Linear extrusion is similar to pushing Playdoh through a press with a die of a specific shape. OpenSCAD provides two commands to create 3D solids from a 2D shape: linearextrude () and rotateextrude (). To assist you in understanding how it works, I offer the following OpenSCAD script that demonstrates what happens if Spiral270.dxf is intersected with a circular ring. Extrusion is the process of creating an object with a fixed cross-sectional profile. It generates exactly the same STL with a single twisted extrusion, so it should be easier to figure out what's really happening. The extra subtraction removed a further 30 degrees to bring the total to 270 degrees (3/4 of a revolution).įor your benefit I incorporated your comments, simplified the script and DXF file, and uploaded new versions to Thingiverse as Rhombic270.scad and Spiral270.dxf. My original spiral.dxf had been created for making a trisection, so it was optimized for a script to subtract 240 degrees (2/3 of a revolution). kristina panos liked The Companion Light v1.0.The two helical subtractions aren't actually different, that's just an unnecessary distraction.sa liked Sinclair Scientific Calculator Emulator.100dollarhacker has updated the log for Atomic Force Microscope - from ground up.wglasford has updated the log for Apollo Saturn V and LUT.kristina panos liked RETRO 1 - Home Computer Console.A double-spiral will have equal and opposing twist forces at the center, and stretched all the.

You can watch the whole video below the break. This also leaves the possibility of using the same code in other PCB packages. The solution is to write a simple JSON interpreter in KiCAD, and leave the spiral generation to an external script that passes a JSON. Similar to the stack of shapes that a 3D printer slicer makes, and that actually gets printed.

Instead of drawing threads on a cylinder, it creates a stack of circle(ish) discs that represent a slice from a screw.

Having perfected the algorithm, how to bring it into KiCAD? The PCB CAD package has its own Python environment built-in, but it’s not the most flexible in which to develop. This screw library takes a different (simpler) approach to making threads.

Drawing a trapezoidal spiral is a surprisingly difficult task for a script, and we’re treated to a variety of algorithms in the path to achieving a usable design. But there is still much to be learned in the creation of the inductors themselves, and has recently been investigating their automatic creation through scripting.Ī simple spiral trace is easy enough to create, but when for example creating a circular array of coils for an electric motor there’s a need for more complex shapes. PCB inductors are a subject that has appeared here at Hackaday many times, perhaps most notably in the electromagnetic exploits of.
