CHAPTER 1 GettinG Dirty: the Basics of civil 3D
The Override column shows whether the current setting is overriding something higher
up. Because you’re at the Drawing Settings level, these are clear. However, the Child Override
column displays a down arrow, indicating that one of the objects in the drawing has overridden
this setting. After a little investigation through the objects, you’ll find the override is in the Edit
Feature Settings of the Profile View as shown in Figure 1.8.
Notice that in this dialog, the box is checked in the Override column. This indicates that you’re
overriding the settings mentioned earlier, and it’s a good alert that things have changed from
the general Drawing Settings to this Object Level setting.
But what if you don’t want to allow those changes? Each Settings dialog includes one more
column: Lock. At any level, you can lock a setting, graying it out for lower levels. This can
be handy for keeping users from changing settings at the lower level that perhaps should be
changed at a drawing level, such as sign or rounding methods.
Object Settings
If you click the Expand button next to the drawing name, you see the full array of objects that
Civil 3D uses to build its design model. Each of these has special features unique to the object
being described, but there are some common features as well. Additionally, the General collection
contains settings and styles that are applied to various objects across the entire product.
The General collection serves as the catchall for styles that apply to multiple objects and
for settings that apply to no objects. For instance, the Civil 3D General Note object doesn’t really
belong with the Surface or Pipe collections. It can be used to relate information about those objects,
but because it can also relate to something like “Don’t Dig Here!” it falls into the General category.
The General collection has three components (or branches):
