CAD can be used to create structures, mechanical parts, and molecules, among other things. A benefit of using CAD is that people don’t need to make prototypes demonstrate a project and its potential, as they can use a 3D modeling program to show people how something might look. CAD allows for endless variations and experiments to show how something can be varied, and these can be done only at the click of a button, rather than with laborious drafting work.
The users many times like to play with CAD for deciding how to organize their furniture, or lay out a garden. You can drag and drop elements and play with space in a variety of ways, and generate a configuration which will be suitable and very pleasing. CAD is used by people in a number of industries across the manufacturing sector, and it also appears in some multitude of places, like forensics labs, where researchers recreate crime scenes on a computer to investigate scenarios.
Advanced CAD programs require thorough training for their users, as they could be very complex and challenging to work with. More programs can be learned in shorter durations of time, with some designed to allow people to work within the program immediately while learning.
Simple programs might also sometimes have their working increased with expansion packs which are designed to provide additional features, such that professionals can work within a program they are familiar with when they want to develop more complex designs.
