I use Adobe's Pagemaker which is similar to InDesign.
I also find that importing of pdf's to be most convenient, especially as you can set it up in plotmaker(or archicad) to publish to pdf, thereby ensuring that the pdf link in your InDesign document is the latest version.
Other vector formats which work are
.emf & .wmf. I usually prefer to save them from plotmaker. Sometime drawings are too large for export to these 2 formats.
I've also
copied & pasted directly from Plotmaker and Archicad. Sometimes pasting from .pmk's works better. The resulting paste in Pagemaker is a vector format, so if I crop or enlarge I don't loose quality. I use the same technique to quickly import vector quality images into
Powerpoint.
