AllyCAD Freeware version allows users to experience the ease-of-use as well as the advanced functionality of AllyCAD. As mentioned, it is a full working version of our highly acclaimed AllyCAD Professional and is limited only in terms of its CAD drawing size (150 KB) - this limitation excludes hatching, bitmaps and images. AllyCAD Freeware is popular among users that have smaller drawing requirements and has further become increasingly popular among various academic institutions as a CAD student version.
