ISO/TS 10303-1404:2018-11 specifies the application module for
Geometric model 2d 3D relationship.

The following is within the scope of
ISO/TS 10303-1404:2018-11:

• This part of ISO 10303 specifies an application module for the
  representation of the information needed to describe a geometric relationship between a geometric model in a two dimensional
  coordinate
  system and a corresponding model in a three dimensional coordinate system where the relationship is for coordination purposes
  and not
  for definitional or placement purposes.
