DXF

I have imported a DXF file which has uploaded but is not displayed. The DXF originated from Golden Software Surfer and exported as DXF.  Coordinates system used is the same for both program - OSGB 1936.

The file is noted as 'include on Map' within the 'Manage Data Sets'.

However, when checking 'styles;' there are no points/ lines/areas noted.

Can you help?
