For me ActCAD is my Swiss knife among CADs
ActCAD is small but powerful, almost universal CAD software with self license transfer mechanism.
With ActCAD Pro and new BIM in perpetual version can work anywhere, anytime with minimum requirements for PC, Windows and Internet options.
Low-cost and Life-time ActCAD is almost equal with expensive CADs.
For practical Engineers and Architects, ActCAD with 2D, 3D and with BIM options is more than you really in designing or on a construction site need.
ActCAD is a real engineering CAD program because all logic is followed
with CAD standard as a CAD program, that's why it's easy to use.
ActCAD Professional supports all versions of DWG and DXF formats.
With a good selection of plugins ActCAD can convert raster images to Vector a and supports PDF 2D import-export as well as export to 3D PDF. For all that to be complete, ActCAD made sure you also had the option of 3D Render with Artisan. What needs more :)
It is especially amazing that the team that develops it is committed to eliminating bugs, refining, innovating and supporting them so that ActCAD in all variants has a bright future. Review collected by and hosted on G2.com.
