Label Point
A label point is the point used to insert text to describe the digitized object.
You can specify a label point for each object as you digitize.
Layer
Plan the layers you will use in your drawing. A layer is a logical grouping of
data, which simplifies organizing and viewing data. For more information,
look up "layers, creating" in the help index.
Each object that represents a different type of map data should go on a separate
layer. For example, a polyline representing a coastline could go on a layer
named COASTLINE, interstate highways on a layer named INTERSTATE, land
boundaries on a layer named LOTS.
If you have not established a scheme for layer names, you can create one using
the numeric feature-classification code found in some digital source data. For
example, major roads might be on a layer named "170-201". A better naming
convention combines names that suggest their function and a structure that
allows selection with wild cards and groups of layer names. For example, you
might decide that all topographic objects should go on layers beginning with
the letters TP. So you might put rivers on a layer named TP_RIVERS, and
contours on a layer named TP_CONTOURS. To freeze, thaw, lock, or unlock
all layers with topographic data, you use the expression TP*. For more
information on wild-card characters, look up "wild-card characters" in the
help index.
Block Name or Linetype
To represent nodes using blocks available in the current drawing, select a block
name or ACAD_POINT for the block name.
Choosing ACAD_POINT places a point object at each node position. For
information about changing the appearance of this point object, look up
DDPTYPE in the help index.
Wherever possible, use the linetypes supplied with AutoCAD Map 3D to
indicate different types of boundaries, road types, and waterways. Using
standard linetypes ensures consistency across maps and helps you keep track
of what you have digitized. Associate each linetype with a different layer.
Object Snap
Use object snap to tie nodes or segments to linear objects that are already in
place. For example, always use object snap to position junctions of pipes,
roads, or railways.
