When you click import a window pops up to select the dxf. In that window click into options at the bottom and try to uncheck “preserve drawing origin” if you can do that.
Try to import the file again.
It could be that the dxf requires some fixing to get it to a “decent” state though.
I tried various things, including using Illustrator and an online DXF viewer. Nothing showed in each case. I can open it in a text editor, and there are 654 lines of text. Exporting a rectangle from SketchUp give 124448 lines of text.
Not sure what’s going on. Will keep at it or just trace in Inkscape to make less complicated and bring over to Sketchup. Not sure why it’s not showing. Thanks!
I tried again, only I purged unused. The rectangle exported as 5030 lines of text. Lot better than the 124448 lines, but still over 6 times larger than your example file.
A scanned image does not convert automatically to vector lines by this method. Your DXF file only carries settings and such, but it contains no drawing entities.
