3skeng 2018 Pipe (MAC and PC)
Generate and edit pipelines, work with standard fittings and components
3skeng 2018 Pipe (MAC and PC)

Put "3skeng Pipe" to the test within a free 30 days trial period of the full version!

In the "learn" section of www.3skeng.com you can download learning material in SketchUp file format that guides you through the basic handling of 3skeng extensions!

3skeng Pipe is an extension for the design and documentation of MEP and 3D piping and rectangular ductwork. It is part of the 3skeng engineering package that also contains 3skeng Mount, 3skeng Steelwork and 3skeng Channel.

But let's just tell you guys some more about the tools and features of 3skeng:

3skeng Pipe (conceptual mode)

All you need to model conceptual pipelines is integrated in this tool.
Pipes, T-pieces, Y-pieces, reducers as well as elbows are generated and connected together in a smooth workflow with only few mouse-clicks.
You have access to the most common standards (ANSI, ASME, ISO EN and JIS) and determine the dimensions of fittings with only a few clicks. Magnetic points and a memory function are powerful parts of the tool and assist you in the process.

3skeng Pipe (detail mode) 

With just one switch you can convert 3skeng pipe to a tool working in the same intuitive way with detail library elements. 3skeng edit, connect, list and label can be used in the same way as in conceptual mode. Even a combination of detail and conceptual pipeline elements is possible.

The embedded auto-pipe function helps you to connect 3skeng components and allows you to select one of the possible configurations. Auto-Pipe is available for both conceptual and detail mode.

By the way, we added an improved handling of IFC-properties for 3skeng elements during edit and connect copy!

Libraries for 3skeng Pipe (detail mode)

Libraries with several ten thousand parts in metric and imperial sizes are available in the in-app store. Library parts are based on standards or on popular pipe & tube systems and are grouped by material. Manage your libraries within the 3skeng client.

3skeng Edit & Rotate

Edit and re-arrange your pipe, fitting and component arrangement. The edit tool is so intuitive that it nearly follows alone your ideas. Use magnetic points or the input of numeric values in a way you know this from SketchUp.

3skeng Connect

Move or copy segments of a pipe arrangement to a new location. Magnetic points will help you to connect the elements exact aligned to the pipe center. All elements will be aligned in the pipe direction, which helps you to generate and change models very fast.

With the new feature "Multicopy", all selected elements stay glued to the mouse until you press “Escape”!

3skeng Label

This tool enables you to add multi-text and labels to groups and components. Various adjustable parameters allow individual adaptations to the particular label task at hand. During the automated alignment you determine the position and distance of the labels.

3skeng List

Select parts of your model or the entire pipe model and generate a list with detailed part information. You can easily transfer the list content via the clipboard to your own calculation sheets or bill of materials.

3skeng Client

Use your 3skeng client to purchase, install and manage 3skeng Tools and Pipe libraries.

License terms in short

Great program, I appreciate it very much. That said, there are some bugs as you know,

I just bought the 'grooved piping library' it was supposed to include a range of *valves* but instead I got what appears to be a fire sprinkler only library, no valves in fire sprinkler systems just 3 types of line strainers,

I need to run grooved piping with the usual assortment of various *valve types... similar to what you include in your welded steel pipe library.

I have tried various grooved pipe sizes, and in any size from 2 inch on up to 12 inch, no valves or other 'instruments' to use your term, were available, only 3 types of strainers,

Fix me up, I will appreciate it.


3skeng©'s picture

Dear Phil,

Thanks for the good Feedback and the question about the "missing" valves.

To access the available valves for the size at hand, you have to switch from "Grooved Strainers 45/90° 2-12in (in-mm)" to "Grooved Valave 2-12in (in-mm)" by clicking on the group in the 3skeng client window.
In chapter 9 of our “3skeng-Starting-Guide.pdf (http://www.3skeng.com/download/3skeng-Starting-Guide.pdf)” we provide sketchup-based learning files that guide you through the tools and their functions (e.g. changing groups in the Pipe detail mode).

