This command will prompt you for
samples of the elevation labels, the leaders, and the polylines to
convert. The program uses these samples to know the layer names for
the labels and linework to process. Then select all the labels and
leaders for the polylines you want to convert. You will then be
prompted to enter in an elevation to add to label values. Often
times elevations are abbreviated to save time and space. If every
elevation in a drawing is in the 800s instead of labeling every
elevation 817.85, 817.40, 817.30 sometimes, like in the above
example, they are listed 17.85, 17.40, 17.30. This command allows
you to add a given amount, such as 800, to every label elevation to
produce the correct elevation in the drawing. 
Carlson TakeOff searches for all
leaders and gathers their associated
text. If the program finds different labels in the elevation text,
then this dialog box allows you to select the text you want to
create 3D polylines. In this example you might want to use
elevations followed by TC. This dialog box allows you to select
that text and exclude the other text which is not to be used in the
elevations of the polyline, such as FS.
If you are creating 3D polylines from multiple elevation labels than this dialog box will allow to offset certain labels by a given amount. In the above example you can offset an elevation labeled FS by .50 so that it matches vertices set by TC labeled elevations. The vertices elevated in this command will appear as control vertices in the command Edit-Assign Polyline Elevations. It can also be used in conjunction with other 2D to 3D commands to elevate polylines by more than one method.
