OpenSCAD support¶

Parametrization¶

OpenSCAD file variables can be turned into parameters by adding a comment above it describing the parameter and optionnally another comment at the end of the line describing its type and range. For example:

// angle in degree
AX=90;

The following code defines a parameter “AX” described by “angle in degree” in the customization page, and with default value 90. Without other information, the parameter is presented as a text input. To use other types of input, another comment may be added at the end of the line.

// angle in degree
AX=90; // [45:90]

This code will present the parameter as a slider ranging from 45 to 90. Finally it is possible to present a list of choices like so:

// angle in degree
AX=90; // 30,45,60,90

or to name the available choices like so:

// angle in degree
AX=90; // 30:Thirteen,45:Fourty five,60:Sixty,90:Ninety

Example¶

A sphere minus two cylinders of customizable angle

Download

// angle X
AX=90;
// angle Y
AY=90; // [45:90]

module example001(anglex,angley)
{
    function r_from_dia(d) = d / 2;

    module rotcy(rot, r, h, angle) {
        rotate(angle, rot)
            cylinder(r = r, h = h, center = true);
    }

    difference() {
        sphere(r = r_from_dia(size));
        rotcy([0, 0, 0], cy_r, cy_h, 90);
        rotcy([1, 0, 0], cy_r, cy_h, anglex);
        rotcy([0, 1, 0], cy_r, cy_h, angley);
    }

    size = 50;
    hole = 25;

    cy_r = r_from_dia(hole);
    cy_h = r_from_dia(size * 3);
}
