Interpolates a point at a specified elevation between two control points.
Define the interpolation region by specifying the start and end control points, or click near the start point of an object.
Point settings, styles, layers, point groups, and description keys can all affect how a point is created or how it is displayed in the drawing. For more information, see Before You Create Points.
To create points at an elevation by interpolating between two points
- Select settings and create styles, layers, point groups, and description keys. For more information, see Before You Create Points.
- Home tab
Create Ground Data panel Points menu Create Points - Interpolate By Relative Elevation 
. - Specify the interpolation region by doing one of the following:
- Pick a point in the drawing and enter an elevation for the first point. Specify the second point and then either enter D to specify the difference in elevation between the two points, or enter S to specify the slope from the first point to the second point.
- Use Transparent commands to specify the point.
- Enter E, and select an arc, line, feature line, lot line, or polyline. Enter the elevation and then specify the offset distance by either entering the distance, picking a point, or using Transparent commands.
