2D software uses images called bitmaps.
These consist of blocks of color stacked together to make a picture.
Each image can be “in-scale” with the others, making them easy to size for basic design & layout.
The images can be very lifelike, but only show one view at a time, usually a top view.
The versatility of 2D allows images to be taken from anywhere.
Printed catalog items, existing items, or inventory lists can all be captured easily. Having this starting image makes the task of modifying it much easier.
A limitation of 2D is that only 1 angle at a time can be captured and altered, similar to a pencil sketch.
Why should we study computer aided designing, instead of manual designing?
Manual Designing, was the only form of jewellery designing until the introduction of Computer Aided designing (CAD).
With the introduction of Computer Aided Designing (CAD), jewellery which was drawn – designed on the paper (canvas), identical drawing could be made on the computer with much higher complexity and accuracy compared to manual designing.
Time:
Given a “X” period of time, a designer can make 5-10 designs on the computer compared to a design made manually.
If a designer makes 1 design using permutation and combination that one design on the computer can lead for 5-10 drawings which would not be possible if the jewellery is drawn manually.
Colour & drawing:
On the computer you are exposed to 13 million colours, you do not need to be good at drawing or an artist do draw on the computer as the tools available for drawing make it much simplier.
