When you select more than two profiles to create a loft or swept blend form in the adaptive / conceptual mass environment, Revit does not let you nominate the profile order. This means that it often fails to create form when the profiles are not very close to each other or if they are at different angles to each other (it gives a message about self-intersecting geometry). Many of these 'fail' error messages could be avoided if we could nominate the profile order when creating a form. Revit sometimes fails to regenerate a form when you move or adjust the profiles - presumably for the same reason (it gets the order wrong). In fact it even comes up with a message saying 'press the Reorder button' to correct the problem. Of course there is no 'Reorder Profile' function available to us, although it must once have been in a test version of the software, hence the warning message.
