Issue with Open Vectors in Onshape → OpenBuilds CAM

Hi,
I designed a bracket in Onshape and exported it as a DXF file for use in OpenBuilds CAM. When I try to generate a toolpath, I get the following error message:
"This toolpath contains 1 open vector(s), and 0 closed vector(s). You cannot use Offset operations on Open Vectors. You can try to use 'No Offset' operations or repair the file first."
I assume that some of the lines in the DXF file are not properly closed, but I’m not sure how to fix this in Onshape.
Questions:
- How can I check and close open vectors in Onshape before exporting?
- Are there specific export settings I should use to ensure the DXF file is correct?
I’d really appreciate any help!
Thanks in advance 😊

In an Onshape sketch, if that does import closed, then it should form a visible, clickable, highlightable face. if it doesn't import closed… won't it show no face? Does it do the same sort of thing in OpenBuilds CAM? (I'm not familiar with even the name of this software)
I think the way you would check open/closed would be by checking if a sketch face is visible. And if it's a 3d object maybe making a sketch on top and using the Offset tool to offset it all by 0 to make it a projection. (i think the Use tool does exactly this and only today i learnt of it's existence… oopies)
Anyways, what that should do is make that face a completely closed surface.
I don't usually export DXF but it looks like the standard version is "Release 14." Maybe that CAD program uses an older version
