As in the manual drafting of technical and engineering drawings, the output of CAD must convey information, such as materials, processes, dimensions, and tolerances, according to application-specific conventions.ĬAD may be used to design curves and figures in two-dimensional (2D) space or curves, surfaces, and solids in three-dimensional (3D) space. However, it involves more than just shapes. ĬAD software for mechanical design uses either vector-based graphics to depict the objects of traditional drafting, or may also produce raster graphics showing the overall appearance of designed objects. In mechanical design it is known as mechanical design automation ( MDA), which includes the process of creating a technical drawing with the use of computer software. Its use in designing electronic systems is known as electronic design automation ( EDA). The terms computer-aided drafting ( CAD) and computer-aided design and drafting ( CADD) are also used. CAD output is often in the form of electronic files for print, machining, or other manufacturing operations. : 4 Designs made through CAD software are helpful in protecting products and inventions when used in patent applications. : 3 This software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to create a database for manufacturing. A 2D CAD drawing A 3D CAD modelĬomputer-Aided Design ( CAD) is the use of computers (or workstations) to aid in the creation, modification, analysis, or optimization of a design. For other uses, see Cad (disambiguation) and CADD (disambiguation). Our Blocks are a mechanical constructions ie a conveyor, table, etc.'CAD' and 'CADD' redirect here. This I can do from top level/main drawing. I'm then able to turn off the water and electricity symbols/tags, that each of the blocks have. The Picture shows a small section of a plant layout (Can't show the whole thing for obvious reasosn). I have attached a before and after Picture. One of our blocks could for example could be a Vessel that has a valve and electrical tag/symbol to it, that we would like to be able to turn off from top level, once the block has been inserted to the main drawing. And sometimes the drawings gets messy if you have to many info tags on the drawings The info on the Blocks are usually used later, when we print out drawings for on-site installation. We use our 2D software for plant layouts only, and one of the features we would like to preserve, is the ability to turn on/off the Water, Electricity info that we have on each of our Blocks. So, at work, we're switching from ME10 to AutoCAD.
