Are you entering a field where you may have to work with computer-aided design (CAD) and AutoCAD? Do you need to learn the difference between them? Computer-aided design is the general term that applies to the use of computers in the design of houses, office buildings, interiors and anything else that previously required hands-on drafting. AutoCAD is a specific piece of software used by many architects and designers for commercial design purposes.
Computer-aided design, or CAD, is designed to take basic geometric shapes and manipulate them into a specific design. CAD applications are computer-driven, allowing designers to collaborate from anywhere in the world via the Internet. CAD applications eliminate the need for the teams of onsite drafters that were formerly used to create designs for industry.

AutoCAD is a CAD application that was developed by Autodesk, Inc., in 1982, to aid programmers in all aspects of 2D and 3D design . Today, the company has over 80 different products that address all phases of design, including manufacturing, infrastructure and building. AutoCAD is not only used in industry, but in the entertainment and advertising world to create visual 3D effects.

CAD and AutoCAD use a system of algorithms to manipulate primitive objects into a desired shape. Meshes are formed using a system of points and vector lines on an XYZ axis to enable 3D drawing. The images created, called vectors, can be manipulated in size and orientation. The programs can also manipulate bitmap images through utilizing digital pixels.

CAD software not only produces images, but also provides documentation and material reports. A drafter has the advantage of being able to test the design before it is implemented. This allows drafters to analyze the integrity of the design in various conditions prior to presenting to a customer.

In a word, CAD including AutoCAD, AutoCAD is a kind of CAD, so both of them include dwg and dxf files, and they are widely used nowadays, but both of them can not be viewed on different computer systems. thus, it is inconvenient for people to share their dwg or dxf files to others. But, it is well known to us that pdf files can view on different computer, so we can convert dwg and dxf to pdf files, then we can share them easily with our workmates or customers. But how to convert dwg to pdf ? Here, I tell you a dwg to pdf converter which is a tool that helps you to convert dxf to pdf as well as dwg and dwf to pdf files even without the use of an AutoCAD. This tool enables you to convert AutoCAD DWG and DXF files to vector PDF in batches in an efficient time. There is no need to use a stand-alone utility AutoCAD.
