Extra Line Entities for Watercut

[davidSWEUU]

I have sent a DXF file to have water cut and I got the following response back from them:

"There are numerous unnecessary line entities that require removal with the supplied file. The above quote could be reduced if you have a real spline drawing you can provide...?"

I have opened the DXF and it looks very clean to me.  does anyone have an idea what they are referring to?

If you open the F3D it is under: "Modified>Option 1"

I have come across the same issue. If you create the DXF from your own sketch geometry its fine. However if you are projecting geometry to a plane, Fusion likes to add extra lines. If you go to your preferences;Design and turn off “Auto project edges on reference” and “auto project geometry on active sketch plane”  it eliminates the extra lines. Not 100% of the time, I’ve seen it sneak it a few extra on the actual DXF export file. 

Another problem I have ran into is the shop themselves. Sometimes their waterjet software hasn’t been updated in over a decade! If thats the case then random segments will not cut despite it showing on the screen as a cut path. Ive seen this more so with the Flow software. The Omax hasn't given any issues.
