After creating a composite Construct with 3d xrefs in AMEP 2009 I tried exporting to a 3d dwf. AMEP2009 hangs at 5%. So then I tried to export to ACAD 2007 format, open in ACAD2008 and create 3d dwf from there. DWF is created, but when I open it in Design review 2009 SP1, fatal crash and system reboots everytime. Tried 4 times recreating dwf each time.
Ran recover/audit on ACAD-3d and export to 3d dwf all times.
Not sure if anyone else has found problems like this.
