For simple shapes I'd choose Inkscape SVG editor, which can export to DXF directly. In settings you can customize the coords precision to reduce those fractions. For more sophisticated designing I'd skip simple 2D CADs and use parametric tools instead (allowing to use equations instead of fixed values which simplifies future refactoring). I'd recommend Autodesk Fusion, which is even free for enthusiasts: https://knowledge.autodesk.com/support/fusion-360/troubleshooting/caas/sfdcarticles/sfdcarticles/How-to-activate-start-up-or-educational-licensing-for-Fusion-360.html https://www.youtube.com/watch?v=VzqXo0d0W8s Jan ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________
