I'm trying to import a DXF into GIS (I have QGIS, Arcmap 9.2, GVsig ) The file has been given a coordinate system & appears to be the right size, just in the wrong place. In Draftsight (or any other software that can read DXF) how can I set a correct coordinate system? I've been looking at the Draftsight resources but can't work it out as I have limited CAD knowledge.
I can't really affine this in QGIS as I have no base mapping, but I am sure I know the existing CS is out by 400,000m on x & 100,000 on y (OSGB Tile code SU) so if I could do this in Draftsight & re-save it it would come out correct. Many thanks for any help.
