Import points: Station-Offset-Elev

Import points: Station-Offset-Elev

Creates points along an alignment by importing points from an ASCII (text) file that contains station, offset, and elevation information.

The file you import can contain the station, offset, elevation, and description of each point. The elevation can be expressed as either a single value (elevation) or a rod reading with instrument height (rod, hi).

ASCII (text) files that use the following layouts (formats) can be imported:

• Station, Offset
• Station, Offset, Elevation
• Station, Offset, Rod, Hi
• Station, Offset, Description
• Station, Offset, Elevation, Description
• Station, Offset, Rod, Hi, Description

Use commas or spaces as delimiters (separators) in the file. Include one or more comment lines in the file by putting a semi-colon (;) or a pound sign (#) in the first column of a comment line.

The following is an example of data in an ASCII (text) file that is formatted using the Station, Offset, Elevation format:

#station, offset, elevation: subdivision 1

0 20.0 112.00

10 23.5 114.64

20 22.5 116.56

30 23.0 116.32

40 22.0 115.83

The first line in this example is a comment line that is ignored when the points are imported. Each of the remaining lines contains the station, offset, and elevation for a point. The file is delimited by spaces.

Before you import the file, you are prompted to describe the format of the ASCII (text) file. You can also be prompted to specify invalid indicator values for station/offsets, elevations, and rod heights.

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.
