Cad2Cam

A 3D WebGL CAD and CAM program working on most recent browser and specially on PDA and Tablets It must meet the following requirement :

• ❏ web based

• ❏ touch compatible

• ❏ easy to use

• ❏ from idea to 3D printing

• ❏ Offline ready

• ❏ versioned (github, bit bucket)

• …​

cad2cam's Issues

perform multi touch gesture on 2d draft

1 finger to draw
2 fingers to pan, rotate and pinch on the plane

navigate in history

Be able to go back and forth in the construction history

generate shapes based on sketch

https://github.com/mrdoob/three.js/blob/master/src/extras/geometries/TubeGeometry.js

deal with csg geometries

https://raw.githubusercontent.com/joostn/OpenJsCad/gh-pages/csg.js

define sketch plane

Transform a face to an sketch plane

add constraint between elements

It's possible to remove or to add constraint to elements or between elements
1 horizontal or vertical
2 tangent ,perpendicular, parallel or with a specific angular
3 length, symetric, coïncident
....

generate gcode

Generate gcode from 3d shape

find sketch lines and points

While drawing on sketch plane, the system should show you the most important sketch lines and points like middle of a segment, center of a polygon, perpendicular to a line or tangent to an arc

draw sketch in a canvas

The sketch should be drawn in a canvas or in SVG

drawing simples shapes

you should be able to sketch simple shapes for extrusion or rotation solid

analyse constraint

Change esquisse color based on constraint

• unconstrained
• just constraint
• hyper constrained
