Hey we have some exciting news! We are partnering up with MEP Guy to launch the most effective REVIT courses for MEP designers and engineers! Check out the Electrical course preview and sign up here: www.mepguy.com/electrical As a special bonus, we're offering a free download of an Electrical Clearance family that anyone can use to designate a "no fly" zone or clearance zone that must be maintained in front of electrical equipment. Drop it anywhere you need folks to keep clear of zappy things!
So for one of my projects, I had to create cross sections of the cable tray and designated each cable’s source and load by using a legend. It was super tedious but it was the only way to see each cable in the tray and indicate spacing, dividers or waterfalls. We did not have to actually model each cable as I think the only way is to show conduit and pretend it’s cable. I only did that once for medium voltage cables that were about 3.5” in diameter.
The cross sections were drawing with detail lines inside the cable tray so I had to make sure the sections were pinned in place. We had signal cables, 120/208v power and 480v on a single tray with dividers. It was too much to model so we drew it to scale using detail lines.
I could send you the file iam working on it, its a LV room for a building and there are a lot of tray and cables, I am desperately need any recommendations to make the section and filling ratio with revit. Just type your mail to send it
I enjoyed your quick tips in this video. I like to use hot keys (come from autocad). Are you using hotkeys? If so, do you know where I can find them and or customize them? Newer to Revit. Thanks!
I get made fun of during clash detection sessions until I explain why. Then the room gets quiet and there’s always the one piping guy that goes “so I can pass through your cable tray then?” 😐 no stay OUT of my tray space!!!! 🤦🏻♂️
Hello and thank you for this very good exlanation. Just a question: why do you make the cable tray thiker if you can add 6 inches as clearance in the familie? Is it because revit can not detect clashes with clearance? Thanks again
Our cable tray family does not let us add clearance space. If you found a way to do so, that would be great info to have! My workaround has been to make the tray thicker to include the clearance in its dimension.
Usually around hallways, but the last 20-30 feet to the outlet in each room is typically done using J-hooks or some type of hanger. It’s usually because trying to get a straight shot of cable tray into the room is tough due to ductwork and piping being in the way. Most j hooked can hold about 30 or so cables so it’s sufficient to serve the room with just hooks.
Thank you for the information. Is there a way that you can do auto cable tray if you click one tray then click another cable tray that are seperated by a certain distance and they would connect automatically avoiding clashes. Is there a plug in for Revit
That would be an amazing feature or plug in! I don’t know of any such product that would do that. I know from a distance you can Trim to connect to ends of conduit or cable tray but it will make a straight run without any consideration to what’s in the middle.
Sometimes the template that the project is created from does not have cable tray loaded. I guess I should start a family download center of the stuff I talk about
@@theelectricaldepartment No, Actually running the entire route in vertical. Do I then resort to rather using a manipulated Ducting tool? Thanks for the reply. :)
Oh yes you can certainly match the slope of the roof. If you draw in section view, you’ll find that you can create any angle in your bends provided you leave enough space for a fitting to be auto generated.
taught my brother-in-law in roughly...2 months. From no experience to an excellent level 1 Designer. To this day, he earns more than an entry engineer.
@@theelectricaldepartment yes... both of them... can we model only cable at cable tray, without conduit... is it posible..? Is the software allow us to do that..,? In real life, some time we just laying the cable without conduit... i am not talking about the code, just wondering if it is can be done.... thanks for answering my question...
No Revit does not model wires or cables. The wires you see on floor plans are just annotation and that’s the best we get. If we want to show fill capacity we simply show a detail section drawn in a drafting view. For large multi conductor cables I have shown conduit in the cable tray to simulate cables.
Americans will not have good quality engineering until they start using metric system... feet, inches, fractions, etc., are very inaccurate, and when using them on material length, the error is accumulated massively. Meter is a NATURAL, consistent and absolute unit... is coming from 100cm... and 1 cm is the diameter of a drop of water... Egyptians were using it... also the Royal Cubic of the Egyptians comes from Meter/Centimeter... then relationship between cubic meter to water weight/kgr... etc Setting AutoCAD or Revit in millimeters means that every unit of error if any, would be a millimeter, and not an Inch (25.4 mm)...

Thank you, Sir, you are a gentleman and a scholar.
I really love that TAP trick when you select all CT Raceway together, Thanks
how can i annotate the cables the run inside cable tray ? could you plz help me, I'll be grateful

Thank you so much for your great work. I am a beginner of the Revit and need to learn to use the software.
Glad it helps! Post any questions you have, I get most of my video ideas from my viewers!

Love the idea of making it higher for space under the duck !

should i draw my cable trays around my hallways and into the respective rooms?

good work& good information
make some tutorial on lightning protection grounding strip 50x6 parametric with clip fixing on rooftop
Very informative ... thanks!
Hello, i have created a construction template project......when i choose cable tray from sysytems, i have no option to pick ladder rack??
Great video
Hi Dear I need all Revit MEP toturial my practice..
Can u send me all link.. Because I need my project creation..
Great work
Hi, Can you tell why there was no cable ladder loaded in my revit model. How can I load that? where I can get cable ladder into model?
Sometimes the template that the project is created from does not have cable tray loaded. I guess I should start a family download center of the stuff I talk about
How do you do cable trays in a vertical configuration for clients who do not allow horizontal in their spec's?
Like a vertical riser or a vertical lateral?
@@theelectricaldepartment No, Actually running the entire route in vertical. Do I then resort to rather using a manipulated Ducting tool?
Thanks for the reply. :)
I just had a thought to make a video where I run a cable tray on all 6 surfaces of a room 😆 that should cover all orientations! Hahah
What about sloping cable trays? Possible or not? long runs under roof equates to several 90 degree bends to the desired location... Super odd
Oh yes you can certainly match the slope of the roof. If you draw in section view, you’ll find that you can create any angle in your bends provided you leave enough space for a fitting to be auto generated.
How long does it take before you become proficient with this program?

can we put cabling route in cable tray, which is connected to lamps, switch, etc..?
Are you asking if we can model that or if you are allowed by code to put cables in there?
@@theelectricaldepartment yes... both of them... can we model only cable at cable tray, without conduit... is it posible..? Is the software allow us to do that..,?

Please could you do powerskirting
oh yea that sounds like a good one! We are switching some mobile casework to fixed on my project and I'll need to run them on the workbench soon.
Do u have any video to create electrical duct bank that can give length?
I’ll make one just for you 😉
New video is up for how I determine my duct bank lengths.
@@theelectricaldepartment thank you
Thank you!
Do you know how to create cable tray cover
Sorry, no, I do not! Do you need to show it to be graphically accurate or is it for some other reason?
@@theelectricaldepartment graphical reperesentation
thx
