now ive upgraded my architectural desktop 3.3 to 2004 the merge function does not seam to work. Ive my plans in CAD where i was about to merge into archicad8 but it doesnt bring up the window that it normally brings up. any ideas?
You could always try the IFC import/export utlity. There are beta versions of IFC 2x add-ons available for both ArchiCAD and ADT 2004.
The ArchiCAD version is available on the GS website at http://www.graphisoft.com/support/ifc/beta_download/
and for ADT you should visit http://www.team-solutions.de/
The ArchiCAD add-on is available free of charge, but there is a charge for the ADT add-on (€398). I have tested the output from the ADT add-on imported into AC and while there are a few minor issues, the results are pretty good.
ADT 2004 supports saving as DWG in different flavours. Weéve had some troubles with this as the list of exporters in our classroom was different when launching AutoCAD with a different set of startup commands...
