#### 11.2.17 bdPyramid

• bdPyramid( <3Dpoint list>, <3Dpoint>, [options] )
• Description: defines the pyramid built from a <3Dpoint list> representing the base (supposed to be in a plane), and a <point3D> representing the tip. bdPyramid options are those of bdFacet, plus:
• hollow := < 0/1 >. Shows if the pyramid is hollow or not (1 by default).

If the option border is $1$, the macro bdLine is called, its options can then be used.
