Add gages of sheets for duct sizes to a schedule in Revit MEP

In Revit, you can add gages of sheets for duct sizes to a schedule

  1. First you need to make a schedule

  2. Then go to your schedule and create a “Calculated Value” I name it Rect.Max.Size, as the following shown steps:

 

1

 

In the textbox next to Formula type this:

if(Width > Height, Width, Height)

 

Which means select the maximum value and drop into the column “Rect.Max.Size”

  1. Insert data at “SMACNAHVAC Duct Construction Standard Metal and Flexible 2ndEdition”

By creating a “Calculated Value” I name it GAGES OF SHEETS FOR DUCT SIZES, which will be as the following steps:

 

2

 

In the textbox next to Formula type this:

if(Rect.Max.Size < 1′ 1″, “Gauge 26″, if(and(Rect.Max.Size < 2′ 6″, Rect.Max.Size > 1′ 1”), “gauge 24″, if(and(Rect.Max.Size < 3′ 6″, Rect.Max.Size > 2′ 7”), “gauge 22″, if(and(Rect.Max.Size < 5′, Rect.Max.Size > 3′ 7”), “gauge 20″, if(and(Rect.Max.Size > 5′ 1”), “Gauge 18”, “NA”)))))

 

Which means select the maximum value and drop into the column “Rect.Max.Size”

 

The schedule will be as this:

 

34

 

 

A comment below by Engr. Sameh too important to consider, as he said, there’s a new tables should be taken, that’s why you can take above steps and practice using the new tables.

I am a mechanical engineer, I worked at many disciplines: drawing, testing and balancing for heating, ventilation, and air conditioning systems, maintenance of multiple different mechanical equipment. I'd like sharing knowledge with others and create an easy tutorials to understand. I hope all people can get knowledge, and all CHILDREN have a good caring and peaceful place for living.

    1. Copy and past the following formula
      if(Rect.Max.Size < 13", "Gauge 26", if(and(Rect.Max.Size 13″), “gauge 24″, if(and(Rect.Max.Size 31”), “gauge 22″, if(and(Rect.Max.Size 43”), “gauge 20″, if(and(Rect.Max.Size > 61”), “Gauge 18”, “NA”)))))

    1. This as put in a Revit, Copy and past this
      if(Rect.Max.Size < 13", "Gauge 26", if(and(Rect.Max.Size 13″), “gauge 24″, if(and(Rect.Max.Size 31”), “gauge 22″, if(and(Rect.Max.Size 43”), “gauge 20″, if(and(Rect.Max.Size > 61”), “Gauge 18”, “NA”)))))

  5. Please note that as per SMACNA 3rd edition, the up tables has been declined, you should follow up the SMACNA table 1-3 thru 1-9. and you should investigate whether your duct is reinforced or not, giving this method described above, will make untrue estimation for duct construction, which eventually shall cause losses in money.
