Polyline to 3D Polyline
Click the Features | Change | Change To | Polyline to 3D Polyline command or right-click on a polyline and click Polyline to 3D Polyline to convert one or more selected polylines or spline polylines into 3D polylines. Each selected polyline is converted to a new separate 3D polyline.
The new 3D polyline uses the default line properties from the polyline. If the object name has not been changed from the default Polyline, the object is renamed 3DPolyline. If the object name had been altered, the custom object name is retained.
X, Y, and Z coordinates for each vertex can be changed on the Coordinates page in the Properties window.
