Flexible conduits

Here in Australia we are modelling more and more 'sweeping bends' conduits, mainly due to the new NBN (National Broadband Network)

Revit does not allow us to draw a conduit with a radius in one go, we have to attach bends etc, this does not work in this scenario, we need to have one element but this is not possible without drawing an 'in place' family each time, which is totally unviable due to time constraints/changes.

Surely it would not be too hard to draw a conduit from point 'A' to point 'B' as you would a spline in CAD?

Thanks for the suggestion.

 

Can you elaborate what actually is meant by a flexible conduit?  E.g., a reference to a manufacturer's product, link to PDF, or other relevant catalog information.

Contributor

Please refer to my original post, it is all the same conduit as we always use, mainly 23mm OD in the NBN installations, but instead of a rigid configuration of the conduits using bends, elbows etc, it basically goes from A to B as the crow flies but with a 'flexible' path, the installers here actually call them 'sweeping bends' as the conduits will NEVER be installed in a straight line.

My problem in revit is that when I want draw a conduit from point A to point B, if using the path that the conduits will be installed to, revit will produce loads of minor bends, which then screws up my scheduling, therefore the only way to draw it properly, is to do an in place family, but on tower block installations etc, this will be hundreds of conduits, which makes it impossible to do, therefore we have to cheat to get the end product as revit makes un-feasible to do!

Martin we specify Anaconda Metallic Flex conduits for use in Electrical pits from conduits to Cable trays here is the link to give you an idea

http://www.anamet.nl/products/anaconda-flexible-conduits-and-fittings/

 

They work very similar to the flex pipework for sprinklers so i would assume you could use the same technique where you connect to the end of the conduit and run from there they would just require different fitting types.

Martin,

If I think the addition of a Flexible Conduit function is becoming more critical for Revit. In Australia we use a lot of what is called flexible conduit, in transport and commercial street lighting and services.

Link to flexible corrugated PVC http://www.clipsal.com/Trade/Products/Catalogue?c=1&ms=5&s=14&mg=385

 

I think having a Flexible Conduit function essentially the same as the Flexible Duct or Pipe in Revit, except with conduit connectors is essential to proper electrical modelling.

 

I have not seen any mention of this in 2018. Is this something in the works?

All the electrical designers need a flexible conduit, liquid tight, etc., conduits that can be quantified, scheduled a so on in Revit.

@grahamlyon1977

I totally agree with you. This is a must-have for electrical installation.

 

@martin.schmid

You could probably use Flex Duct from HVAC as a template for the flex conduits.

That´s pretty much how they should work.

Autodesk
Autodesk

I think what is being described here may be two separate things... 

 

1. flexible corrugated PVC - which may be similar in concept to Flex Duct/Flex Pipe in Revit.  Have you used flex duct / pipe to model conduit presently?  Does it provide you with the control and capability that you need from a geometry perspective, or does it leave anything to be desired?  The reason I ask is that we've had requests for folks that have attempted to route PEX piping, and have struggled, as the functionality was designed for flexible connections at equipment more so than routing long distances, and on multiple planes. 

 

2.  in the original post indicated "all the same conduit as we always use" and "allow us to draw a conduit with a radius".   what I interpret that to mean, and along with the provided image, is that he is looking to have rigid conduit that allows bending to conform to a large diameter radius. 

Contributor

@Martin__Schmid

What I was originally asking for which may be a little lost in my initial explanation was the functionality in Revit MEP to model an electrical conduit the way you would model a flex duct in mechanical services.

I need to model a conduit at the normal diameters (23mm, 50mm, 100mm OD) from Point 'A' to Point 'B' like we would draw a spline in AutoCAD. it needs to snake around corners etc and be on the system category of electrical conduits.

Why would we model it as duct/pipe? it's an electrical fixture.

This is a major problem in Revit MEP to just have the function to model 'rigid' conduit, the practical application for this is not like this anymore.

My initial post has a screenshot of a drawing from AutoCAD, if we could replicate this function Revit MEP and have as a 3D element, this would make mine and many others lives easier!

Autodesk
Autodesk

@grahamlyon1977 - thanks for the clarification.

 

to address your question, "Why would we model it as duct/pipe? ":

 

This was was really more directed toward @dominikleuchter 's suggestion that "could probably use Flex Duct from HVAC as a template for the flex conduits"...

