Polyline 2D to 3D by Points

This tool converts 2DPolylines and LWPolylines to 3DPolys using adjacent nodes with optional transition. In other words if point or insert objects exist at the endpoints of the original polyline, that will determine the elevation assigned at that point. Even though the point will ideally be exactly on the endpoint, you can specify a search distance.

Keyboard Command: PlnCnvNod

This tool can also assign elevations to points (along the polyline) that have no found point for assignment. It interpolates and does a transition from the last point of found elevation to the next point of found elevation.

Procedure:

1. Evaluate the polylines to be processed to determine if they contain arcs. If so, see the note below.
2. Issue the command from the menu or by alias.
3. Select the polylines to process.
4. Specify the maximum distance the point or insert can be from the endpoint to be considered found.
5. Designate if you wish to assign elevations to intermediate points by transition.

Notes:

• If any of the polylines to be converted contain arcs, use ToolPac's Remove Arcs tool to convert the arc segments to chords. The elevations of these added points (along the curve) will be established if the transition option is set to yes.
