Default Geometry
Specifies the geometry and alignment of the object. The geometry of an object
depends on its number of faces and alignment. A single-face view-aligned
object appears in the drawing as a triangle. You cannot use grips to rotate it.
A single-face fixed object appears as a rectangle that you can rotate with grips.
This type of object also displays its name either forward or backward to indicate
its orientation to the camera, which is helpful for signs. A crossing-face object
always appears as two triangles intersecting at right angles. When view-aligned,
they face the camera at 45-degree angles and you can’t change their rotation.
When the object is fixed, you can change its rotation.
Single Face/Crossing Faces
Specifies a single-face object or a crossing-face object. A single-face object
is faster to render but not quite as realistic as a crossing-face object, especially
for animation and raytraced shadows.
View Aligned
Makes the object always face the camera. This is generally a good choice
for trees and other nonplanar objects.
When the View Aligned option is cleared, the object maintains a fixed
orientation. This can be effective with planar objects like road signs that
you don’t want to view straight on.
Name
Shows the current name of the object. To change the name, edit the entry.
