Component Grade 0 (G0) – Schematic
• Symbolic place-holder representing an object which may not be to scale or have
any dimensional values.
This is particularly relevant to electrical symbols which may never exist as a 3D
object.
Component Grade 1 (G1) – Concept
• Simple place-holder with absolute minimum level detail to be identifiable, e.g. as
any type of chair.
• Superficial dimensional representation.
• Created from consistent material: either ‘Concept–White’ or ‘Concept–Glazing’.
Component Grade 2 (G2) – Defined
• Contains relevant metadata and technical information, and is sufficiently modelled
to identify type and component materials.
• Typically contains level of 2D detail suitable for the “preferred” scale.
• Sufficient for most projects.
Component Grade 3 (G3) – Rendered
• Identical to the Grade 2 version if scheduled or interrogated by annotation. Differs
only in 3D representation.
