See 13.6.7.3.2, \"3D linear dimension measurement\" for a listing of additional entries in this dictionary.\nPD3 A perpendicular dimension measurement is used to denote the perpendicular distance between two geometric entities (normally two lines or a point and a line). See \"Table 328 — Additional entries in a 3D measurement/markup dictionary for a 3D perpendicular dimension measurement\" for a listing of additional entries in this dictionary.\nAD3 An angular dimension measurement is used to denote the angle between two linear entities. See \"Table 329 — Additional entries in a 3D measurement/markup dictionary for a 3D angular dimension measurement\" for a listing of additional entries in this dictionary.\nRD3 A radial dimension measurement is used to define the radius or diameter of a circular 3D entity. See \"Table 330 — Additional entries in a 3D measurement/markup dictionary for a 3D radial dimension measurement\" for a listing of additional entries in this dictionary.\n3DC A 3D comment note lets users connect a comment to a specific piece of geometry in the 3D model. See \"Table 331 — Additional entries in a 3D measurement/markup dictionary for a 3D comment note\" for a listing of additional entries in this dictionary."
