Not so long ago I wrote a review about Free Online PDF to DWG Converter by CADSoftTools and now I want to introduce ABViewer that is a software also developed by this company. According to the description from the website ABViewer is universal software for working with drawings. And yes, this software can be really called universal because: - it supports a large number of formats including AutoCAD DWG/DXF, SVG, EMF, PLT, STEP, IGES, STL, CGM, etc. - it enables to view, edit, convert, measure, print, etc. I'm not going to write about all features, only about things I use in my daily work.
