Good morning, 
I'm trying to refresh my SolidWorks knowledge and I'm running into an issue while uploading a .DXF.
The drawing is one complete drawing/file in Lightburn and Inkscape. When I export from those and then open in SW, the whole line drawing is shown with nodes. When I select everything, then rotate my view, some of my lines and connections are disappearing. They reappear when I'm done moving, but the outline still isn't filling in like a closed object. I've tried the repair tool, and it says there's nothing to repair.
