Review: Dummy Material

Joist panels are entirely composed of dummy material. Joist connection materials are regular plates or angles, and joist bolts are just regular field bolts.
If you use Manage Reference Models in Modeling to import an DGN, DWF, DWG or IFC reference model, the reference model will consist of a single reference model member to which there may be attached one or more dummy materials.
A dummy material is assigned a submaterial mark prefix of d. In other words, dummy materials are assigned piecemarks such as d1, d2, d3, etc.
Dummy material is not included in reports (such as the Joist Report or Connection Calculations or Expanded Connection Design Calculations ), and it is not listed in any member's bill of material .
Dummy material does appear on member details, but is not automatically included in the member bill of material and is not called out or dimensioned on a member detail or submaterial detail.
