i can't get this dxf to press pull. I checked the through all the lines and can't find any that are disconnected. Even used sketch checker.  Also even when i try to cam it for plasma cutting it leaves out a bunch of stuff like the shoelaces etc. Any help is appreciated thank you.

why won't the forum let my upload the file?

You will probably need to zip the file before it will upload.

Hi,

you can also upload the f3d file with included dxf.

figured out how to zip the file. Couldn't on the fd3. Im dealing with this on multiple dxf's.  

[ryan.bales]

So a few things. The dxf itself press/pull extrudes just fine. What i'm seeing is that most of the fidelity of hte sketch is lost on extrude because the lack of closed profiles. You'll need to find the profile that is open and correct the issue for it to import extrude properly. 

Even when importing it into AutoCAD many of the profiles show as open.

I tried following the lines and couldn't find where it was open. I tried to download sketch checker from the fusion app store and when i download it just goes to the bottom of my chrome browser as a pdf and i can't do anything with it.

There is an anomaly in one of the lines which causes Fusion 360 to not recognize it as a boundary.  Find it using the Divide and Conquer method.  This is simply draw a line bisecting the geometry.  If one side is good, repeat on the bad side until the problem is found.  Avoid drawing lines to or through other endpoints.

Note: There are other spots which aren't resolved as boundaries.  Check the buttons.

I can't repro the CAM issue:

I was usuing .07 kerf and .06 lead in and when i simulate its skips a bunch of stuff. thanks.

[Anonymous]

I'LL give it a shot thanks.

.07 kerf is larger than some of the features.  @ryan.bales What is the expected behaviour when this occurs?

[ryan.bales]

Short answer is the kerf is too big. I would imagine it would skip anything that it can't cut as the kerf is too large. 

Also i'm not sure leads are required here as it's adding to the ^ problem.

I did 0 lead ins last night and .3 kerf just to play around and It still wouldn't cut some spots. the rectangle above the shoelaces wouldn't even cut and thats pretty big. If i click on the face and let fusion create the toolpath vs clicking each feature it will cut everything. but anytime i've ever clicked the face it cuts terrible for some reason. thanks.

Found the broken line!!! thanks. now for some cam fixes.

 got it into a solid but fusion won't create any kind of a cam file. can one of you  try please?  Comes up with this error.

Error: Internal CAM kernel error. Please report through your support channel.

@ryan.bales The error repros on my machine.  It seems the model is too complex for the CAM solver.

@Anonymous Breaking the toolpaths down to smaller sections will allow you to machine almost all of the model.  Try setting the parameters as small as possible.  If there are features that still can't be machined, then you'll either need to remodel them or not machine them.

[ryan.bales]

I get the error too, but if i shut of leads and compensate in computer it does generate - albeit leaving out items smaller than the kerf. Your workaround is by far the best, remodel and break it down into a few operations at least.
