Run-time error '13 when importing a DXF

Good afternoon,

Please see the attached cleaned up DXF file, together with the corresponding error message.

When I attempt to import this DXF into Hevacomp to do some pipe sizing calculations, the software flags up a run time '13 error.

Does anyone know what the issue could be and how to resolve it?

Your assistance would be greatly appreciated.

Thanks.

Alex Rowe
