CAD Introduction

What is CAD?

CAD• Computer Aided Design

• Use computers to assist the design process

• CAD Software aids a designer to create models in an imaginary space

• Visualise all properties of the design

• Enables the conversion from a computer model to a manufactured piece

Ivan Sutherland created SketchPAD

Patrick Hanratty created ADAM

Automotive and aerospace companies started

developing their own software

Autodesk launched AutoCAD

Robert McNeel & Associates released

developed

How old is 3D printing?

Did you know?

Purpose of CAD

• Quality of the jewellery designs

• Increase productivity of designer

• Facilitates better communication and understanding

Efficiency

• Enables clients to get bespoke designs

• Enables easier modifications according to client’s needs

Customisation

• Being able to offer bespoke and exclusive designs provides a competitive edge

• Improve sales conversions

Competitive advantage

• Purpose of CAD is not to replace goldsmiths

• Create higher quality and innovative jewellery products by combining the best skills with technology

Collaboration

Pros and cons

CADvantages• Easier to visualise concepts

• Problem-solving is simpler on computer than on paper

• Trouble shooting can be done a lot faster

• Able to create complex designs and patterns at a fraction of the time to do it by hand

CADvantages• Depending on the software, CAD

models can be easily adjusted and modified

• Create your own cloud library of all your designs and be kept safe forever

• There are specialised software available for specific desired products

CADvantages• Once-off, bespoke or complex

design are possible

• In combination with 3D printer, high volume quantities of the same design is possible

• In combination with rendering software, creating your own virtual library of photorealistic images are possible

CADvantages• Reduced time to design

high quality, bespoke items

• Able to offer better prices to clients

• Provide accurate quotes in less time

CADvantages• Software relies on mathematical

and geometrical accuracy

• You are in control of all the dimension inputs

• Curves and patterns are created with symmetrical axis

• Get as close as possible to perfection

CADastrophes• CAD does not ensure quality; the

quality is dependent on other factors

• CAD saves time in bespoke design, quoting etc; however the CAM process is long and requires a certain amount of overheads

• Most software have a long learning curve

CADastrophes• To perform optimally, CAD software

requires powerful and expensive hardware

• Software licenses can be expensive

3D CAD

Introduction

Purposes• To view a design from all

different angles

• Create a preview to visually make decisions about colour or materials

• Exceptional levels of precision and accuracy in terms of measurements and dimensions

Purposes• Can be used as just a design tool for

presentations to clients in the form of renderings

• Can be used as design and manufacturing tool when combined with a 3D printer

• Cost-effective tool for bulk orders

Software options

Rhinoceros 3D

• Aka: “Rhino” or “Rhino 3D”

• Industries: Architecture, industrial, marine and jewellery design

• Free form surface modelling software

• Accurate and complex models

• Available for Windows and MAC

• Easy learning curve

• Affordable

• Easy curve manipulation for complex shapes

• Create 2D drawings

• Technical illustration

• Can be used for 3D printing

Pros Cons• Non-parametric

modelling

• Making modifications can be time-consuming

Software options

MatrixGold

• Successor to Matrix and RhinoGold

• Specifically created for jewellery

• Special tools for repetitive tasks like prong settings and pave

• Interface created by jewellers

• Same pros as Rhino

• Advanced jewellery tools for complex models

• Realistic rendering & animation

• Advanced 3D technology for accurate weights of metal

• Parametric modelling

Pros Cons• Complex tools

requires more experience

• Longer learning curve

Software options

3Design

• Specifically created for jewellery

• Parametric system

• Precise tools

• Powerful tools for micro-pave

• Realistic rendering

• Custom and complex shapes are easy with sweeping wizard

• Interface is intuitive and moderately easy learning curve

• Parametric system allows for easy modifications

• Organic modelling is easy

Pros Cons• Due to parametric

abilities, you need a high spec computer

• Software and add-ons are expensive

Software options

• Zbrush

• Carveco

• Geomagic Sculpt

• Mudbox
