Usually there is not enough time & money budgeted on the job to do 3D design for commercial HVAC work. Design drawings are typically specified to be considered as diagramatic & it is up to the contractor doing the installation, to prepare shop drawings & coordinate installation & clearances with all trades. The designers though must provide enough space for installation & servicing. They should block out typical service access space for equipment.
The 3D drawings therefore can be more useful to the installing contractor to help them prepare coordinated as built drawings.
