When I export an SVG file from EasyEDA, with all layers set to black, some viewers display the file correctly. However if I open the file in Visio, it appears as a blank screen until I highlight the entire area and set the line color to black, when it appears as expected. If I import the EasyEDA file into Glowforge laser software, it appears blank, and says there's nothing to cut.
If I save the file from Visio after changing the lines to black and import it into Glowforge, it appears as it should.
I looked at the EasyEDA file and messed around with the STROKE command, but couldn't find any combo that made the file appear as it should in Visio, and therefore work in Glowforge without extra steps.
I'm hoping to find what needs to be edited in the EasyEDA file to solve this problem. Attached is an EasyEDA SVG file of a 100mm x 100mm open square - change the extension to svg. If anybody is knowledgeable in this subject, I'd appreciate your advice.
