This software reads and writes AutoCAD DWG files from 2.5 to 2009
progeCad Smart (for Windows) offers the best free CAD package on the market! If you're an architect or engineer, this is the one for you. Once you are ready for features such as pdf conversion and better photo rendering, the pro version will be waiting for you.
This software is better due to its AutoCAD capibility
The AutoCAD clone is exceptional and full of features without burdensome system requirements. If you can live with personal use restrictions and no reflection of post-2009 DXF file format revision, then go ahead and download this product.
This file is only 100mb, yet delivers everything you need for a starter pack. It is full of features and extras, these include: being fully 3D capable, vectoring raster images with Wintopo, and access to the vast ALE libraries (over eleven thousand pre-drawn blocks). It's safe to say this that this is a cutting edge drafting system. Don't mind the restrictions involved with using this software on Windows 7, there are plenty of options to accommodate this operating system.
Other important features to note include: IntelliCAD AutoLISP interpreter, oSnap like temporary point and snap, plus layers and blocks. Don't forget about the ability to edit xref, blocks, and hatches. There are options for both rendering and 3D shading. This is the successor to progeCAD Smart 2008 that we have all been waiting for!
