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—points, 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.
The graphic on the dialog box reflects the extrusion method you choose and how it is applied.
