HVAC Drafting

HVAC Drafting Samples

Representative 3D HVAC base models are shown below. Please click on them for larger images

Equipments drafted include air conditioners, AHUs, ventilators, blowers, duct noise filters, duct dampers, duct reducers, duct attenuators, duct fire valves and water piping with accessories.

Advantages

• $11 per hour instead of $35 per hour for drafting work
• Work supervised by experienced engineers
• Pay-per-use only: no minimum monthly fee!

Inputs Required From You

• HVAC schematic

• Preferred position of equipments if any

• Preferred size and location of wall, floor and ceiling openings if any

• Location of external mating ductwork and pipework

• Specific guidelines for clearances and physical layering, if any

• Manufacturers' data sheets for machinery (with dimensions)

• Duct and pipe selection charts with boundary curves

• 3D HVAC symbol library (if specific symbols required)

• License for preferred 3D HVAC design application (other than AutoCAD)

• Sample output files

What We Will Do for You

• Refer to the HVAC equipment data sheets you provided and create non-detailed, scaled 3D block objects of each one

• Based on airflow figures in the schematic you provided, select each duct’s shape and cross-sectional area

• Place the equipment blocks in accordance with your preferred position diagram

• Route ducts and water pipes according to the schematic you provided (also considering access to each part of the room) following the guidelines for clearances and layering you provided

• Add accessories to the ducts and pipes

• Generate a scale 3D model of the completely fitted out HVAC room

• Generate 2D sectional installation drawings with annotations and dimensions for installers to use on site
