ABViewer vs DWGSee

ABViewer lets users view, edit, measure, convert, and print CAD files, 3D models, and raster images. It supports CAD, vector, 3D, complex, raster, and archive formats including DWG, DXF, STEP, IGES, PDF, STL, SVG, and ZIP. For 2D drawings, users can manage layers, blocks, dimension and text styles, snapping, comments, and markups. Measurement tools cover 3D distances, face heights, surface areas, and curvilinear edge radii, with section-view creation. Conversion options include STL, OBJ, DWG/DXF, supported 2D formats, and STEP or SAT/SAB export for parametric models. The software can generate CNC G-code from 2D drawings. Enterprise adds PDF-to-DWG/DXF conversion, batch conversion and printing, file comparison, and command-line features. ABViewer runs on Linux and Windows; Windows downloads include 32-bit and 64-bit version 16 builds. A free 30-day trial is available. Paid options include subscriptions and lifetime licenses. Professional user licensing starts at $30 a month, billed every three months.

DWGSee is a viewer and editor for DWG, DXF and DWF drawings, with tools to browse, measure, edit and print them. It also supports BMP, JPG, PNG, GIF and TIF images. Editing includes adding drawing objects and changing text, lines, layers and block attributes. Smart-snap tools measure length, angle, radius and area, while printing handles individual drawings or batches. For review, it can show two drawing versions in split windows, synchronize zoom and pan, and highlight differences. Markup can remain in a separate overlay or be added to a DWG as layers, lines and text. The feature list includes encryption and password protection. Pro exports to PDF and raster images; Standard does not include those exports, while copying a drawing into Word as a vector image is listed for Standard and CAD but not Pro. Platforms listed are Android, macOS, web and Windows. Free access and a trial are offered; paid lifetime licenses start at $69, paid once, with one year of free upgrades for Standard and Pro.
