Exported DXFs have broken lines

Exported DXF has misplaced lines as viewed by several programs. There seems to be no actual solution in the forums, these threads go dead. What's the issue  here?

The video will outline a process that will work for you.

The problem with this is that the bend lines do not translate to Send Cut Send, for example. What would be the best solution here? 

Converting the projected bend lines to center/construction doesn't seen to work, only thing I could think of trying.

I am not familiar with the application you mention.  The Bend Lines can be exported with the DXF as the video shows.  Maybe you need to change the linetype for your application to recognize them.

Changing line type doesn't solve it.

SendCutSend.com, one of the most popular laser cutting services out there.

The site you mention asks for the bend lines to be solid lines.  The process I gave you gives you solid lines so I do not now what to tell you.  Maybe you should call the site number and ask.

Why don't we focus on finding the actual problem with F360 on this flat pattern instead of a work-around?

I gave you a solution, verified what the website is asking for which the solution will give you, there is not much else to say.

What's problematic is that creating a sheet metal body from the derived sketch still produces a broken DXF file, even if it rebuilds the bend lines that SnS for example can now find again. 

Fusion is bugging out on creating what is, in reality, a really simple flat pattern and knowing WHY and how to PREVENT this is what I'd like to focus on in a solution.

Your dismissive attitude isn't solving anything. You did not provide a solution, or verify that your work-around actually works.

If you used the process I sent you in the video, you will get the DXF that is attached to this message.  I am not defensive, you just are not trying on your end to help solve the issue by using the process outline.

I have followed your process and it DOES NOT WORK. 

How can you not accept that? If it does, kick me back a .DXF with my attached files that's not broken.

The file was attached to my last message.  It opens in tack in Fusion 360 and shows solid bend lines.  What else do you need?

@jhackney1972 - this post has been edited due to Community Rules & Etiquette violation.

 

What part of IT DOES NOT WORK is not being clearly communicated here? SCS does NOT recognize the bend lines with your process or files, and converting the projected DXF back into a 3D model to attempt to recreate a new flat pattern results in the same broken DXF files I began with.

I'll put it this way, either export a DXF that works appropriately and prove the point that this process works flawlessly, or accept that you gave bad advice and maybe work on your hubris here, "Expert Elite." Suggesting that I'm 'not trying on your end to help solve the issue by using the process outline' while bringing back feedback based on the given process is wild. 

Otherwise, I'm open to suggestions from Autodesk staff or others with experience on the issue.

As an addendum, exporting this bracket in STEP, bringing it into Solidworks, and converting to sheet metal allows me to flatten and export a functional .DXF file. 

So, seems to be a problem with Fusion.

This is a bug with Fusion360, it'd be nice if the product we pay for had help from Autodesk.

Are you a commercial user or using the personal licence? If you have a commercial licence then I'd suggest creating a support case through your account. What you're seeing is a very old bug where elliptical arcs are output incorrectly. I have reported these problems several times over the last few years!

 

What you can do is recreate your part using arcs and it will work fine. The difference between the arcs and elliptical edge are very small.

I've attached your file where I projected the faces edges from the original bracket into a sketch but used an arc rather than project the elliptical edge. See attached file.

I've opened the DXF in Fusion and Rhino and it looks correct.

@phillipJSCHJ From reading your posts I think you have a commercial licence so a better option is to create a 2d drawing then export as a DXF.

 

This is the drawing workspace with a 1:1 scale and tile and border hidden.

And here imported into Rhino next to your original DXF.

Thank you for the second look and the bug identification. This fix produced a functional .DXF.

It doesn't give me warm fuzzies that Autodesk hasn't solved this bug after several years, however.
