Although OpenSCAD has been designed for 3D modeling, you can also use it to create some flat 2D models, which can be exported as DXF files (Id prefer an SVG export, but thats another issue). If this happens, select Design | Flush Caches and then Design | Reload and Compile. 2D laser cutting and CNC is not hyped as much as 3D printing, but it has similar potential. OpenSCAD doesn't always provide information about the issues it encountered with a DXF import. Although EXDXF provides you with numerous options when exporting to DXF the most important option for OpenSCAD compliance is to set Line Conversion to Line and Arc. there is constructive solid geometry (aka CSG) and second there is extrusion of 2D outlines. Since pstoedit does not natively support Adobe Illustrator files, one alternative is to use EXDXF, which is an Adobe Illustrator plug-in (30 free trial exports and then you have to pay $90 to register the plugin).īefore exporting, it is recommended that you ensure that your Artboard is the same dimensions as the component you are exporting. OpenSCAD is a software for creating solid 3D CAD models. Ln -s /path/to/this/svg_to_dxf_makefile makefileĪI (Adobe Illustrator) Īlthough Adobe Illustrator CC/CC.2014 allows you to export illustrations as DXF (and select DXF format versions as early as 12), it uses DXF entities that are not supported by OpenSCAD, such as POLYLINE and SPLINE. The conversion can be automated using the make system put the following lines in your Makefile: Pstoedit -dt -f dxf:-polyaslines\ -mm intermediate.eps outfile.dxf Then pstoedit can convert the EPS to DXF. Pstoedit -dt -f "dxf: -polyaslines -mm" infile.eps outfile.dxf (If the rendered text's resolution in terms of polygon count is too low, the easiest solution is to scale up the eps before converting if you know a more elegant solution, please add it to the example.) The -dt options instructs pstoedit to render texts, which is usually what you want if you include text. The -mm option sets one mm to be one unit in the dxf include this if you use one unit in OpenSCAD as equal to one millimeter. OpenSCAD needs the -polyaslines option passed to the dxf output plugin to understand the file. The pstoedit program can convert between various vector graphics formats. ![]() Other common formats are PS/ EPS, SVG and AI. Look forward to your updates and youtube posts.Currently, OpenSCAD supports DXF only as a graphics format for 2D graphics. Of course, it does also come with compute hardware requirements so i understand why it may not work for some. for example bending of materials which i've found useful for a metal project of mine and may have been useful in your case too. switching to direct design is useful for quick tweaks (though the geek in me eventually wants to get around to turning those back into parametric design elements!) and of course comes with a lot of other neat functionality. ![]() i've found that adjusting the dimensions in the underlying sketches that support the models serves the functionality that i sought in OpenSCAD. so stuck it out with Fusion 360 and have to say that there's value in once you get over the initial learning curve. Wanting a parametric design tool, i also tried to get into OpenSCAD but ultimately decided that i didn't have time or brain-space for yet-another programming language. ![]() Now I'm thinking of how much easier many of my Illustrator drawings would be if I just programmed them in OpenSCAD. My DDG searches weren't quite coming up with anything besides a few old GitHub issues. I decided to put up this blog post in the hopes it might help someone else doing the same thing. Now it shows up as a 2D plane drawing:Īnd now the 'Export as PDF.' option (as well as the other 2D options like SVG) works great, allowing me to save a to-scale PDF suitable for reference or printing: To get something exportable, I just added projection() at the top of my model to turn the top-down view into a 2D projection, then Rendered the object. If I tried exporting a PDF or SVG of the model (File > Export > Export as PDF.), it understandably didn't know what to do: Some online utilities took an STL file and turned it into a PNG, but they weren't great and most wouldn't output a PNG with the exact dimensions as the model (they printed too big or too small). The idea was to print a to-scale line drawing of the part on my laser printer, cut it out, fold it, and check to make sure everything lined up correctly. Before 3D printing the final design, or cutting metal, I wanted to 'dry fit' my design to make sure my measurements were correct. One thing I wanted to do recently was model a sheet-metal object that would be cut from a flat piece of sheet metal, then folded into its final form using a brake. I've been getting into OpenSCAD lately-I'd rather wrestle with a text-based 3D modeling application for more dimensional models than fight with lockups of Fusion 360!
