2D to 3D Polyline by Start/End Elevations

This command allows you to convert a 2D polyline to a 3D polyline by specifying the starting and ending elevations of the polyline. All intermediate polyline vertices elevations are linearly interpolated from these end point elevations.

Prompts

Select polyline to assign elevations:
Enter starting elevation: 109.85
Percent/Ratio/<Enter ending elevation>: 112.16
Select polyline to assign elevations (Enter to End): press Enter
