Free 2D CAD Drawing Software

What is CAD?
Computer-aided design or just CAD is the use of computer in the formation, modification, analysis, or setting the behaviour of a design. CAD software increases the efficiency of the designer, better the designs quality, improves documentation, and manipulates the database formed for manufacturing. The output of the CAD is often in the form of electronic files. Following are some CAD software discussed.To get more news about free online 2d drafting, you can visit shine news official website.
Librecad is open source software that can run on many operating systems. This is good 2d cad software that will be helpful to anyone building something as well as graphic designers that want to replace t squares, triangles and other precision drawing equipments. The readable file formats are.dwg and .dfx and writable file formats are .dfx, .jpeg, .png and .pdf.

DraftSight is a 2d vector graphics package. It is fully UI but also has a command line interface which borrows heavily from the industry standard AutoCAD software. It is made by Dassault Systèmes. Draftsight is a medium which lets you create, edit. View and manipulate any sort of 2D drawing. It has productivity tools; it has an API, a friendly interface for user which makes it easy to use. It allows you to make use of existing DWG files and create new ones with ease and comfort.

The intended users are architects, engineers and students.
Mostly used in AEC, aerospace, construction, energy and many more industries.
Important features include 2d drawing, advanced surfacing, conceptual design, meld design, drag geometry, copy surfaces, annotations, construction modelling, landscaping tools and many more
Main functionality is assembly modelling and documentation.
QCad is made by RibbionSoft GmbH and is designed to work on multiple OS such as Mac, Linux and Windows. QCad helps you to create many 2d models using various design features. As soon as you start your model, you will want to produce it, QCad analysis tool helps you in making error free 2d designs.

Important features are 2d drawing 3d modelling and parametric modelling, Archive and share, command line, copy details, symmetry check analysis, stairs and railings, walls, doors, windows, 2d circuit design, electrical symbol library, hole tables and toggle flat display.

Nanocad is the ultimate CAD software for drawing and drafting. It is fast consistent and simple. It is used by millions of designers and engineers around the globe. By default it produces native DWG files; the user can create dwg drawing design according to their needs. It gives the benefits of constructing and editing technical drawings. It has an operative system which helps to establish user friendly drawing interface and an open API. It is available through a low cost annual subscription including updates and priority online support.librecad is a very useful tool for creating precise professional 2d drawings quickly and easily.

Solid edge is cad software manufactured by Siemens which aims at each process of development – 3d designs, simulation, data management and many more. Solid Edge provides us with innovation and motivates you to design something using synchronous technology. This technology helps in designing faster and sharper without the constraints of native 3d modelling. Solid Edge provides fully functional mobile design and collaboration, with access to processes of designs at any minute and any place. Using SolidEdge, you can implement a powerful and intuitive 3D design portfolio on your terms.

AutoCAD is cad software developed by Autodesk in 1982. It is used for architecture, construction and manufacturing of blueprints and their actual products i.e. engineering plans. It was released for desktop computers but since 2010 Autodesk released the mobile versions and web versions of AutoCAD as well.

AutoCAD provides the privilege, to students and educationists , of using AutoCAD freely i.e. the student version. The student version of AutoCAD is somewhat identical to the commercial version of AutoCAD with one difference that DWG files created or edited by a student version have an internal bit-flag set. The work done on student version cannot be used for commercial use.
