Creates a block volume based on working plane coordinates.
Working plane X coordinates of the block.
Working plane Y coordinates of the block.
Working plane Z coordinates of the block.
Defines a hexahedral volume based on the working plane. The block must have a spatial volume greater than zero (i.e., this volume primitive command cannot be used to create a degenerate volume as a means of creating an area.) The volume will be defined with eight keypoints, twelve lines, and six areas, with the top and bottom faces parallel to the working plane. See the BLC4 and BLC5 commands for alternate ways to create blocks.
