From the developer:
progeCAD offers an affordable way to read and write AutoCAD files, using similar commands and toolbars as used in previous releases of AutoCAD itself. Many choose progeCAD over AutoCAD LT because of it's low cost (currently a little over AUD $500) and features like 3D modelling and AutoLISP which are blocked in AutoCAD LT. progeCAD is commonly used in a wide variety of industry domains, including building design, electrical and plumbing, telecommunications and fibre-optic diagrams, civil land survey, engineering, fabrication, joinery and much more. With progeCAD Professional 2016, a CAD drafter can create very large complex drawings and save directly to AutoCAD or AutoCAD LT without data loss or conversion.
