# Create lines

You can create lines interactively, from known coordinates, or from distance and bearing values.

## Create lines interactively

To create lines interactively by clicking the map, complete the following steps:

1. On the ribbon, click the Insert tab.
2. In the Measurements group, click Distance and Direction .
3. In the Distance and Direction pane, click the Line tab.
4. In the Create Using section, choose the Points option.
5. Click Map Point Tool .
6. Click a location on the map to designate the starting point of the line.
7. Click a location on the map to designate the ending point of the line.

A line is created and added to the map.

## Create lines from known coordinates

To create lines using known coordinates, complete the following steps:

1. In the Distance and Direction pane, click the Line tab.
2. In the Create Using section, choose the Points option.
3. Enter a coordinate in the Starting Point text box.
4. Enter a coordinate in the Ending Point text box.
5. Press Enter or click Create Line.

A line is created and added to the map.

## Create lines using distance and bearing

To create lines using distance and bearing, complete the following steps:

1. In the Distance and Direction pane, click the Line tab.
2. In the Create Using section, choose the Distance and Bearing option.
3. Enter a coordinate in the Starting Point text box or click Map Point Tool and click a location on the map.
4. Enter a value in the Distance/Length text box.
5. Enter a value in the Angle text box.
6. Press Enter or click Create Line.

A line is created and added to the map.

## Change tool units

You can change the units the tool uses to display and label outputs.

• Use the Distance/Length drop-down list to change the unit of measure.
• Use the Angle drop-down list to change the unit of measure.
• Use the Line Type drop-down list to change the line type.

### Line type

The Line Type drop-down list provides the following options:

OptionDescription

Geodesic

The shortest line between two points on the earth's surface on a spheroid (ellipsoid). One use for a geodesic line is to determine the shortest distance between two cities for an airplane's flight path. This is also known as a great circle line if it's based on a sphere rather than an ellipsoid.

Loxodrome

A loxodrome distance is a line of constant bearing or azimuth. Great circles are often split into a series of loxodromes, which simplifies navigation. This is also known as a rhumb line. Unlike geodesic, it is not the shortest distance between two points.

Great Elliptic

The line on a spheroid (ellipsoid) defined by the intersection at the surface by a plane that passes through the center of the spheroid and the start and endpoints of a segment. This is also known as a great circle when a sphere is used. The great elliptic type allows you to create lines only.