We also provide pdf files of the library content so you can exactly see what kinds of elements and sizes are availble in the library. You can access the pdf-files by clicking on the "my 3skeng" tab and then on the button "manage libraries…". Selected a library in the pop-up window and scroll down to the very end to find the link to the pdf.

Please feel free to contact us at support@3skeng.com in case you need more support or have additonal questions.

Best Regards, Hans, 3skeng

I am unable to select a check valve on a drawing, it reverts to ball valve. How do I do this or what am I doing wrong?

3skeng©'s picture

Hello Lance,
On our Homepage, we provide the PDF-file “3skeng-Starting-Guide.pdf” for download.

In chapter 7, you can see how to access PDF-files with the content for every library. Maybe the check valve is not available for the size you need?

You can also contact support@3skeng.com in case you need more Support!

Best Regards, 3skeng team

The features are really great! I loved it

Great product, but your super slick auto pipe routing feature seems to have dissapeared from 2017 version.... what up with that, or am I missing something?

3skeng©'s picture

Hello Phil,
On our Homepage, we provide the PDF-file “3skeng-Starting-Guide.pdf” for download.

In chapter 9, you can find learning files for the 3skeng tools. Please check the files "Learn to use (1) 3skeng Pipe conceptual" and "Learn to use (2) 3skeng Pipe Detail" as they each contain a section about the auto-pipe Feature.

You can also contact support@3skeng.com in case you need more support!

Great product, so far it has worked flawlessly and helped speed up production significantly.

My one concern. I work in the United States which uses Imperial units as the standard. Unfortuanately for me, 3skend provides detailed plastic piping only in Metric units. Is there a way for me to switch the standard metric pipe library (which I won't be using at all) for a imperial one? I know that I can buy the imperial package but it seems very limited that I can't choose my preffered units without having to buy more pipe libraries. I would gladly trade the three metric libraries that comes standard for just one imperial library.

On another note, its impossible to find contact information on the company's website. So I have to resort to leaving a review/comment here.

Other than that, its a fantastic software package.

phil s's picture

I have the complete piping, ductwork and steel libraries that I need (imperial mostly).

There seemed to be some bugs with the software adding in a PVC section while I was drawing copper pipe, and some other things that may or may not resolve as i get more practice with the softrware.

I have not tried the auto rouing feature yet, if that works it will be a total winner.

I did not see the valves and instrumentation librares shown in the demo video, those are still pretty limited. The 'valve selector' in groved piping does not bring up any valves, instead it only brings up a range of line strainers or capped tees... thats a bug for sure.

All in all I think this latest version is quite a serious upgrade, but also quite a bit of giant step that the developers are still struggling with.


-Where is the Unistrut in the steel library? or did I just miss it?

-Where are the valves in the grooved steel pipe libarty?

-Why did my copper pipe drawing refuse to continue wth copper and instead switched to PVC, later it was able to continue with copper. I find a lot of piping wanted to revert from what I was drawing from that, to PVC for some reason, maybe practice will solve the problem, maybe its a bug

Otherwise, I give the developers 4 stars in my book.

andre.klatt@shk.com's picture

Hello Phil,
First of all, thank you for your detailed feedback.

We invite you and all other users to contact support@3skeng.com in case you come across any 3skeng-related issues.
Please let us know what SketchUp and 3skeng version you use along with a description of the problem, clariyfing screenshots and maybe a SketchUp file.

Concerning your Copper library issue
We kindly ask you to send us a SketchUp file that includes the elements that seem to cause problems (like the Copper and PVC occurance that does not allow you to add a valve). That is the best way to enable us to help you in your specific case. We are always interested to further improve both our software and library content.

We tested Copper libraries and did not find a bug so far.

Concerning your Grooved library issue
IMPORTANT: When you start drawing, 3skeng switches to the Library you used last time to draw a component.
This is convenient if you draw all your components in the same Library. But you’re right, may be this is not a good idea. We will consider to change this confusing behaviour in the next release.

To avoid mistakes, please check the Library showed by the 3skeng client window again, when you are about to choose a component.

