CHAPTER 1 The Basics of auTocaD civil 3D
Modify the drawing scale and default object layers. Civil 3D understands that the end
goal of most drawings is to create hard-copy construction documents. By setting a drawing
scale and then setting many sizes in terms of plotted inches or millimeters, Civil 3D removes
much of the mental gymnastics that other programs require when you’re sizing text and
symbols. By setting object layers at a drawing scale, Civil 3D makes uniformity of drawing
files easier than ever to accomplish.
Master It Change BasicSite.dwg from the 100-scale drawing to a 40-scale drawing.
Modify the display of Civil 3D tooltips. The interactive display of object tooltips makes it
easy to keep your focus on the drawing instead of an inquiry or report tools. When too many
objects fill up a drawing, it can be information overload, so Civil 3D gives you granular con-
trol over the heads-up display tooltips.
Master It Within the same BasicSite drawing, turn off the tooltips for the Road A
alignment.
Navigate the Ribbon’s contextual tabs. As with AutoCAD, the Ribbon is the primary
interface for accessing Civil 3D commands and features. When you select an AutoCAD Civil
3D object, the Ribbon displays commands and features related to that object. If several object
types are selected, the Multiple contextual tab is displayed.
Master It Using the Ribbon interface, access the Alignment Style Editor for the
Proposed Alignment style. (Hint: it’s used by the Road A alignment.)
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″
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 avail-
able 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.
