+A cuboid block is simply a simple, cubic block that has been clipped (truncated) on one or more of its axes.  The result is a rectangular prism shape that otherwise has textures applied in the same way as a [simple, solid block](Defining-a-Simple-Block) would have done.
+
+To define a cuboid block, first add the "boxblock:" line to the [Model Definition file](Model-Definition-Files).  See [[Defining Cuboid Models]] for details.  An example of this is the model definition for the Wooden Pressure Plate (which requires clipping of all three axes):
+
+     boxblock:id=72,data=*,xmin=0.0625,xmax=0.9275,ymax=0.0625,zmin=0.0625,zmax=0.9275
+
+Next, the textures for the block are defined as they would be for a simple, solid block: simply use a "block:" line with texture references for each of the 6 standard faces.  See [[Defining a Simple Block]] for details on this.  The corresponding texture definition for the Wooden Pressure Plate example (above) is:
+
+     block:id=72,allfaces=0:planks_oak,stdrot=true,transparency=TRANSPARENT
+
+Note: Most blocks suitable for rendering as a cuboid block will require the *transparency* attribute to be set - to TRANSPARENT for blocks that don't block lighting to other blocks, or to SEMITRANSPARENT for blocks that do block light (like slabs or stair).
