![]() 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. Right, the geometry is not properly preserved on STL the way it is implemented in OpenSCAD, it is destined to fail for such cases. the result is very thin slivers and OpenScad seems to not be able to. 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: When imported the results are differenced with the non-trucated versions. ![]() 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. Main window of OpenSCAD shows a rendering model. If I tried exporting a PDF or SVG of the model (File > Export > Export as PDF.), it understandably didn't know what to do: stl file format is free OpenSCAD (Solid 3D CAD Modeller), it can be downloaded. 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). Render with 'F6' on each step step1 if(step1) planes() // export as 'step1. Like it or not, STL is not suited for such purposes. 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. This illustrates that STL files as implemented today also fail to preserve geometry 100, leading to errors when trying to import and perform boolean operations. ![]() 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!
