I would like to do some simplification of the geometry,Ĭombining adjacent triangles with the same normal into a single polygon,īut am currently doing that manually. On the Z centre of the bounding box, and displayed from back to front. FacesĪre shaded based on the X and Y components of the normal, sorted based Have a normal that has a negative Z component (i.e. a snapshot of the 'top' view), culling any faces that It uses the X and Y coordinates of the triangles to draw a 2D image asĪn SVG file (i.e. I wrote my own Perl script to do a basic conversion of a triangle Out if there was any STL to SVG converter, with no luck. As a result, I spent a bit of time hunting around to find Issues with holes in the image, and a file size that was far too big for SVG conversion (traced using Inkscape) without much success. Here is the modified code: Path_to_STL_File='/home/none3/Desktop/.Over the weekend I tried to use OpenSCAD to generate a good PNG file for This is handy for when you don't want to build a new model completely from scratch and you already have a design that has parts that are the right size and have cut outs in the right place, or if you have the STL file but lost the original SVG files.Īdditionally you can modify the code to slice either an svg file or an stl file from what you have selected by checking a check box: right click and open image in new tab for a larger view

Then I can select everything and break apart the path to use the different parts, or modify them to use in another design. Here is the code: Path_to_STL_File='/home/none3/Desktop/.stl' Īfter clicking render I can save the selection as an SVG file that I can modify in Inkscape: right click and open in new tab for a larger image

Openscad has an option to make a projection that you can save as an image, so I made a way to automate the process with the ability to see what the section you are are slicing looks like compared to the model:Īs you can see above there is a slider that allows you to move the projection (shown in red) and a visual representation of the model, then save the section you want to a file.

Once in while I want to design a new case for a controller and need to make modifications to an existing design, here is an easy way to take some snips from a design you already made and modify them to use in another deign.