 

My inquiry in the prior thread seeing if this was truly the case... as I stated:

 

Does it provide you with the control and capability that you need from a geometry perspective, or does it leave anything to be desired?  The reason I ask is that we've had requests for folks that have attempted to route PEX piping (like this and this), using flex piping, which is basically the same editor as Flex Duct... and they have struggled, as the functionality was designed for flexible connections at equipment more so than routing long distances, and on multiple planes. 

Contributor
Contributor

Sorry for creating confusion here. I may have expressed myself wrongly.

 

Basically i meant it as g.lyon wrote it. A flexible conduit as additional family and not a Flex Duct/Pipe replica or something.

What I actually wanted to say was that it should have the flexibility of Flex Duct / Pipe.

I have not used Flex Duct / Pipe in detail yet but I got the idea from trying out several standard Revit Familys to see if there is one with similar to the flex conduit we need.

 

Sorry everybody. Emoticono feliz

Thx for clarifying @dominikleuchter - my question still stands... I'd still be curious about the ability to model w/ flex pipe/duct... if you had the exact same geometric functionality to model flex conduit... what works well about it?  what doesn't work well?  If you have chance to give it a try, it would be interesting to get that feedback.

It leaves Six things undesirable:
-Past job we uploaded our Revit model to the General Contractor for clash detection. Forcing us to use "flex duct" as an electrical device sometimes plays havoc on the coordinators clash files because they will inadvertently use system filters to separate and export Trade designated coordination models into Navis for clash detection. Since Flex duct is not an electrical system, it ended up in the Mechanical contractors NAVIS clash file. This was a Lesson learned. The solution was to use a "work around".
-Primary and secondary panels with a transformer in-between them we have to use a conduit elbow for GTP then filter out off for coordination upload, we use the flex duct as the flex connection because in actually can fit more like the field install. If this was an electrical system GTP would probably update their program to "connect" these on the autonomous one-line.
-Creating a BOM for Flex/Liquid Tight we have to add an extra step to the schedule so its description is correct.
-Have to customize fittings with conduit and flex duct connectors on each end.
-For BOM reasons-cannot get an accurate Run length to calculate wire lengths. The flex or liquid tight does not get captured in the total length of the run. We have to manually add length, (this is AKA a "workaround").
-GTP does not automatically recognize Flex Duct at final equipment connection, have to use a manual "work around" (use conduit that will be filtered off on Coordination model export) as opposed to the program autonomously adding the P.O.C. intelligence.

The electrical "Flex" family needs all the descriptions from the NEC (National Electrical Code-North American).
Here are a few examples:
-Flexible metallic Conduit (MC) i.e. aluminum or steel
-Liquid tight Flexible Metallic Conduit (LFMC) i.e. Steel, Aluminum
-Liquid tight Flexible Nonmetallic Conduit (LNFC) i.e. PVC

The Cable and Wire Family needs all the descriptions from the NEC (National Electrical Code-North American).
Cable and wire would have absolutely created value for my department on our last job for BOM purposes. Using conduit as cables in tray was very cumbersome, modifying conduit would inadvertently delete or move sections of tray furthermore the bending radius of wire is smaller than what Revit would allow for the conduit.

-Cable i.e. Triplex, TC or other types, Sometimes cabling can have a 3.5" O.D on these.
-Wire i.e. THHN 500 mcm Cu.
Please try to push this product improvement especially when this has been posted for over 3 years.

 Hi @Kevin_Laskowski - thanks for those details, very helpful to understand the scope of the problem... I am still curious, from a geometric perspective, if the way that the flex duct/pipe geometry itself behaves, have you run into any particular challenges when using it to geometrically represent flex conduit... or if it works perfectly well... e.g., if the same geometry/modelling interactions were applied to a flex conduit element, would you be happy, or would you say, "when I'm trying to do certain things to get the flex to route a certain way, or be at a certain elevation, or go through a particular point it doesn't do what I want."

It works extremely well . Possible attribute to add would be minimum allowable bending radius based on type and diameter.

 

 An example for Armored Cable (AC) would be NEC 320.24 Bending Radius.  The radius of the curve of the inner edge of any bend shall not be less than five times the diameter of the Type AC cable.

