Transparent commands can be issued at the Command: prompt while
running other commands without exiting the current command. The
transparent command will run and then return to the current
command. To run a transparent command, you can either type in the
command name or pick a button on the Transparent Command toolbar.
There are seven Carlson transparent commands. These commands can be
used at any command prompt that is for a point location.
'2: Gets the 2D (x,y) coordinate by point number from the current coordinate file. You can enter a single point number or a range of points (ie 1-10).
'3: Gets the 3D (x,y,z) coordinate by point number from the current coordinate file.
'CL: Gets a point by station-offset from a centerline. The
routine prompts for a centerline, station and offset left or right.
The position along the centerline can be specified by entering the
station, picking a point that gets projected onto the centerline,
or by a distance factor. The 'CL command can be used as a
Perpendicular From snap by picking a centerline and entering a
station to come perpendicular from (the routine defaults to the
station of the last point) and then entering an offset for the
perpendicular distance.
'CENTROID: Gets a point that is the centroid position for a
closed polyline. The routine prompts for the polyline to
process.
'TANGPT: Gets a point that is tangent to the selected centerline
or polyline. The routine prompts for the centerline, station and
distance. The station defaults to the position along the centerline
of the last picked point.
'BBPT: Gets a point by Bearing-Bearing Intersection. The routine
follows the same prompts as the Bearing-Bearing Intersect command
in the COGO menu.
'BDPT: Gets a point by Bearing-Distance Intersection. The routine follows the same prompts as the Bearing-Distance Intersect command in the COGO menu.
'DDPT: Gets a point by Distance-Distance Intersection. The
routine follows the same prompts as the Distance-Distance Intersect
command in the COGO menu.
