Building Plan

The building plan is defined by a parameter list that follows the workbench's identifier. All parameters in that list will automatically become properties of the workbench when it is invoked. These properties can be accessed within the building code, inside functions, or externally.

The following code demonstrates this using a sketch with a single parameter in the building plan, called radius, of type Length:

// sketch with a radius as building plan
sketch Wheel(radius: Length, thickness = 5mm) {
    use std::geo2d::Circle;

    // access property radius from the building plan
    Circle(radius = radius + thickness) - Circle(radius)
}

// access property radius of a Wheel
w = Wheel(1cm);
// render Wheel
w;

// check if r is 5cm an thickness equals the default (1cm)
std::debug::assert_eq([w.radius, 1cm]);
std::debug::assert_eq([w.thickness, 5mm]);
