All... In the new ADT 2005 (Beta 3), there are some new properties added for a Aecwall. They are "roofline" and "floorline". Accessing these two properties will be extremely helpful to me because I need to get the coordinates of certain walls that have had either their roof line or floor line edited. Before this BETA there is no way to get access to these coordinates other than using ObjectARX, which I have been doing in previous versions. But I need access in VBA... and the problem is that I cannot get either of those 2 properties to give me any info. They just keep causing an error when I try to get their values. Even when I stop my program while debugging, these properties do not show up when I place a "Watch" on a particular wall. Is this just a bug in the the ADT 2005 BETA, or is there another way to get this info? Any suggestions? Thanks, Chris Cox
