I have a workflow whereby I use Lightburn to import a large (area) pdf. I then break the imported parts down to the specific ones I want and export (part by part) an svg of each part. I then move to my 3d cad program and import the svg into my modeling sketch. Once I have made the required mods to the part(s) I will take them back to Lightburn via dxf and cut them on my laser. Problem: The exported svg, imports as a very small figure, and the 3d cad cannot diagonally scale it back to the required full scale size. Even a simple square of 75mm from Lightburn, imports as a 1.984375mm square in my cad program. A square I can fix easily in my cad, but compound curves - not so.
I can successfully do this by exporting a dxf file from Lightburn and taking that into CorelDRAW, and then exporting an svg from CorelDRAW - but this is quite cumbersome.
My sense is that something is missing in the svg file export by Lightburn, while the dxf export works perfectly (but I have no facility to import dxf into my cad sketch process, only svg (: ).
75mm square test export.lbrn2 (2.9 KB)
Above are the two files for the 75 mm square: 2nd file is the square in my Lightburn space
and the first file is the resultant export of the svg.
I also tried it in Fusion 360 but that came in at 19.844mm:
So with most applications I tried it came in at the correct size. I had a look at the SVG in a text editor and some of the values are specified as mm and others have no units (I don’t know whether that’s the cause of the issue).
