Had lots of problems trying to export to DR which can't then open the file. Narrowed it down to this MVB model of a sink/tap. If ACA can model it, shouldn't DR be able to display it?
ADR is a DWF viewer, and it uses the free dwg viewer (requires the ACA OE to be installed I believe) to convert a file, if it all works: why not export to DWFx from ACA first, if you already have ACA? Skip a step by only using the software you know and control fully.
