I'm having a problem when I'm trying to export parts of my drawing to WMF file format.
I have a large drawing of the entire building layout today, I need to break this down into several smaller pieces for easier management in Visio. Tried importing the entire dwg file into visio, but since the drawing is made up from alot of relative drawing links, I cant get that to work, this is why I need to work with WMF format.
 
I've been adjusting the viewport and exporting the visible area. But no matter how I do it, the pixelsize of the WMF files always seem to differ from eachother.
 
Is there another way (working) to do this, or is the WMF format just not suitable for this typ of work? 

What is "relative drawing links"? If you mean xrefs, you can bind these xrefs into the main drawing and then copy your drawing in one go. You can also try to simplify the drawing by projecting it into 2D (if it is 3D), or by copying it to Visio in several pieces.
