Thanks for the support. I have done some invistigation and here is what I have found.

The drawing is a rectangle of 130mm x 150mm with a scale of 1.000, when this is exported in either .dxf or .igs it imports into DesignCad 3D Max 15 as 5.1181mm x 5.9055mm the same goes for ArtCAM Pro 8.1. If I do the reverse and import to Pro/Eng from DesignCAD it come in massive (much larger than the size of the template.
