Enable Cable Tray to accumulate wires (like ducts do with CFM)

[dtiemeyer]

Would love to have cable tray be able to accumulate quantity of wires (thinking of Cat5/6 wires specifically). Perhaps enable 'analytical connectors' so that if I create a family that has a data connector, it could be 'analytically connected' to the cable tray that the wire will run in, then as the cable tray gets closer to the IT closet, it would have a higher number of wires. Perhaps also add the ability to include a quantity of more than one data connector in a family (like a power pole that could serve 6, 8, or 10 cubicles, user just types in that qty of data cables).

Dear Autodesk Revit team,

Presently, all released Revit MEP software versions doesn't have a capable of perform the electrical cable tray sizing calculations.

This task is very important in complex projects such as Metro Rail, Airport, Hospital, Mixed used buildings etc..

As of now, cable tray sizing calculations are doing in excel spread sheet and sizes are modelling in Revit software with coordination of other services/elements. I strongly saying that, this is more complicated process in electrical design and vital role with respective design and ceiling void space in such a complexity project.

To overcome this issue, I have developed a simple practice method and excel spread sheet tool, which i have used in different projects and job done very well with accuracy. So that, i would like to share my concept and idea with Autodesk team to implement in Revit MEP product and this will be much more helpful for Revit MEP user in worldwide. 

Below steps to be followed to calculate. 

Step 1: Assign an unique cable tag for feeders which are laying from one place to another place in cable tray

Step 2: Mark the cable tray routing path with an unique tags 

Step 3: Select the feeders travelling path with respective step 2. This step should complete for all feeders.

Step 4: calculate the no of cable in a cable tray path and calculate the cable tray size. If cable tray size increases more than available size in market, then change to multiple cable tier.

Step 5: Adjust the multiple cable tier cables

Now, Autodesk Revit MEP team to develop a program based on above steps.

However, I am ready to demonstrate the procedure, sequence and other items based on our further future discussion and meeting if your team contacts me. You can contact me on my email ID: [email protected] for further queries.

I hope you have understood the concept and logic to develop the program.

Thanks

I voted your idea and a proper cable tray sizing tool is my dream. We are using the same method for cable tray sizing and it seems that we are doing the same job (electrical installation design of metros).

But I have no hope from Autodesk, because electrical part of Revit MEP is nowhere near to European or International (EN/IEC) electrical design practices.

Hi,

We have just released our Automatic Cable Tray Sizing Add in for Revit - AutoCT!

It can automatically route circuits within the Revit model and assign them to cable trays or ladders.

It can also work for unconnected cable tray networks and we've recently added a feature to import/ export cable sizes from Excel.
