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.
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.
1) Host: HP nx6320 – 2cpu intel Centrino Duo 1.66Ghz – 1,49Gb – XP SP3
2) Host: HP Pavilion dv6 – Intel i-5-2410M 2.30 Ghz - 4cpu – 8Gb - Win 7 64
3) Host: HP Pavilion dv6 – intel i-5-2410M 2.30 Ghz - 4cpu – 8Gb - Win 7 64
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.
