This command works with 2 crossing 3D polylines, adding one or more
vertices to one of them at the virtual point of intersection to match
the elevation of the other. The 3D polyline that is vertically
unchanged is referred to as the "Main 3D polyline", the 3D polyline
that is edited is referred to as the "Side 3D polyline". The
command uses the 2 vertices on the Main 3D polyine on either side of
the virtual intersection to determine an interpolated elevation on the
Main 3D polyline at the point of virtual intersection, and adds a
vertex on the Main 3D polyline at that location with the calculated
elevation, but the vertical characteristics of the Main 3D polyline are
otherwise unchanged. The Side 3D polyline gets a new vertex at
the virtual intersection with the same interpolated elevation, thereby
changing it's vertical definition as much as necessary to match
in. The characteristics of the transition are controlled by the
settings in the Merge Crossing 3D Polylines dialog box.
Select the Main 3D polyline:
pick the 3D polyline that will
determine the crossing elevation, but will remain eseentially unchanged
Select the Side 3D polyline: pick the 3D polyline that is be changed to
match the Main 3D poyline elevation at the virtual intersection
Adjust variables as desired in Merge Crossing 3D Polylines dialog
box, pick
OK.
