vfcontour

This tool interacts with raster entities and existing vectors to create AutoCAD
3D polylines.

When using the 3D Polyline Follower, you can either draw a polyline fence
that intersects raster contours, or you can select an existing polyline.
ProdNameShort then follows the polyline, pausing at each intersection to
prompt for elevation. At each such 

 (page 395), the follower

automatically inserts a vertex and prompts you to enter elevation data. You
can reference the elevation of existing vectors by using OSNAP to place the
polyline vertices on these vectors. When the follower pauses at a vertex,
ProdNameShort uses the elevation values of the intersecting vector entity as
the default value when it prompts for elevation.

At each vertex, you can take one of the following actions:

■

Enter an elevation.

■

Press Enter to accept the current elevation value.

■

Interpolate the value based on the previous and next elevation.

■

Use the elevation value of an existing vector that you specify.

■

Undo the last elevation entered.

■

Skip the current raster impact point.

■

Insert another vertex, then enter an elevation value for it.

■

Move the current vertex.
