EPLANT

ZWCAD versus AutoCAD

ZWCAD is a good alternative to AutoCAD. It is affordable, uses the same dwg format and it has a better performance.

The table below shows the results of a benchmark: Isometric and cpf file extraction and 2D Plan generation from EPLANT-Piping V2017.0 running on different OS and CAD systems.
Times for Isometric and PCF Extraction are mean values using a real 3D model with 122 piping lines, with a mean quantity of 45 different MTO items per piping line. 2D Plan Extraction times were obtained with a 3D model with 2875 components.

When comparing execution times pay attention to the host machine: all but the first one are Virtual Machines either running XP or Win 7 64 bits.

AutoCAD A simple look at the performance of different versions inequivocally shows the extent of performance degradation with new versions: the much publicised "Productivity Gains" are clearly not here.

ZWCAD uses the same dwg format (and therefore its drawing files are 100% compatible with those of AutoCAD) and has a similar user interface, although more simple than the current versions of AutoCAD.

A license enables to use an EPLANT module on any of the supported CAD system and versions.

Download ZWCAD and try it for a month.
