If they are used, $fa, $fs and $fn must be named parameters. Values of 3 or more override $fa and $fs. $fn : fixed number of fragments in 360 degrees. $fs : minimum circumferential length of each fragment. $fa : minimum angle (in degrees) of each fragment. scale() circle(200) // create a high resolution circle with a radius of 2.ĭ : circle diameter (only available in versions later than 2014.03). Note: These examples exceed the resolution of a 3d printer as well as of the display screen. For a small, high resolution circle you can make a large circle, then scale it down, or you could set $fn or other special variables. r name is the only one optional with circle.Ĭircle resolution is based on size, using $fa or $fs.

Parameters: size single value, square with both sides this length 2 value array, rectangle with dimensions x and y center false (default), 1st (positive) quadrant, one corner at (0,0) true, square is centered at (0,0) default values: square() yields: square(size =, center = false) Ĭreates a circle at the origin. Argument names are optional if given in the order shown here. When center is true the square is centered on the origin. Note: The try to substract with difference() from 3D object will lead to unexpected results in final rendering.Ĭreates a square or rectangle in the first quadrant.

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.

SPIRAL IN OPENSCAD HOW TO

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. 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.
