CLF Shape Bender
Bend a group or component to match an existing curve.
CLF Shape Bender

Create a shape to bend.  It must be a group or a component.  Then select a single horizontal (red axis) line to use as the base for bending.  Then select the curve that the shape will bend to match.  Wait for it to think, then it will show a grid and preview of where your object is going to transform to.  Press the UP Arrow key to toggle the orientation of the bend.

Access the plugin via Plugins > Chris Fullmer Tools > Shape Bender, or there is a Shape Bender toolbar.



Dankeschön für die Mitwirkung.

Not working, tutorial isn't really helpful. Anybody got a better alternative?

cant make it work it just does nothing maybe because it's not assigned what's the solution blease

Make sure your shape is grouped.
Then draw a line on the group along where you want it bent.
Draw a target; curved line or half circle or whatever you want to bend the shape to.

Select the group.
Invoke the extension, the cursor will change to an arrow with an underline under it, the group will appear to have been deselected, engore that.

Click on the line the you created on the grouping, then click on the target line.

You sould get a grid for how the shape will bend. Hit enter and vola!
If you post your email address i will send you a working drawing.


thanks a lot sir that was very helpful ....the mistake i was making that am drawing the line away from the group not on it
it's very kind of you to respond and explain in details
best regards

Shape bender tool is an awesome tool. I use to make my client website visuals. The website is PCSO lotto based and the design is some kind of difficult. So, i use this tool to make it possible and my Swertres hearing website owner is happy


This extension doesn't work in SketchUP 2018. I receive error on SU start, and extension takes no effect.

Does not work for me in 2018.

I followed the video. Simple rectangle 2x4x1".

The script draws a red grid bent correctly, but the green grid is not bend; it show the targe shape drawn at ~60% angle to itself.

Not sure what I'm doing wrong.

I got this to work on 2018 by uninstalling and reinstalling the extension. Who knows why?

I am trying to download it.

*** Why this extension needs granted permission to access my personal files in my computer?

i can't work with the plugin as it seems to be unsigned.
Any suggestions ?

Did you figure this out? I'm having the same issue.

I had a problem at first with my group "exploding" all over the place after the transformation. I moved the shape to origin and drew the line directly on the red axis as others have suggested and it worked great.

I needed to bend my shape to a dome, I did this by first bending it to an arc, and then moving the bent form back to the start position and rotating it 90°. Bend again... dome! Very pleased.

Thank you Chris!

For anyone still have any problem with this plugin (after doing exact same thing as the video tutorial), try to start using this plugin in completely new file. I encountered problem with "red axis" and "raw surface" when i working on my existing file, then i try again in a new empty file, do exact same steps, and it works perfectly fine. Maybe it helps?

When I tried to select the first line after the Group it said 'select a line that has been drawn on the red axis'. It looked like I had done, so I am a bit stuck!

Exact same thing is happening to me , have you resolve it yet ?

My favourite!

Merci beaucoup

Yes! Thanks

Yes! Thanks

Why does my group being bend switch sides of the bend-to curve? Bends to curve find then, the last six segments of the line, switch to other side.

Been working on it for days. Rarely it'll work. Tried all kinds of new curves, looking for errant lines, etc.

I am trying to download this extension but running into a problem. Everytime I download an ext. the download immediately recognizes it as a sketch up file. when I select the download from the list it tries to open sketch up and load a model... and of the program puts up a message that it does not recognize the file as a sketch up model. Not sure what is going on here but I am sure it is a simple fix for a pro. I am a user but not used to plugins and extensions. 

please i downloaded the plugin and it didnt work i didnt even show in my sketchup i dont know why !!

when i click the component, then click the bender tool no option to select the line comes up with the white arrow. please help!

worked like a charm on 2017

Works good..
Had fun curving my furnitures too..
Thanks and congrats to the developer

Lo he probado en SketchUp 2017x64 con Windows 10x64... Y es totalmente funcional. Recuerden aplicar los pasos tal cual se explica.

I've tried this on 15, 16 and 17 on my Mac and can't get it to work.

It looks amazing, and I really need it! Anybody have tips or suggestions?

I believe you need to add Windows to your MAC in order to make may of these plug-ins work.

Working well 2016 Pro - thank you! Beautiful work!

hello.thanks you

I just tried it and it worked for me.
I have had problems with other extensions, but this one works great (and very cool!)

I installed using extension warehouse from within Sketchup Pro, maybe that helps...?

It is working great! Thank you so much for detail tutorial as well.
