Instead lets use some web development skills and build a form using HTML. Command line is great for programmers but is scary for most people. Now we need to make things more user friendly. This process of setting variables in the model is the exact same approach that the configurator on this site will use.

If you wanted a gear with 100 teeth, running the following command line code on your computer would generate a STL file containing such a gear. Gear(circular_pitch=PITCH, gear_thickness=THICKNESS, number_of_teeth=TEETH, bore_diameter=BORE_DIAMETER, hub_diameter=BORE_DIAMETER+2) I am using the MCAD library to generate everything. It generates a 3D gear using four variables to control the pitch (density of teeth), number of teeth, thickness of the gear and size of the center bore hole. For example here is one with a few variables. The first thing you need is a SCAD model.

In this post I will be going through an example of how to build a configurator where anyone can customize the 3D models that you design. With this port, anyone can package and share OpenSCAD projects on the internet.

A WebAssembly port of OpenSCAD that can be run in any modern browser. So, I got to work and after a few months of hard effort I created this: DSchroer/openscad-wasm. Sites like Thingiverse looked like the solution but I was looking for something that I could put on my website, that would have zero cost, and where I could fully customize the user experience.

As a software developer, I find it the most intuitive and scalable way to build models. Instead open polygons are treated as shapes defined by their stroke-width.Ĭlosed shapes are always using the geometric specification regardless of fill or stroke-with defined in the SVG file.Build an OpenSCAD WASM Configurator - Dominick Schroer's Blog OpenSCAD handles only closed polygons, so importing lines or open polygons is not possible. The article Understanding SVG Coordinate Systems and Transformations gives a nice introduction of how all combinations of the viexBox related attributes affect the display.ĭPI handling Edit Open and closed shapes Edit The OpenSCAD import supports the tranformations including the preserveAspectRatio attribute. The ViewBox attribute of the SVG file defines the initial coordinate system for displaying its content. In general the OpenSCAD SVG import extracts the core geometric information of the objects and transforms that into closed 2D polygons. Especially all animation features and most visual properties in the SVG file are ignored. This means there are a number of features that do not translate well into the use as CAD format. Scalable Vector Graphics (SVG), as the name already implies, is designed to be a scalable graphics format targeting rendering on Web pages with support for interactivity and animation. The minimum segment length to use when converting circles and arcs to polygons. The minimum angle step to use when converting circles and arcs to polygons. The number of polygon segments to use when converting circles, arcs, and curves to polygons. If an absolute unit is given for width/height (px/pt/pc/in/mm/cm) the DPI value is ignored. for files created with older versions of Adobe Illustrator). If no width/height is given at all the viewbox is used instead (e.g. Use this DPI value for calculating the size of the viewbox if no unit is given for width/height.

If set to true, the imported geometry is centered by bounding box of the geometry. Import(file = 'file.svg', center = false, dpi = 96) OpenSCAD can import the geometric structure of SVG files.
