4.7 FNDBLOCK
Foundation blocks are materials within the two-dimensional domain beyond those defined by the slab and wall SURFACEs. Each block is represented as a rectangle in the domain by specifying the X (lateral) and Z (vertical) coordinates of two opposite corners. The coordinate system for each point is relative to the X and Z references defined by the user. As a convention The positive X direction is away from the building, and the positive Z direction is down.
Options for X and Z references are illustrated in the figure below.
The default reference is WALLINT, WALLTOP.
An example of defining a block for interior wall insulation is shown below. Here the two points defining the block (P1 and P2) are both shown relative to their reference points (Ref1 and Ref2, respectively).
Note: X and Z point values of zero imply that a point is the same as the reference point. The default for X and Z point values is zero since points will often align with one or both of the reference values.
It does not matter which of the four corners of a block are used to define the two points as long as they are opposite corners.
