CAD design (computer aided design) is the use of software to produce an accurate, dimensioned drawing or 3D model of a piece before it is made. In custom fabrication, it lets you see and approve the design, and lets the maker catch problems, before any material is cut.
At a glance
- CAD stands for computer aided design: software used to draw a piece to exact dimensions before it is made.
- A CAD drawing shows the piece from several angles with its key dimensions marked, and complex pieces can also have a 3D view.
- Changes cost least at the design stage, before any metal, wood, cane or glass is cut.
- Fixed dimensions let materials be quantified properly, so the quote is based on the drawing rather than an estimate.
- At Accents & Art, you see and approve the design before fabrication starts in our Accra workshop.
What is CAD design?
CAD design is the process of creating an accurate drawing or three dimensional model of a piece on a computer before any material is cut, welded or shaped.
Dimensions, proportions and details are worked out on screen, where they can be checked, adjusted and refined. The result is one shared, accurate reference that you and your maker both agree on before anything physical begins. At Accents & Art, our CAD design and prototyping service produces that reference before any fabrication starts.
2D drawing or 3D model: which will you get?
The format depends on how complex the piece is: a 2D drawing suits simpler pieces, and a 3D model suits pieces whose form is hard to judge from a flat plan.
| Format | What it shows | Best for |
|---|---|---|
| 2D drawing | The piece from several angles, with key dimensions marked on the drawing | Simpler pieces where size and proportion are the main questions |
| 3D model | How the piece looks from any angle, how it sits in a space and how it catches the light | Complex commissions where a flat plan is not enough to judge the result |
What should you check on a CAD drawing?
Check two things first: whether the scale suits your space, and whether the level of detail matches what you pictured.
- Scale: does the piece feel right against a doorway, a wall or the furniture already in the room?
- Detail: does the drawing show the level of detail you described when you first explained the idea?
- Joints and seams: how will each joint look, and where will the seams fall?
- Material junctions: how does one material meet another?
Resolving these on the drawing means none of them has to be decided under pressure on a half finished piece.
Why does the design stage matter before anything is made?
A problem with proportion, scale or detail is far easier and cheaper to fix on screen than after material has been cut.
Timing is the main value of CAD. Once dimensions and materials are fixed in a drawing, the project can be costed properly, and what you agreed at the design stage is what gets made. That means fewer surprises later in the process.
What are the benefits of CAD for a custom piece?
CAD gives you four practical benefits beyond the drawing itself.
| Benefit | What it means for you |
|---|---|
| Problems found early | Visual and structural issues are resolved before fabrication, not during it |
| Accurate materials | Quantities come from the drawing, so there is less delay from ordering too little and less waste from ordering too much |
| A more accurate quote | The price is based on fixed dimensions rather than an estimate |
| A lasting record | A matching piece, an addition or a repair can start from the original drawing rather than from measurements taken after the fact |
How does CAD fit into making a custom piece?
CAD is the first working stage of a commission, and the approved drawing guides every stage after it.
- Concept: we understand what you are picturing for your space.
- CAD design: the drawing or model is prepared, and you review and approve it.
- Fabrication: our welding and fabrication team cuts, joins and welds the piece to the approved drawing, including CNC bending and forming where sheet metal is involved.
- Finishing: the surface finish is applied, usually by powder coating or spray painting.
- Installation: the finished piece is fitted in place.
Skipping or rushing the design stage removes the one step that keeps the rest of the process aligned with what you asked for.
How Accents & Art handles the design stage
At Accents & Art, every commission runs from concept and CAD design through fabrication, finishing and installation, all handled in our workshop in Accra, Ghana.
Before fabrication begins on your piece, we show you the design for approval, as a drawing, a model or both. This is your opportunity to ask questions, request changes and check that the scale and proportion suit your space, while an adjustment still costs nothing more than a conversation.
Frequently asked questions
How closely will the finished piece match the CAD drawing?
Very closely. The CAD model is built to the same dimensions the finished piece is made to, and any change agreed at the design stage is carried directly into fabrication.
Can I ask for changes after I see the drawing?
Yes. The design stage is the easiest and least costly point to change anything, because no material has been cut. Raising a concern at this stage is exactly what it is for.
Do I need a CAD drawing for a simple piece?
A simple piece still benefits from a dimensioned drawing, because it confirms size and proportion against your space before anything is made. For a simpler piece this is normally a 2D drawing rather than a full 3D model.
What should I check when I am shown a design?
Check that the scale suits your space, for example against a doorway, a wall or existing furniture, and that the level of detail matches what you pictured. Then look at how joints, seams and material junctions are shown.
Does a CAD drawing help with repairs or matching pieces later?
Yes. The original drawing is a lasting record, so a repair, an addition or a second matching piece can be made from accurate dimensions rather than from measurements taken after the fact.
If you are planning a custom piece, our workshop team can walk you through what the design stage involves. When you are ready, start a commission.
