This SVG was created by the LightBurn app. This is the program I use to drive my laser cutter/engraver. The workflow that I need starts with a collection of existing DXF files. Lightburn ingests these fine and I use them to cut work, in this case a small gift box from heavy paper stock. I need to get this vector data into AD, where it is the basis for creating artwork that is printed on the paper stock before scoring and cutting on the laser. AD does not import DXF, but LIghtBurn exports SVG, which AD is supposed to be able to ingest, so I was hopeful this approach would work. Some of the SVG files created in this way do open in AD OK after being exported from LightBurn. I can deal with scaling and viewport issues (like in the AI example above and I see when AD exports SVG) but when a vector path segment is randomly misplaced like in the example, and all the other apps I have tried interpret the file correctly, it seems like something basic is broken in AD SVG. I don't know if it is related the the issue that polynaught points to, but it is a bit scary if it is and years later the problem persists.
