Shape file .prj file after export have no "PROJCS" specified.
As far exported prj file is following:
No matter, if I'll change projection (from Geographical to OSGB) of the layer in the project, result is always the same.
In attachment there is the file that have "PROJCS" in the projection file, I wish to get the same with GM.
This is .prj content from attachment:
As far exported prj file is following:
GEOGCS["GCS_WGS_1984",DATUM["D_WGS84",SPHEROID["WGS84",6378137,298.257223563]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]]

As the input I'm using DWG file.

After you load your shapefile, change the projection to OSGB using the Configuration dialog (Projection tab), not the layer options dialog. Afterwards, when you export the shapefile, be sure to check the option to write a PRJ file also.
