The default shoebox model generates a building with two separate structures

Detailed Description

Running the "Create Bar From Space Type Ratios" measure with default arguments creates two separate building structures. Even though the measure states "Creates one or more rectangular building elements based on space type ratios of selected mix of building types, along with user arguments that describe the desired geometry characteristics.", this is probably unexpected for most users.

Possible Implementation

Determine the cause and update measure arguments to generate expected results.
