to According to the SVG standards at: the datatype "length" used in the length and width descriptors of an SVG file can be just a number, or a number plus a unit (10, 10mm, 10cm, 10in, etc.) Could it be an option to set the units of an SVG file so that we don't need to edit the file first? I personally would have no problem if the default SVG units for the width and height were set to mm, since that is the defacto standard for 3D models, it would make sense to be that way for 2D models as well. Im not so sure about the not-rewriting part, as some code is necessary to accomplish your objective. SVG file itself by changing this line in the file thusly: This means that anything I try to cut from OpenSCAD is much smaller than it needs to be. In Inkscape, which I use for my vector editing, Inkscape defaults to px as the default unit if no unit is given. STL (ASCII only) OFF AMF Note: Requires version 2015.03 3MF Note: Requires version 2019.05. When OpenSCAD makes a SVG file, it does not put any units in for the dimensions. An STL file (also unitless) that I make in OpenSCAD with "cube(10)" pulls up on every single slicing program I have tried as a 10mm cube. OpenSCAD is unitless, but de facto standard is that the units are in millimeters. This reduces a lot of whiplash on the laser or cutting head. If doing multiple passes, the cutter does each line segment n times, then moves onto the next segment. DXF files import a circle as a group of lines, each of which is cut by the laser. It works much better than DXF export for things like a laser cutter. Firstly, thanks for implementing SVG export.