In general, there is more than one reason why you cannot find a valve or other fitting types to connect:
- The desired element is not available for the current connection size or type, e.g. you may have to add a flange first.
- The desired element is (currently) not available in the library.

To help you and other users to get a detailed overview about the library content, we provide pdf-files.
You can access those in the tab “my 3skeng” of the 3skeng window by clicking on “manage libraries…”.
The link to the pdf-datasheets can be found at the end of each library description (after clicking on the [..more..] botton).

If you need additional elements that are not part of the library, you can make your own drawings compatible with 3skeng. Just follow the tutor “3skeng compatible groups & components” you can access by clicking on the gray botton in the 3skeng window tab “tutor”.

The Unistrut profiles are not part of the Steelwork library. We currently develop a new tool that includes C-profiles, their connection elements and best of all pipe and duct support that connect to the profile.
You will be able to design your installation including all necessary support!

Best Regards,
Your 3skeng Support Team

Regarding 3SKeng PIPING ... when drawing copper pipe there are only steel type flanged valves available, not any copper sweat conntection valves.

I have a similar problem PVC and CPCV piping... nothing showes in the libraries... when the valve icon is available it only brings up steel pipe type flanged valves.

Am I missing something?


3skeng©'s picture

Hello Phil,

The current copper library version does not contain valves, the upcoming next version will.
Both the PVC-C and CPVC library contain valves, so you should be able to use them as long as you have the appropriate library in your account.

As we don't know your user account, we can only offer you to send an e-mail to Support@3skeng.com and we will further look into your problem.

By the way, you can access libraries in the 3skeng client tab by clicking on “manage libraries” (see screenshot). Here you can learn more about library content as you can find detailed pdf-files with the library’s content for most libraries.

We are currently working on updates of the libraries "Imperial Steel", "Imperial Stainless Steel", "Metric Galvanized Steel", "Metric Copper Pressing Socket" and "Metric Stainless Steel Pressing Socket".

There are also brand-new libraries, e.g. "Imperial Ductile Iron" and "Imperial Galvanized Steel" soon to be released.

Respected sir,
i have a problem to run this extension, i downloaded it its trial version,but it is not seeing yet my skp screen. Pls help......

andre.klatt@shk.com's picture

Dear Mohan Lal,

3skeng 2014 will be installed for exactly the same user account who execute the setup. This may be a reason. If you have installed - as usual - as administrator and then try to use 3skeng as another user, you may not found the 3skeng extension in your SketchUp 2014 or 2015 application.

Please check additionally if the 3skeng Toolbar probably is hidden or untagged. To check the tagging go to the SketchUp menu "View > Toolbars", look for the entry "3skeng Engineering 2014" and ensure this entry is tagged.

In case of there is no 3skeng entry in the list of toolbars, go to the menu "Window > Preferences", go to the entry "Extensions" and check that the extension "3skeng Engineering 2014" is available and tagged. Otherwise 3skeng is not properly installed.

3skeng pipe is a great add-on used this for designing my furture dream aquarium. user friendly and exellent customer service. highly recomend using this.

Thomas P.'s picture

Really like this extension!

Couple of questions:

I am working on a project where slip-on flanges are desired for their compactness. Are you thinking about adding other flanges to the system?

Why are the instruments that can be imported limited based on size? It would be really nice to import 16" gate valves/ball valves, etc. but currently only butterfly valves are allowed once you reach a certain diameter.

When in detail mode, why are there not 22.5 degree bends possible? I like that they can be created in conceptual, but wish they were available in detail as well.

Once again, great product, just a few things I have noticed using it!

Keep it up!!

I would really like to be able to modify, or add my own pipeline components into the UI (example: properly dimensioned 150# blank flange.) Is there a way to do that other than editing them manually?

I love the extension, and it has saved me so much time in my projects. Well done!

3SKENG is the BEST plugin for modeling and designing piping systems. Both the conceptual and detailed modes are great. Just like Sketchup the UI is extremely intuitive.

Thanks you for this plugin
