ABOUT: These free files are mostly saved in an AutoCAD 2000 DWG format. So you can open them in whatever version of CAD software you have. They have been carefully screened and cleaned. Most blocks are on layer 0, byblock or bylayer and insert at 0,0,0. A PURGE and AUDIT has been run on each block.
These simple details will be useful in any DWG compatible CAD software package. While we have created these drawings in AutoCAD, they are compatible for use in other 2D software. For example: BricsCAD, Chief Architect, DesignCAD 3D Max, DraftSight, LibreCAD, Microstation PowerDraft, nanoCAD, ProgeCAD, Sketchup, Solidworks, TurboCAD, Vectorworks, GstarCAD, IntelliCAD and ZWCAD,
