2D Polyline
A 2D polyline is a line of connected points that have the same
elevation. This command lets you digitize a 2D polyline by picking
points along the lines on the drawing. It prompts you first the
Polyline 2D Options Dialog
for entering the layer name. Prompt For Polyline Elevation option
allows you to enter the elevation for each polyline, otherwise all
2D polylines have 0.0 elevation. Auto-Zoom mode would automatically zoom
the display to center around the last point when you get near the
edge of the screen while picking points. There are three ways to
enter a layer name, Use current
drawing layer, Select from a list of layer name, or
Pick an entity on the
screen to get its layer name. While digitizing a polyline, the
command keeps prompting you to either pick the next point or
press 0 to create an Arc
until your press
Enter to finish digitizing.
Press A on the puck or
enter Close on the keyboard
to close the polyline on itself. You can define an Arc by Radius, Arc length, Chord
length, Delta angle, or by simply picking 3 points along the arc.
If at any point you make a mistake, press B on the puck or enter Undo on the keyboard to remove
the mistake and then continue to digitize. After finishing a
polyline, the command prompts you to digitize another polyline
until you press B or
enter No.
