You can extrude 2D features into 3D objects of different heights by using feature attributes as the extrusion height. Extrusion is a layer property setting for the feature layer and requires you have a base height already applied for the feature layer in order for extrusion to apply. By combining base heights and extrusion properties, you can create a more realistic 3D view, without ever requiring 3D features.
Extrusion only applies to basic geometry types - point, lines and polygons.
To apply extrusion in ArcScene using a feature attribute, do the following.
- Right-click the layer in the table of contents and click Properties.
- Click the Extrusion tab.
- Check the box to extrude the features in the layer.
- Click the Expression Builder
button.
- Double-click the attribute in the Fields list to populate the Expression box and click OK.
- Click the drop-down arrow to specify the extrusion method. You can choose from:
- adding to each feature's minimum height
- adding to each feature's maximum height
- adding to each feature's base height
- using it as a value feature's are extruded to
- Click OK.
Optionally, choose to apply any operators to the attribute value.
For example, if you have the height of each building floor as your
attribute field, and know how many floors tall the building is, you
can add a multiplyer to calculate building height.
The graphic on the dialog box reflects the extrusion method you choose and how it is applied.
