Overview of Map Tools

The Map 3D tools in Civil 3D provide direct access to design, GIS, and asset data, enabling better planning, design, and management of infrastructure projects.

o Access a broad variety of data

o Improve planning and decision making

o Better utilize CAD-trained workforce

Taking Advantage of Map‟s Analysis Tools

AutoCAD Map provides a geospatial environment that is a hybrid of drawing features and feature sources from Feature Data Object connections.

Both may be used for analysis

AutoCAD objects require a topological relationship

FDO feature layers can be analyzed natively without converting

Three types of topology

Point or Node

Line or Network

o Knows the nodes at each end. Nodes know which lines are connected.

Polygon

o Knows the lines, and so the points, that bound it. Lines are aware of right and left polygons

Each component of a network topology has a length, resistance, and direction

Network topology components, or links, are connected by nodes.

In order for drawing geometry to be used to define a network topology, the links must meet cleanly at the nodes, with no gaps or overlaps

“clean”

Key Points

Topologies are stored within a drawing as object data

Topologies must be loaded to be used

Network topologies contain information about length, direction, and resistance

Shortest path

Best Route

Flood Trace

The geometry used to define polygon topology must be extremely clean, with no gaps, overlaps, duplicates, or crossings. The cleanup tools in Map 3D are designed to ensure this

Polygons store their topological information in centroids. You can choose to have AutoCAD Map 3D create centroids, or use preexisting objects
