i have been in contact with autodesk but no reply since monday.
i have audited and i have purged unused. i have also made new local files and tried it on a number of machines in the office.
when i either create a section of i try to open an existing section revit crashes with a fatal error.
the only thing i can think of that i did differently was copy objects from one level to another. i have tried to unlink any cad files and revit models and still crash.
today i just happened to try to erase all flexible ducts and did not get any fatal errors... this cant be due to my sections being cut all the while before with flexible duct in them. unless revit is becoming over loaded with flexible duct?
any ideas or someone who has had similar problems would be great.
thanks
