Shortcut Key: V
Draws a single or multi-segment 2D or 3D line. A valid line entity must contain two or more points.
Point 1: Beginning of line
Point 2: End of first segment
Point 3-n: End of second and subsequent segments (optional)
When you have set the points, press Enter or double-click the mouse to end the command.
NOTE: This command is similar to the Plane command except the Plane command creates a surface instead of a line.
TIP: You can use the Make Plane command to convert lines into planes so they can be shaded.
