📏 cad3d - 3D CAD Modeling

🚀 Quick Start

import cad3d

// CSG (Constructive Solid Geometry)
let box = cad3d.box([0.0, 0.0, 0.0], [2.0, 2.0, 2.0])
let sphere = cad3d.sphere([1.0, 1.0, 1.0], 1.5)

// Boolean operations
let union = cad3d.union(box, sphere)
let intersection = cad3d.intersection(box, sphere)
let difference = cad3d.difference(box, sphere)

// Extrude (2D profile -> 3D solid)
let profile = cad3d.circle(1.0, 32)
let cylinder = cad3d.extrude(profile, 5.0)

// Revolve (rotate profile around axis)
let vase = cad3d.revolve(profile, [0.0, 1.0, 0.0], 360.0)

// Export
cad3d.export_step(union, "part.step")

📚 CAD Operations

• Primitives: box, sphere, cylinder, cone, torus
• Boolean: union, intersection, difference
• Transforms: translate, rotate, scale, mirror
• Modeling: extrude, revolve, loft, sweep
• Export: STEP, IGES, STL

💡 Exampleler

import cad3d, math

function bolt_create(uzunluk: float, çap: float) -> Solid do
    // Shaft
    let shaft = cad3d.cylinder([0.0, 0.0, 0.0], çap/2.0, uzunluk)
    
    // Head (hexagon)
    let head_profile = []
    each i in aralık(0, 6) for do
        let angle = i.float() * math.PI / 3.0
        let x = math.cos(angle) * çap
        let y = math.sin(angle) * çap
        head_profile.ekle([x, y])
    end
    
    let head = cad3d.extrude(head_profile, çap * 0.7)
    cad3d.translate(head, [0.0, 0.0, uzunluk])
    
    // Thread (simplified)
    let thread_depth = çap * 0.1
    let helix = cad3d.helix([0.0, 0.0, 0.0], çap/2.0 - thread_depth, uzunluk, 2.0)
    
    // Combine
    let bolt = cad3d.union(shaft, head)
    bolt = cad3d.difference(bolt, helix)
    
    return bolt
end

let m8_bolt = bolt_create(50.0, 8.0)
cad3d.export_step(m8_bolt, "m8_bolt.step")

import cad3d, math

function gear_create(teeth: tamsayı, module: float, thickness: float) -> Solid do
    let pitch_radius = module * teeth.float() / 2.0
    let base_circle = cad3d.circle(pitch_radius, teeth * 4)
    
    // Tooth profile (involute curve - simplified)
    let tooth_angle = 2.0 * math.PI / teeth.float()
    
    let gear_profile = []
    each i in aralık(0, teeth) for do
        let angle = i.float() * tooth_angle
        
        // Tooth tip
        let tip_r = pitch_radius * 1.1
        let tip_x = math.cos(angle) * tip_r
        let tip_y = math.sin(angle) * tip_r
        
        gear_profile.ekle([tip_x, tip_y])
        
        // Tooth root
        let root_angle = angle + tooth_angle * 0.5
        let root_r = pitch_radius * 0.9
        let root_x = math.cos(root_angle) * root_r
        let root_y = math.sin(root_angle) * root_r
        
        gear_profile.ekle([root_x, root_y])
    end
    
    let gear = cad3d.extrude(gear_profile, thickness)
    
    // Center hole
    let hole = cad3d.cylinder([0.0, 0.0, 0.0], pitch_radius * 0.3, thickness)
    gear = cad3d.difference(gear, hole)
    
    return gear
end

let gear = gear_create(24, 2.0, 10.0)
cad3d.export_step(gear, "gear.step")
