Pointers from the Design DB and Specification

The Specification Component (SPCOM) has attributes MATR and FLUR. These are material reference and fluid reference, which point to the pipe material (SOLI) and the fluid within the pipe (FLUI), respectively.

In the Design DB, Pipes and Branches also have these attributes MATR and FLUR. If these are set, the references from the Specification Component are ignored, but if they are unset, the references from the Specification Component are used.
