I've just updated this plugin and now I can't find how to put a keyboard shortcut for these tools.

Is there a new way to achieve that?
In the Suforyou menu the isn't any slice items.


I tried to buy the extension. Unfortunately I get the message "Card Number invalid". I've tried this with two different cards in the meantime. And I also contacted the credit card company. In the Sketchup forum I found posts with similar problems. I suspect a problem in the Extension Warehouse Shop.

Hi. Congratulation on making one of the most useful Sketchup plugins.

I have an idea to make it twice time useful :)...simply by adding inverse function. So it could not only trim SU geometry, but also extend it using the same logic in picking 2 point lines, faces or 3 point faces...

Even more useful would be possibility to select a few faces, or curved surface as an "edge" for trimming, or extending.

It would be powerful feature.


I will try to be clear in english ( I'm french :) )

Does s4u Slice keep the layers names of the 3D sliced to create 2D groups ?
Does it also keep the components attribute/name ( as standard sketchup section cut ) ?

As an "architectural" BIM drawer, I am looking for a plugin that respect my 3D drawings with layers and components names when I create 2D group section cut.
The objective is to slice my 3D models to create 2D drawings for Autocad / others.
On that case I am actually losing a lot of time re-fixing layers names on the 2D drawings realized with section cuts.

Any advise, help will be very nice :)



Suforyou's picture

Hi Julien! I will update in the next version.


many thanks and usefull for others only still working with 2D ACAD drawings :(
I love 3D, I love BIM, so I love Sketchup :))


Cesar N's picture

Amazing plugin, So useful.

Is there an option for the Detached component/group to inherit layer and material from the original one?

For some reason I remember that the previous version did that.


Suforyou's picture

Thanks,I check it soon.

When waiting for the support of version 2017?

Just paid $10 for this. I install using the Extensions Warehouse, install is succesful according to it.
Try to use the toll "This trial has expired"

There's no way to uninstall, and it seems this problem is happening all lot with a lot of unanswered comments. We should either get a fix or a refund!

It's truly amazing that "Sketchup Extension Warehouse" and "Suforyou" allow paying customers (me included) to twist-in-the-wind after paying hard earned cash for a dis-functional plugin (installation or whatever) . . . no response or meaningful support or meaningful remedy.

Suforyou's picture

You see this link : http://help.sketchup.com/en/article/3000263
Tip: After you purchase an extension, the Extension Warehouse doesn’t offer refunds. If you’d like to try out an extension before you purchase it, look for an Install Trial button, which enables you to try how the extension works before you buy it. If you’re having trouble purchasing an extension or would like to contact us about an Extension Warehouse purchase you’ve made, fill out our Customer Service Contact form and, from the You Would Like To drop-down list, select Resolve a Purchasing Issue.

@Suforyou , for some reason you are not understanding your problem . . . paid customers are not allowed to use the plugin after a successful purchase and successful install … the message received is
that the trial expired (when it's not a trial) and/or the message “not licensed” (after paid and installed).

Your links to “Ssketchup” are not helpfull
Sketchup' links are not helpful for the issues after purchasing your plugin(s)
Sketchup refers back to the you;
Contact extension authors directly . . .
. . . contact the plugin developer for . . .

Not a good thing.

Suforyou's picture

I mean you contact to Sketchup If you’re having trouble purchasing an extension because Sketchup manages your licence and payment.

Please read above . . . It's not a purchasing problem.

Did you tried to launch Sketchup as administrator and use slice once?
Perhaps it's a Windows issue... if SU can't write to the c:\\ or user\appdata\roaming etc. there is often problems.

Can't figure out how this works, even after watching the video more times than I want to count. Click a button, then what? Draw a line? What about my section? Select what? Everything? Huh? What's it doing? Where did those pop-up menus come from in the video? They're not working for me... Windows only feature? Just naming the boxes isn't enough to tell me how the functions work.

Some kind of step-by-step in any European language would be really helpful - preferably English, French, Spanish but at this point anything I can read and paste into Google Translate would be nice.

For now, I'll avoid this extension. I've pulled out all my hair in frustration and will have to wear a hat until it grows back.

My main use is for cutting groups/components.
1. select a group/component
2. use the 3rd icon from the left (detach) of the slice tool
3. draw the cutting plane (you can define it by drawing 2 or 3 points by right-clicking; if you are in a 2D geometral view - top/left, etc. choose 2 points and draw a cutting line / if you are in a 3d view (axonometric or perspective), choose 3 points - usually 2 horizontal points and one vertical one)
4. voila, the group/compo is sliced in 2.
if you cut a compo, 2 unique compos are created.

Hi Phuong.

I must say that although all your videos are (very) impressive, your pace is so fast that the major part of living creatures on this earth must be wondering what the heck you are doing and what magic you are using.

I'm a long time fan of s4u-components and s4u-slice.
I'm trying to understand s4u-transformer and must say that the learning curve is a bit steep. :D I hope to be able to do some Rhino-Grasshopper stuff in Sketchup by mixing all your scripts with thomthom's QuadFaceTool/VertexTool/SubD.
it's probably faster and easier to do that in Rhino directly but I'm an old SU user since v2 and well, I feel like a vintage car owner, don't wanna swap my 1957 Cinquecento for a sparkling new Prius 2016... lolol

Hello, I have contacted forums.sketchup and no news so far. I still don't understand why my license is not active.
It's so frustrating and for sure I wasn't expecting such a poor customer assistant.

Thanks anyway

I have install the new sketchup 2016 and I have the same issue again with this plugin and my license for it.
Under extension warehouse - My extensions, it said "Trial expired" and I can't install it or unistall it!

I'm completely mystified on how to use this plugin. I just want to select an object and an intersecting plane, click one button and have the object divide into two objects along the plane.

Do you select the objects first, or select one of the four buttons first?

Are they four separate processes with different outcomes, or are they four steps in a sequence that are necessary for a single outcome? Why do I get error messages a few seconds into playing the video instructions? Is there a set of written instructions how to use this plugin?

Suforyou's picture

You select the objects first,then select one of the four buttons.
Button 1 - Slice
Button 2 - Cut
Button 3 - Detach
Button 4 - Create group section
you can select points for set plane or Preselect Section Plane.

Hello su4you

Your scripts are pretty unbelievable!
Slicer is soo amazing.
But can you tell me how to speed up the slice process?
Is it best to explode the group/compo to the lowest possible level?

Edit: I tried by exploding all the meshes until the primary group level and slice is waaaaaay faster. I guess it avoids the creation of unique components and groups, which takes huge amount of time and memory on complex models...
And I am amazed that Undo works fine, an useful accomplishment.

Edit 2: is there a multicore version in the oven?

Suforyou's picture

It's best if you explode all level in GC.
A multicore version is complex . It is unable.

I purchased but cannot use. Mine says "trial" and has expired...
What do I do about this or who do I contact?

diane a's picture

finding it hard to follow the video's to understand how to use this tool..do you have anything besides these? Thanks

Suforyou's picture

you can look the prompt in status bar.

diane a's picture

thank you for all of your awsome tools and for making them affordable. Really appreciate.

Jaimie F.'s picture

Great script, very fast! Is there a way to fill the edges with the same texture/colour when you perform a slice? Would be a great option if not! :)
