DXF import in Allegro (argh!)

N i z e

I'm desparately trying to import a vector based logo into a Orcad PCB 16.2. However, this for some reason suddenly seem impossible:

If I try to import DXF I never seem to be able to "view selected layers" (and thus never import anything). The dialogue does however show me DXF layer names (for instance the Cadence sample dxf has names similart to Allegro layers). Tried over 10 different versions exported to different AutoCad versions - but the format did not seem to matter. From what I read in this forrum and elsewhere Autocad version 2004 or 14 seem to be the better bets (can't find anything useful in the Cadence documentation). Out of desperation I've also tried with an ouline that I've positively imported and used for another board. Same results all over the line:

From an open .dra file I get:
Opening existing drawing...
   E- *Error* fprintf/sprintf: format spec. incompatible with data - "Format is 'dxf2a -$ %s -u %s -v %s -a %d %s %s %%s %s', argument #1 is nil"

From an open .brd the dxf2a.log reads:
  ERROR: Invalid program arguments.
  Terminating program.

Any hints on what I'm (or Allegro is) messing up here? I'm on the virge of trying a reinstall - but that'll probably just be complete waste of time...(!?)

Thanks and best regards,

 Anders

 PS: Seemingly it's impossible to scale anything in Allegro 16.2.?

    Sorry about the logomaker - your first post mentioned logos so I assumed you needed a company logo and not board outlines etc. When you import dxf you could try bringing in everything to a dummy layer (like Board geometry assembly notes / details) then to get a shape to be a voided shape try Shape - Compose Shape, select the layer etc in the options then window the inner contour, this creates a filled shape, then window select everything (inner and outer contour and you should get a voided 'o' shape. (Well this works in 16.6....)
