Hi,
I want to play with CNC and don't yet have any experience with CAD software (nor the licence for the expensive ones) other than perhaps some Blender, so I decided to try to use the super ugly route with metapost -> svg -> dxf -> g-code for the first time.
I have a few questions.
(1) I love Hans' shortcuts in metafun, but I seem to remember that things like input metafun; or perhaps input mp-tool; used to work, so that I don't have to remember to use mpost -mem=metafun my-drawings.mp when compiling the graphics.
Did the method with "input" ever work (or is it supposed to work)? Now I'm getting a bunch of weird errors. I would love to specify everything in the source file and then just call mpost. If that doesn't work, that's fine, I can still add "-mem=metafun", but ...
input metafun.mpiv ;
(2) I guess that using "raw metapost" is the only sane way to generate SVG. If I use metapost inside ConTeXt that's probably not going to work, right?
(3) Is there any way to convince the SVG output mode to generate something like
why not just \startMPpage whatever you want \stopMPpage and then use mudraw (mutools) to go from pdf to svg (that's what i do when i need svg)
(4) Does anyone have a better proposal for conversion into DXF (or G-code)? I'm currently playing with FreeCAD and I've seen some tutorials showing that AutoCAD can open PDF directly, but I don't want to buy AudoCAD just for the sake of converting files.
(Not to mention that FreeCAD's SVG importer crashes when reading output from MetaPost unless I manually remove parts of the SVG, but that's an unrelated problem that I'm somehow able to overcome.)
