As FSBuild does not appear to support PFE as it's not on the list of software to export to, I read Dave March's post to just use the FS2004/FSX option. I used FSBuild to create a flight plan and used the FS2004/FSX option to export but have no idea where the flight plan went. I assume that FSX stores them in USERS\MYNAME\MYDOCUMENTS? I looked there but could not find any .PLN files. I guess I need to post in the FSBuild forum.
Thanks
