This command creates a profile (.PRO file) from a centerline
polyline and a surface model stored in a 3D grid file (.GRD) or
triangulation file (.TIN or .FLT). The polyline defines the
alignment of the profile and the grid defines the surface.
After selecting the reference surface file, there is a Profile
Options dialog with these options:
Link Profile To
Triangulation: This option will update the profile whenever
the reference triangulation is modified.
Type of Centerline: This
setting chooses the type of stationing for centerline curves.
Station by Another Reference
Centerline: This option uses a second reference centerline
for the stationing of the profile. The main centerline is used to
find the elevations on the surface and then these main centerline
positions are projected onto the reference centerline to get the
stationing. The reference centerline needs to extend along the full
range of the picked polyline in order to project correctly and
capture offsets along the entire length of the picked
centerline.
Profile Offsets: In
addition to creating the profile along the centerline, you can also
create profiles offset left and right.
