Computer-aided design (CAD) software comes in different sizes, including 2D, 2.5D, and 3D. 2D is best for architectural plans, 2.5D adds a false Z-axis for more detailed designs, and 3D creates accurate models for products. Modeling CAD programs have more features and can show internal parts or moving objects.
Computer-aided design (CAD) software, also known as computer-aided design software, comes in many different packages so that operators can create plans on different floors and the software can leverage the user’s strengths . When it comes to choosing computer-aided design software, the most common difference between programs comes down to size. There are 2D, 2.5D, and 3D or three-dimensional computer-aided design software and special 3D CAD programs made for modeling objects such as solid or wireframe objects. All of these types of programs can be used to create successful building plans, so it’s up to the user to choose which program is best.
In 2D computer aided design software, there is only one X axis and one Y axis to draw on. There is no depth, making all designs look flat. Users must rely on simple geometric shapes to create plans. This is best for architectural plans, because these plans don’t need depth for the workers to create the house or building.
With 2.5D, no real depth is added to the planes, but a false Z-axis is introduced to trick the mind into thinking there is depth. This is similar to how a painter or drawer can show the depth of the object on a flat piece of paper or canvas. The objects made are prismatic in this computer aided design software. The objects are still simple geometric figures like those in 2D CAD, so this can be used for more detailed house plans and designs where a sense of depth is needed.
When using 3D computer aided design software, the user actually makes a 3D representation of the object. There is depth and the object has different sides that can be rotated and moved. This creates accurate models, but the user must be technically competent to make the object. These CAD programs are best for creating products, for which a flat drawing may not fully capture all of the necessary detail. Printing is sometimes a problem with 3D CAD, because the model cannot be moved onto paper and the user will have to print each side for a complete representation.
Modeling CAD programs are similar to 3D programs but have more features. This is done to show objects with internal parts or to show the moving object. Wireframe modeling programs allow the user to create a wireframe skeleton. In solid modeling, a complete solid model is created with all the color and depth. The two are usually combined, with a wireframe made first and then a solid model placed on top of it.
