AutoCAD Map 3D 2009

 
Exercise 2: Examine the object data
 
 
 

The drawing layers in your DWG file will become the feature classes in the new schema. The properties for each feature class are determined by the object data properties in the drawing. Use the Properties palette to see the object data.

NoteThis exercise uses the DwgMap_09.dwg map file you opened in the previous exercise.

To view the object data fields

  1. In the map, zoom in close enough to see individual objects.
  2. Select one of the pink polylines in the map.
  3. Right-click the polyline and click Properties.
  4. Notice that the color for these polylines is BYLAYER. Check the lower area of the Design tab of the Properties palette to see the object data.

    The pink polylines represent parcels and have object data related to address, area, value, and so on.

    You may see different information, depending on which polyline you selected.

  5. Press Esc to deselect the polyline.
  6. Pan, if necessary, to see the red lines in the upper left-hand corner of the map.
  7. With the Properties palette still open, select a red line.

    The red line represents a waterline. Notice that the color for this line is not BYLAYER. Within the layer, color has been used to indicate a particular type of waterline. In this case it indicates size. Red waterlines are between 26 and 48 inches in diameter.

  8. Deselect the red line and pan to the lower right side of the drawing.
  9. Select a green line.

    The green line is also a waterline, but it is a different size. Green waterlines are between 13 and 24 inches in diameter. Blue waterlines are between 1 and 12 inches in diameter.

  10. Press Esc to ensure that no objects are selected.
