CAD

CAD software can reduce the amount of work required from a designer. Some of the biggest advantages are that; changes to designs can be made more easily than with manual graphics; accuracy can be far greater than manual graphics; drawings can easily be emailed to team members or clients anywhere in the world; models can be rapid prototyped for testing or presentation. Garden design software is used as an example in the link below. []
