Too many have clumsy and out of date interfaces and fail to provide either a preview of the CAD file, a usable block, or a free DWG file altogether.

However there just aren’t 10 CAD block sites that are worth mentioning. Where can I download free CAD files? …The Best free CAD block librariesīefore writing this article, we had set out to provide a top 10 list of the best and most relevant free CAD block libraries available. The term CAD is an abbreviation of Computer Aided Design, and where you may see “auto” placed in front of it (making AutoCAD) this is simply in relation to Autodesk’s CAD program “ AutoCAD”, which also happens to be the industry standard for 2D drawing and thus the most popular. They can also be used to provide the drawing with additional information, such as a lighting or electrical layout. Why are they used?ĬAD blocks are ultimately a form of representation that add depth and meaning to 2D and 3D drawings, by providing the drawings with scale, context and legibility, through the use of furniture, vegetation and people. That said however, with the increasing amount of architects and architectural practices now using BIM, and there are many libraries available that also provide 3D CAD blocks to suit these related programs such as Revit, Vectorworks and ArchiCAD. In the case of this article and in fact for their general use within architecture, they are most commonly used to populate 2D CAD drawings, and can be anything from a tree, person, item of furniture, electrical symbol …anything!

Firstly through and for those that do not know, a CAD or AutoCAD block can be defined as a group of 2D or 3D lines and/or elements that are grouped together to form an object in a DWG file format.
