Hi, I run Archicad 12 and AuotoCAD 2010. I am following the steps outlined in TechNotes "How to Superimpose a 2D Floor Plan onto a 3D Model" and I can pull an Ordnance Survey plan into the model as described but it is not coming in to scale and it is also distorted, in the 'y' axis I think. Can anyone help, I've been ont his for days now. Many thanks Lob
