Convert NCZ to DWG

Netcad software offers export of its own drawings (.ncz files) to several CAD formats as well as various raster, vector, GIS, CAD and other related file formats. In the case of DWG for, Netcad supports older format based on features of DGN-V8/DWG-DXF (2006), nevertheless this should be enough for the purpose of ncz to dwg conversion support.

Unfortunately, we do not know about any 3rd party software that can be otherwise used to convert to ncz to dwg, which means Netcad is likely your only option.
