CHAPTER 1 GettinG Dirty: the Basics of civil 3D
Object Layers Tab
Setting object layers to your company standard is a major part of creating the feel you’re after
when using Civil 3D in your office. The nearly 50 objects described here make up the entirety of
the Civil 3D modeling components and the objects you and other users will deal with daily.
The layers listed in this dialog by default reflect a modified AIA CAD Layer Guideline as part
of the National CAD Standard (NCS). This layering standard is built into many places in Civil
3D’s templates and is becoming more widely adopted in the land-development industry. In addi-
tion to being fairly comprehensive and well known among engineering firms, the NCS has the
benefit of being the roadmap for the future in terms of out-of-the-box content from Autodesk.
Adopting this standard means you’ll have fewer things to change with every release of the soft-
ware. Nevertheless, it is important that every user know how to modify these defaults.
One common issue with the shipping templates is that the templates assume road design is
the primary use of alignments. Use the following procedure to change the Alignment setting to
the NCS for laying out a sanitary sewer:
1. Click the Layer column in the Alignment row, as shown in Figure 1.5.
2. In the Layer Selection dialog list, select C-SSWR-CNTR and click OK.
One Object at a Time
Note that this procedure only changes the Alignment object. If you want to change the standard of
all the objects, you need to adjust the Alignment Labeling, Alignment Table, Profile, Profile View,
Profile View Labeling, and so on. To do this, it’s a good idea to right-click in the grid view and select
Copy All. You can then paste the contents of this matrix into Microsoft Excel for easy formatting
and reviewing.
