6 If you selected End Current Polyline If Closed Loop Detected, specify the
tolerance distance in one of two ways: enter a numeric value, or click
Pick and click two points in the drawing. Polylines whose endpoints fall
within this distance will be automatically closed.

7 If you want to control how ProdNameShort draws the polylines and
contours produced by the follower, select Post Process Points. Optionally,
move the Polyline Deviation slider to control how closely ProdNameShort
imitates the raster polyline or contour.

High deviation creates a polyline with fewer points that is less faithful
to the original raster. Such polylines use less system resources.

Low deviation creates a polyline with more points that more closely
matches the raster path. Such polylines use more system resources.

8 In the Contour Settings section, select the type of entity the Contour
Follower creates in the Contour Creates list.
NOTE The follower can only create contour objects if ProdNameShort is
running on Autodesk Land Desktop. If you are running on Autodesk Civil 3D,
you can add the contour data to the definition of a TIN surface.

ELEVATION assigns an elevation value based on the AutoCAD
ELEVATION variable.

■
Zero assigns an elevation value of 0.

ProdNameShort adds or subtracts this amount from the last elevation
value you entered to create a suggested elevation value.
