What ABViewer is
ABViewer is software for viewing, editing, measuring, converting, and printing CAD files, 3D models, and raster images. Supported formats span CAD, vector, 3D, complex, raster, and archive types, including DWG, DXF, STEP, IGES, PDF, STL, SVG, and ZIP. For 2D drawings, users can work with layers, blocks, dimension and text styles, and snapping, and add comments and markups. Its 3D tools measure distances, face heights, surface areas, and curvilinear edge radii, and create section views. The software converts models to STL, OBJ, DWG/DXF, and supported 2D formats; parametric models can also be exported to STEP and SAT/SAB. It generates CNC G-code from 2D drawings. ABViewer runs on Linux and Windows; the download page lists version 16 in 32-bit and 64-bit Windows builds. PDF-to-DWG conversion is limited to Enterprise, which also includes batch conversion and printing, file comparison, and command-line features. A free 30-day trial is available. Professional licenses start at $30 a month, billed every three months.
