This command creates a .PRO file from points and a
centerline that is represented by a polyline or centerline file. The
elevations of the profile are derived from the elevation of the points
and the stationing for these profile points is calculated from the
distance along the centerline. The points must be within the offset
distance from the polyline in order to be included in the profile. The
profile is created by projecting the points perpendicular onto the
alignment to determine the station and the elevation comes from the
point elevation. The
polyline or centerline should be drawn (or defined) in the direction of
increasing stations. The points can be selected from point
entities in the drawing (Screen), by point numbers from the current
coordinate file (Numbers), or by point group as defined by the Point
Group Manager (Group).
PROfile file to Write dialog box: Enter a new profile file
name to write.
CL File/<Select polyline that represents centerline>: pick
a polyline or choose C for Centerline
Select Centerline file if Centerline option is used. If the desired
points are further from the centerline, enter a
larger maximum offset tolerance.
Note: for all selected points, the points should be located
on the real Z axis.
Select the Carlson points along the centerline.
Select objects: Select the point entities.