 

 An example for metallic Clad Cable Cable (MC) . The radius of the curve of the inner edge of any bend shall not be less than required in 330.24(A) through (C).
(A) Smooth Sheath.
 (1) Ten times the external diameter of the metallic sheath for
cable not more than 19 mm (3⁄4 in.) in external diameter
 (2) Twelve times the external diameter of the metallic sheath
for cable more than 19 mm (3⁄4 in.) but not more than
38 mm (11⁄2 in.) in external diameter
 (3) Fifteen times the external diameter of the metallic sheath
for cable more than 38 mm (11⁄2 in.) in external diameter

Hi @martin.schmid

I did some testing with the Flex pipes to answer your question about the "geometric perspective" you asked for.

 

@Martin__Schmid  wrote
... I am still curious, from a geometric perspective, if the way that the flex duct/pipe geometry itself behaves, ...

Here my opinion on what works well with Flex Pipe and what doesn´t:

 

- Basically the way Flex Pipe can be placed / drawn works as we need it. Especially, the possibility to adjust it afterwards (through "vertex" and "tangent" points). That's the kind of flexibility a flex conduit should have.

- What is missing is the possibility to place it in a section view.

- Visually, the Flex conduit should basicly look like a standart conduit and on "Coarse" detail level simply like a line (maybe dashed, that's at least our standart)

- As Kevin wrote, minimal bending radius, adjustable in the electrical settings - conduit - size (just like for the already existing rigid conduits) would be nice too.

- The "Paralell conduits" function should also be working with the flex conduits, if possible.

- Also good would be the ability to connect the flex conduits to rigid conduits (like Flex Pipe / Draw Pipe)

 grafik.png

 

 

As an alternative to a completely new flex conduit family with flex pipe as a template, you could add a bend fitting to the existing conduits that can be draw and adjusted like a spline. (if that's easier / faster for you to add)

Or you could add the "Draw" option to conduits, which is known from beams. (They can be placed as Splines.)

With the conduit we use today, it´s not possible to design true BIM Projects (Plan as built). With three significant improvements, we could avoid most of our Problems we have today.

 

1. Flexible Conduit

In concrete buildings most of the conduits are flexible. To draw realistic Models, electrical engineers need a flexible conduit, like the flex pipe.

 

Picture of flexible conduits in a concrete ceilingPicture of flexible conduits in a concrete ceiling

2. Systems for Conduit

Conduit can contain different Type of media, for example a data-cable or a lighting-connection. To specify what’s the conduit used for, we need the possibility to classify them into Systems.

3. Wire in Conduit

Conduits contain different wires (single or multiple). For true calculations there must be a possibility to add wires in our conduits.

I would like to echo the need for this. We like to use Revit to model street light and other outdoor electrical systems, mostly because we have all the drawing standards set up and prefer not to change tools unless we need to, and also because the callout features are very helpful. And often we have buildings with associated parking lot lighting and those buildings we are designing in Revit. 

 

Street light ducts are 32mm and easily bend to follow gentle curves. We draw these with model lines at the moment but what we'd really like to see is a flexible duct system that responds to control points and vertexes.. similar to an AutoCAD polyline. 

 

I tried using a flex duct and it sort of works, but I feel the ability to modify the path after it is placed initially is absolutely required. If the system had some knowledge of min bend radius that would be sweet but I'd rather see something soon rather than wait for something really fancy. 

 

Is there an idea posted about this?

As it is possible to simply do Flex Duct (FD) and Flex Pipe (FP) in Revit, it would be great if we also have a Flex Conduit possibility (and not the flex pipe edited family originally for Plumbing purposes, or some adaptive generic made up ones).

There is no option for flex conduit in Revit platform, but in actual site condition, conduits are sometimes twisted, slightly bend for coordination purpose. So whenever we try to match those as built conditions (Point cloud), we are getting error warnings. If possible then add flex conduit option or add vertex option in conduit.

Hi,

The Idea is that we will have Electrical Flex Pipe in Revit.

When we must modelling 3D pipes in Revit, we don't have an option to modelling flex pipes for this.

We have only the option to modeling "no flex" conduit.

Kind regards.

We are also in North America and use the NEC.

In addition to the types listed above by Kevin.Laskowski, I'd like to see ENT Electrical Non-mettallic tubing (Smurf tube), which is very similar to the corrugated pvc linked by Sean.Lawrence above. | NEC Article 362 Type ENT

Also type MC cable| NEC Article 330 Type MC

Flexible Metallic Conduit has a designation in the code as FMC | NEC Article 348 Type FMC.

