| |RI 300 | Signals reused geometries | Signal parts geometries shall be mapped (IfcMappedItem) to their matching type geometry | Every signal sharing the same type shall reuse shared geometry defined for the signal type| | ||
| |RI 301 | Signals as assemblies| Signals shall be modeled as an IfcElementAssembly with aggregated post, foundation, mast and signal port| Signal posts shall use parametric/lighweight geometry and avoid heavy tessalated or BRep geometry | | ||
| |RI 302 | Signals reused types| Signal parts shall be using IfcElementAssemblyType entities| Signals shall be defined by their type with their characteristics | | ||
| |RI 304 | Stationing address | IfcReferents (typed POSITION or STATION) linked to IfcAlignments need a IfcRelPositions relationship | A Linear address shall be known from the alignment it relates to | |
There was a problem hiding this comment.
What is preventing the business requirement to be answered via the nesting relationship between an alignment and its referents?
Also, the current IFC documentation does not specify how and when to use IfcRelPositions between an alignment and referents.
Please clarify the requirement or put forward a proposal to modify the current IFC documentation.
