For CT cans we create a CT gutter bus with 2 taps in addition to the meter gutter bus above. The first tap goes to the load and the second tap goes to the meter. We then play with the one line to show a feed going through and a tap to the meter. Not perfect, but it works.

The hanger problem you are having is a bug. I have sent you a patch for this error directly.

I have been playing around with the newer BIM features. We (co-workers) are excited by what we see so far. I am still trying to figure out the alignment point and it’s purpose. One problem I just encountered is with cable tray on a second floor. I’m operating on the assumption that the alignment point for my second floor DM plan should be set at the floor elevation of the second floor (In my case 14′-8″). First of all, is that a correct assumption? The settings in the cable tray dialog box would then be the same as they were for the first floor. After creating the IFC, saving as RVT, and inserting into Revit model, the cable tray appeared at the correct elevation on the second floor, but the trapeze hangers remained at the first floor cable tray elevation. Has anyone else experience this that you know of? Can you imagine what I might be doing wrong?

In DM, the 0,0 point for your model is the alignment point. The north arrow points toward angle 0.

In Revit, there is a survey base point and project base point. You can see the location for these using the “Reveal Hidden Elements” button next to the horizontal scroll bar at the bottom of the screen.

You need to make sure the DM alignment point and Revit base point are set to the same location.

We can calculate flow for any type of pipe, but we do not yet size it automatically:

This tutorial failed to mention the insertion of Room # into a circuit description (Editor’s Note: Good catch! We added this missing information).

Thanks. Keep up the good work.
