A Computer Aided Design and Manufacture Software for Jewellery

JewelCAD is a 3D free-form surface based solid modeler. It provides powerful free-form modeling tools that allow freedom in creating artistic and stylish designs. These tools are flexible and intuitive and they can be easily learned and used. JewelCAD is now widely used in the jewelry manufacturers in Asia region.

JewelCAD 5.1Specifications

Design Geometries

Curve

- B-Spline curve : smooth curve defined by a few controlvertices (CV's)

- symmetric curve,curve with linear and circular repetitive patterns can be created interactivelyin JewelCAD

- curves bysketching and transformation by values in move, size, scale and rotate

- curveprimitives: line, circle, polygon and helix

- curvesoperation: close, open, reverse, divide, split, join, offset, in between, curvelength

Surface

- B-Spline surface : smooth surfacedefined by an array of control vertices (CV's)

- created byExtend, Revolve, Loft, Pipe and Rail functions

- transformationby values in move, size, scale and rotate

- surfaceprimitives: cone, sphere, cylinder

- surfaceoperations: close, open, reverse, divide, step size, swap UV, flip normal andoffset.

Jewel

- Built in jewelsof round, oval, marquise, pear, heart, square, rectangular, octagon, triangleand taper shapes

- Jewel natureassigned by users

Block

- 3D object created by extending 2Dplanar curves

-can have islands and holes

-can have sharp, filleted or chamfered edges

Text

- all true type fonts of Windowssystem can be made use for generating 3D text

Boolean Operations

- surfaces, blocksand jewels can be combined together by union, intersect and subtract Booleanoperations

- Supersubstractorfor automatic substraction of all objects except jewels mainly to facilitatehole drilling for setting.

Transformation and Deformation

Transformation

- Move, Size, Flip and Rolloperations with respect to world origin and object axis

Deformation

- Interactivedeformation operations include: Bend, Two side bend, Taper, Two side taper,Scaled taper, Two side scaled taper, Skew, Two side skew, Twist, Sk-twist andWhirl

- Transformationthrough values for Move, Size, Scale and Rotate

- User define fornon-deformable objects

- Parametric mapping onto curves andsurfaces

-Projection mapping onto curves and surfaces

Transforming and Deforming individual CV's

- Individual CV'sof curves and surfaces can be picked for transformation and deformationoperations

Copy

Copy with cursor

- objects copied freely at thecursor position

-objects copied onto a surface with control on position, size and orientation

Symmetric copying

- symmetriccopying functions include: Mirror, Cyclical, Linear repetitive and Circularrepetitive copying

- copy withtransformation in values for move, size, scale and rotate

Built-In Database

- library forparts, rings and settings; settings include shape in heart, marquise, oval,pear, square, taper and round

- user extendabledatabase

Rendering

Realistic rendering

- design renderedin true color picture to look real

Fast shading (Supporting OpenGL)

Outline drawing

- outline of design is drawn withhidden lines removed

Image File Format

- 24-bit true colour Windows BMPfiles

-resolution unlimited

-anti-aliasing

- different choiceof background

Rendering material

- Materiallibraries for metal and general colors

- User definematerials with control in colors (ambient, diffuse, specular), texture, bumpmapping, reflection mapping and shiny mapping, shinyness and transparency

Manufacturing

Rapid prototyping

- designs created with JewelCAD areready for rapid prototyping

-no tedious pre-processing (such as surface trimming) required

-JewelCAD automatically cuts designs into slices of contours

- slices ofcontours are output in 3D systems SLC format

- STL format inAscii or Binary from the conversion of SLC data

CNC machining

- JewelCAD canalso generate Fanuc GM codes for Computer Numeric Control machining

- Generate also NCcodes for Roland MDX-15/20 machine
