Detailed Description

Constructor & Destructor Documentation

Block::Block	(	Model *	mod,
		const std::vector< point_t > &	pts,
		meters_t	zmin,
		meters_t	zmax,
		Color	color,
		bool	inherit_color,
		bool	wheel
	)

Block Constructor. A model's body is a list of these blocks. The point data is copied, so pts can safely be freed after constructing the block.

Create a new block. A model's body is a list of these blocks. The point data is copied, so pts can safely be freed after calling this.
