The Bottom Line
Create a series of lines by bearing and distance. By far the most commonly used command
when re-creating a deed is Line by Bearing and Distance.
Master It Open the Mastering Lines and Curves.dwg file, which you can download from
www.sybex.com/masteringcivil3d2010. Start from the Civil 3D point labeled START, and
use any appropriate tool to create lines with the following bearings and distances (note that
the Direction input format for this drawing has been set to DD.MMSSSS):

Use the Inquiry commands to confirm that lines are drawn correctly.
Master It Continue working in your drawing. Use any appropriate Inquiry command to
confirm that each line has been drawn correctly.
Create a curve tangent to the end of a line. It’s rare that a property stands alone. Often, you
must create adjacent properties, easements, or alignments from their legal descriptions.
Master It Create a curve tangent to the end of the first line drawn in the first exercise that
meets the following specifications:
◆ Radius: 200.00
◆ Arc Length: 66.580
66 CHAPTER 2 BACK TO BASICS: LINES AND CURVES
Create a best-fit line for a series of Civil 3D points. Surveyed point data is rarely perfect.
When you’re creating drawing linework, it’s often necessary to create a best-fit line to make up
for irregular shots.
Master It Locate the Edge of Pavement (EOP) points in the drawing. Use the Create Line
by Best Fit command to create a line using these points.
Label lines and curves. Although converting linework to parcels or alignments offers you
the most robust labeling and analysis options, basic line- and curve-labeling tools are available
when conversion isn’t appropriate.
Master It Add line and curve labels to each entity created in the exercises. Choose a label
that specifies the bearing and distance for your lines and length, radius, and delta of your
curve.
