Online Event:  ABD SIG: Creating the Mechanical Model

Live Q&A Webinar:  Tuesday, December 23rd at 8:00 AM PST or 4:00 PM PST

Description: AECOsim Building Designer is a single building information modeling (BIM) software application for multi-discipline teams. It enables architects, structural, mechanical, and electrical engineers to design, analyze, construct, document, and visualize buildings of any size, form, and complexity.  AECOsim Building Designer includes capabilities of former products: Bentley Architecture, Bentley Mechanical, Bentley Electrical, and Structural Modeler.

   For our second ABD SIG topic, Creating the Mechanical Model, we will cover the essential aspects to using ABD to create the mechanical model.

   To get maximum benefit from this Special Interest Group “flipped classroom” meeting, registrants will be assigned to watch some free videos introducing the different components of ABD.  Questions can then be posted on Be Communities.  The webinar itself will briefly go over the assigned videos, and then will answer any questions that have been posted or asked during the webinar.

  • A question was asked in the morning session about changing the height and width of an AHU because in the DataGroup Instance dialog there's only a field for Total Length.

    There are two ways to place an AHU:
    One way is to use one of the standard AHU tools under the HVAC Equipment task. This way allows you to define the Total Length of the AHU and then it derives the other dimensions from the Cell that gets placed. You could open up the cell library that these cells exist in and edit the proportions of your cell there to adjust how tall or wide the AHU will be for a given length.

    The second way is to use the Place Content tool and choose AHU_Schematic for the Instance Data Type (icon that looks like a hierarchy tree) in the dialog. This will allow you to define all of the properties for that piece of equipment.

  • What about Round AHUs (AHU 1 and 2 tools), there is no cell to fall back to (compound cell but no name)... We are tryin to change the default (piece of pipe) to a Revit-imported RFA that includes a fan etc. Any idea?
  • Chris, can you elaborate on what you need to do? Danny's last post outlined an alternate method when only Length was available during placement, but Round AHU's have Length and Diameter (effectively height+width).



  • Steve,

    There are 2 icons for Round AHUs - AHU1 and 2.  Both place the same (or what appear to be the same) compound cell. What I would like to know is:

    Can I change the default compound cell associated with those tools? (basically understand how those tools work, there is no name to the compound cell and therefore hard to figure out...)

    If yes, I have imported via the RFA wizard a real AHU with a lot more detail like fans etc. Can this be used to replace the (pretty basic) default...

  • Ah... I see. I'm no VB guy, but after a quick scan through the code for these two tools I get the feeling that there may be no cell associated with them, but rather the geometry (simply a Cone) may be generated on-the-fly.

    Have you tried using the RFA Wizard to import your RFA file as an AHU? Not that I've ever tried, but it seems like something that may/should be doable. I think.
