"Wall by face" tool in 7.0

[rob.goetze]

In experimenting with massing, I noticed that the "Wall by face" tool, when selected, allows one to specify start level and height on the options bar.

However, if I chose (for example) Level 4 to Level 8, the resulting wall would still start at Level 1. In the properties of the resulting wall, Revit had listed the right level as the Base Constraint, but had added a negative Base Offset.

As well, there was sometimes inconsistency between the height chosen and the resulting height... in these cases, it seems that Revit had added a sketch to the wall to make it higher than the specified Top Constraint.

Has anyone encountered similar problems and -- ideally -- solutions?

When option to 'Pick Faces' for wall creation is used, resulting wall gets elevation profile that matches the shape of the face.

Base and top constraints are used only to determine which faces of wall to attach when such command is used, and to determine shape of the wall if elevation sketch is removed.

If you using face to determine line of the location line of the wall, not the shape of elevation profile, use Pick Lines option (which is on option bar to the left of 'Pick Faces' option).
