HyCAD

HyCAD 5.35 is a compact, highly functional FREE 2D CAD utility. All "normal" CAD features are available. Content can export in raster (.BMP, .JPG, .PNG) or vector formats (.DXF, .Xmg, .DWG, .EMF, .Wmf, .EPS, .SLD, .SVG, .CGM, .PLT, .HGL, .PDF).  File import employs similar formats.

Even more useful is HyCAD's abilty to vectorize directly into a CAD environment.  The vectorize function is both simple and  excellent. Results can be  immediately usable as toolpaths.  Click on the image to access HyCAD web resources.
