MEP Drafting Projects Course

Master AutoCAD, the industry standard CAD tool for AEC, covering 2D and 3D drafting, design visualization, and essential installation steps.

Master basic AutoCAD tools for hvac drafting, including lines, polylines, circles, arcs, blocks, hatch, dimensions, text, layers, modify, scale, units, and plotting for ducts, vents, and equipment.

Learn to create and edit hvac drawings in AutoCAD by setting up units and scale, drawing components, inserting blocks, adding dimensioning, organizing layers, hatching, and preparing documented outputs.

Explore common hvac drawing symbols, including ductwork, equipment, piping, and control symbols, to read hvac drawings and identify diffusers, dampers, vav boxes, valves, sensors, and bms.

Convert architectural plans to gray for hvac drafting by purging unwanted objects, applying a gray layer palette, and turning each floor into blocks to streamline service setup.

Apply the thumb rule to estimate heat load and supply cfm for hotel spaces, using tr = area times 0.07 and 1 tr = 400 cfm, including dining and ballroom.

Size air terminal devices for spaces by calculating CFM and selecting diffusers, grills, or registers. Use Gulf Grill Corporation catalog and Beta Industrial software to determine size and placement.

Learn to place air terminal diffusers and return diffusers across ballroom, dining, conference, and bedrooms, using diffuser sizing from catalogs and beta software, and applying AutoCAD offsets and distances.

Plan and place mechanical equipment by room, selecting ahu and fcus, chillers, cooling towers, and pumps based on cooling capacity and airflow; coordinate ducting and above the false ceiling.

Learn to draw a single line ducting layout for ground floor projects, create and manage duct layers, place supply and return ducts, and prepare for double line diagrams.

Size ducts with Mcquay duct sizer using equal friction and 0.08 in water per 100 ft loss to distribute 3800 cfm across corridor and dining areas with duct aspect ratios.

Master the double line ducting layout and shop drawing, from rectangular duct sizing and offsets to reducers, elbows, concentric and eccentric fittings, and flexible duct connectors.

Design fresh air ducting layouts and size them using the 10–15% fresh air rule and CFM calculations, then implement risers, volume control dampers, and FCUs in AutoCAD.

Apply 25 mm insulation to supply, return, and fresh air ducts within the ducting layout, using an insulation layer, color coding, and offset and trim techniques.

Place hangers and volume control dampers (vcd) on every branch of the ground floor, create a layer named volume control damper vcd, and maintain maximum hanger spacing of 1800 millimeters.

Learn to draft a single-line chilled water piping layout, create chilled water and cold water headers, and connect pumps, expansion tanks, FCUs across floors using piping and drafting tools.

Learn how to size chilled water pipes using a closed-loop and open-loop system, convert TR to GPM, calculate FCU flow, and select pipe sizes with the Macweb pipe sizer.

Master double line chilled water piping layout by sizing, offsetting, and placing T fittings and reducers, and aligning branch and main pipes with correct diameters.

master section drawing for hvac on a ground floor using AutoCAD: place section callouts, configure viewports, draw room geometry, hatch concrete, and outline duct layout with reducers and diffusers.
