CadStd is a general purpose, easy-to-learn CAD/drafting program for creating professional quality mechanical designs, house plans, blueprints, schematics and charts utilizing ANSI drawing standards.
CadStd Lite can export files as DXF so you can share your drawings with friends who have other CAD programs like Autocad. The Pro version can create isometric projections from orthographic views, and has powerful commands like offset, trim, fillet and chamfer.
Export drawings in formats like DXF, SVG, HPGL/1 or use copy clipboard to paste images into Office and other applications. Import DXF, HPGL/1 and Gedcom files.
Love this program! I use it all the time!
