2D shapes

rectangle()

Creates a rectangular closed wire from specified parameters.

Syntax

cadlib.rectangle(width, depth, center, dir);

Parameters

Name Type Description
width Number Width of the rectangle
depth Number Depth of the rectangle
center Point Center of mass
dir Vec3 Direction of the normal to the wire

Returns

Wire

Example


function build() {

    
    let width = 20, depth=20;

    //At origin
    let center = {x:0, y:0, z:0}; 

    //set wire orientation  along X-Z plane
    let dir = {x:0, y:0, z:0}; 

    //Create wire
    let w = cadlib.rectangle(width,depth, center, dir);

    //Create a face from the wire
    let f = cadlib.face([w]);

    //Extrude the face along +ve Y axis by 10
    let extrudeDirection = {x:0, y:1, z:0};

    let extrudeLength = 10;
    let solid = cadlib.extrude(f, extrudeDirection, extrudeLength);

    return solid;

    //TODO -  experiment with dir and extrudeDirection to understand how a rectangluar box will be oriented after extrusion.
