I’ve run into a very strange error and I’m hoping someone can point me in the right direction.
I operate a static cutting table which means that I receive 2D geometry in Rhino which I then run through a nesting software and then import to the table’s cutting software. Our nesting and cutting software both are able to export/read dxf file types so that is what we use.
This system has worked for years- but recently we updated Rhino and I’m getting a replicable error.
If I export a dxf file from our nesting software and import it straight to our cutting software, then it works.
If I create a dxf file in rhino and import it to our cutting software (Without running it through the nesting software) it works.
But if I run a dxf file through our nesting software then open it up in Rhino to make any adjustments (Adding, deleting or moving curves. Nothing to do with any layers or settings.) and resave it as a dxf I will then be able to open it in our cutting software but with the strangest error.
The file will open, but most of the curved lines will have been broken into several small segments and some of those segments will then be flipped so that they are mirrored and outside the original footprint of the geometry.
It’s hard to describe, but these are some screenshots; first of the file as it appears in Rhino and then as it appears in our cutting software.
And this is the export settings for our nesting software.
I’m at a loss to think of what could explain this and so far haven’t been able to find a solution. I would think that it shouldn’t make a difference- I’m saving the adjusted rhino file as a dxf as I always have.
Up until a few months back I have done this exact thing several times without issue. And those files that I created using this method from before the Rhino update will still open in our cutting software.
The only changed variable seems to be rhino.
Any ideas on what could be causing this or adjustments I could be making to prevent this? Thank you!
