Fusion "Unmodified" Mesh Section Sketch exported to DFX will not insert or open in new Fusion doc.

Forgive me there is a solution elsewhere.  I didn't find one pertaining to this specific DFX insertion issue when searching.

Perhaps this is default behavior for an unmodified Mesh Section Sketch (one that hasn't had curves fitted), but I have a rather large and unwieldy mesh file (STL) reconstructed from a CT scan that I've sectioned many times (in the primary save file) for some practice reverse engineering.

Since it's terribly slow on this large save file I thought I'd export each Mesh Section sketch to DFX (or the ones I needed) then re-import them in a new doc on new planes created to represent the same locations/distances the sections were originally taken from.

Then and only then would I have the computer bandwidth to use the "Fit Curves to Mesh Section" dialog, and I could get on with re-creating the parts of the object I want.   

The problem is nothing happens when I select my DFX file(s) exported from the original Fusion360 project, from either insert, or open in a new document.  When I just  open a file I get a new tab with my DFX's name, but no lines or sketch.   When I go to insert on a plane in a new untitled document, I can select my 2KB DFX file, but the "OK" dialog stays grey, and it's not clear if the DFX was actually selected or not (from my computer), so again, I can't get to my mesh-section sketch.

I'm *guessing* this may be because you can't export orange mesh construction lines as a DFX (or they don't record as anything in a file)?  And you must create your fit-to-curves real lines first (which is a problem for me in this case)....  but I was just hoping to confirm, or find a fix, or suggest that a fix be implemented.

Thanks,

Did you convert the mesh section to curves first? A mesh section is not a set of curves you can export, its just a reference for conversion.

Thanks for the reply.  I'm *experimenting* and I'm new to this workflow.   I had hoped to take the resulting mesh section sketch and export that to a DFX to re-open in a smaller memory footprint and THEN generate fitted curves.  I thought this *might* end up being default behavior though.

The operations are just really slow on this file which balloons to a 25-28mb memory footprint (per PSEXEC) .  Yes I should have more memory, and maybe I over sectioned it.  It's a rather largish CT scanned object nearly a meter in length (A V12 race head).   Occasionally I have to kill Fusion with PSEXEC after a few hours of memory ballooning and it gets stuck.  Thankfully I'm jut playing around with it because either this old top end I7 isn't good enough to handle this file, or it wouldn't' be worth doing it this way.
