Netsys - Unable to access file -> Vectors not read in


I'm having an issue when setting up a Netsys calculation and Importing a DXF. I get a pop-up reading 'Unable to access file' followed by 'Vectors not read in'.

This results in the DXF not being imported.

I also set up a CIBSE gain calc and managed to import a DXF without any issues.

Many thanks,