 

As far as the functionality of the different tools flex duct/flex pipe, I haven't had much of a chance to use them, we've been modeling some of our flexible conduits straight with the standard conduit system families.

CABLE LAYOUT FOR SUBSTATIONCABLE LAYOUT FOR SUBSTATION

Hi

the above cable layout is done for a subsation project.

does any one have a idea for cable laying , where the cable used is flexible (flexible conduit properties) , restrains to a specific bending radius , and can contain a no. of cable within a master cable which can be seperated for further connection.

 

in fact, my job very very need to draw the flexible conduit and electrical rubber cable according to the point cloud, but it is not in Revit platform at present, it is so inconvenience.

I hope it will have added soon in next Revit platform or product updates.

Searching for an answer to this problem (newer modeler) and was disappointed to see that a post from 2016 still has no good solution. This definitely has my vote, having a hell of a time modeling massive amounts of conduit racks that transition from rigid to flex multiple times. Hope we will see this is a new version before too long, seems pretty critical.

@Martin__Schmid for displaying purposes- yes it works either flex duct or flex pipe. However, there is something _*terribly*_ wrong about suggesting that as the reason autodesk would _not_ implement the change as suggested. Something that makes BIM pointless. The whole appeal of BIM is that I can obtain supplementary info such as costs, material lists, and _very important_ information for integrators such as what is what is shown, what discipline does it belong, etc. Conduit and pipe, while pretty much similar in nature, not only do they follow very different construction guidelines, _they are used for very different systems_ . Conduit is used as a raceway for cabling, ducts are for transporting air in HVAC and pipes are for fluids (liquids or gasses). Not only is suggesting to use a type of material that is not the correct one antithetical to BIM, but: 1. Filters would not work as intended. I do _not_ wish to lose half of my raceways in a view because what I wanted to filter out were the other disciplines. 2. In the real world, ALL conduit may be bent with the adequate use of tools; having the program adding fittings not only makes listing materials harder, it limits what the model shows in comparison to the real world. Case in point: you need to make small bends to a conduit in order to couple it seamlessly to a junction box of _any_ height. The fittings create a minimum height for these transitions that is limited by the bending radius of the fitting. 3. Flexible types of conduit (FMC and LFMC) have their own accesories- again it makes listing materials harder and unallows the model to draw the adequate accesories.

We want to use Synchro 4D, problem now is, when using automatic Filters to place 3D content into scheduling fragnets. All of our flexible electrical conduit has to be filtered under "Mechanical". If we were at the GC level putting this together, All of our content would be accidently placed under the Mechanical subcontractors timeline. If there was a family named electrical flexible conduit, no work arounds would be required. Please consider this post having value. Mechanical Flex alone will not compliment 4D scheduling anymore.

I work as BIM manager for one the UK's largest energy providers. I've been Revit user since 2004, certified trainer 2016-2019 and to date there is no cable function. Cables are one of main function of the business. As the business transitions from 2D AutoCAD to Revit the need for a cable function is a must. We build MV, HV and HVDC substation across the UK connecting wind farms, solar farms, battery storage and multi terminal links to other countries. There is a LV, MV, HV cable add-in at $500 for each type but it's just a conduit system and will not perform as needed (Waste of money). Revit hasn't changed that much in 18 years with minor changes year on year. Can the Autodesk Revit developers look into this as the building blocks are already there is just needs to be developed? I hope I'm not searching for solutions 10 years from now. I'm sure I could get most of the business to vote (22,000+ employees) if this would make Autodesk to listen

The ability to use an arc (or a spline) for conduit would match reality in trenched conduit situations.

Many times the trench is cut in an arc to eliminate elbow fittings underground.

Collaborator

I have never modeled conduits the way you are describing, but I've seen the radius of the bends changed from their default values, to something like 240" (20ft). This gives a more realistic visual of underground conduits. 

 

You can always take this a step further and create a new conduit standard that uses the 240" as a default bend radius, but I feel like a 240" radius may become problematic in some areas where stub ups are closer together, and Revit won't let you reduce the radius to anything less with out of the box content - so it may be a little trial and error determining if this is a good long-term solution or not.
