HVAC Duct Fabrication drawings

[Ramana]

Hi Friends,

 

Greetings of the day!

 

Can any one guide me how to develop the Fabrication drawings for Duct works using Revit, We are working on an US project, the client is expecting the Sheet Fabrication Drawings for the duct system. If any one have some sample drawings for the same, please share for the reference. 

 

 Till now we have worked only developing the layouts.

 

Thanks in advance for the support

Are you using Autodesk Fabrication within Revit? And if so have you set up the fabrication database to meet the spec of the duct contractor's sheet metal shop with their duct tables? For true fabrication level detailing this would be a bare minimum requirement for takeoff purposes. 

 

Native Revit Families for the duct systems doesn't have things like duct joints or TDC/DM flanges, etc so it's hard to create true sheet metal fabrication drawings for a duct manufacturer to do a takeoff from. You'll need to consider using Fabrication within Revit. Also, the area of sheet metal fabrication drawings requires some added knowledge in SMACNA standards for things like offsets, transitions, duct joint lengths, material types and many other things. The way you're asking your questions leads me to believe you have very little experience in this and that may be something to consider with your customer in the US. 

 

The attached screenshot is from a project of ours that shows what FabParts in Revit looks like on a shop drawing deliverable for a sheet metal fabricator. Lots of information is needed and knowledge of the duct manufacturer's specs is a must.
