Bezier Curve Tool
A tool to create Bézier curves.
Bezier Curve Tool

The Bezier Curve Tool is used to model smooth curves that can be scaled indefinitely and aren't confined to the limitations of the Arc tool, allowing for more natural and intricate shapes. 

To draw a Bezier curve:

  1. Choose Draw > Bezier Curves
  2. Click to set a start point
  3. Click again to set the end point of the line
  4. Move the cursor to adjust the first curve
  5. Click to apply the first curve
  6. Move the cursor to create the second curve
  7. Click to set the second curve

Why does this extension show as unsigned when it's installed? It appears to be missing a signature file.

You can ask the author Thomthom. I first installed this around 2015 and like any script you take the responsibility to know what it will do before downloading. Since the 2017 release ALL extensions needed to be re-signed by the authors.

I can say he has released Quad-Tools and Vertex Tools since then. If these are the next steps or progress to the original script. These have been signed for 2017 there is no need to re-write this one. It works for 2016 and down versions, for those who chose not to up-date S-UP. and the two new tools take it to another level.
Those two you pay for, so I would guest to say that is his focus.

Like anything you install on your machine, you are responsible for what happens. Use your judgement but 143,883 users say's something for his creditability.
...Peace.....

I'm using Sketchup17 and neither the B-spline Curve tool or the Bezier Curve tool (I've installed both) seem to be very easy to use. I just want a simple curve on a face. I successfully create the endpoints and shape the curve but when I try to stop the curve gets all "s" shaped and crazy, or , at best, it has a gap in it and still is not the perfect shape I drew.

So I must be using it wrong.

What should I be doing?

Try drawing a regtangular face and make it a group. Draw your curve on it as SUP will say your on the Face. Make it a component and move and rotate it as you like. Cool trick is it maintances its ability to be edited as a curve by clicking it and then right click offers edit points to adjust it. Remeber it is a component so if you have a bunch of the same ones, Make it Unique to elimenate change all copies.

Also when you first open the tool.... there is a 3 in the VCB box. WHAT I DO (claiming my opinion) is hit backspace- then type the number 2- then hit enter. This just gave you the option to only use two click to set the curve. Instead of the three clicks needed to set the curve. It makes it easier to use. ...Peace.....

needed to add, clicking the curve to highlight and from Edit> click make group. It is a short-cut and I set a key board short cut up for it. It works for lines also, NOW you can right click on it and change to a component. To make use of the two editing properties together with practice. Adds a cool editing trick for you.

Thanks William R. I had figured out most of what you suggest, mainly using a new rectangle on the plane where I want the Bezer curve, then successfully drawing the curve (always on the face), then deleting the excess part of the face. Works well, but your tips about making it a component and a group makes it much more powerful

I am using SketchUp 2017pro.
The Beziertool menu does not come out even if right clicking.
Although I installed the plugin, it is in a state that I can not uninstall why.
It is modeling in 2015 version only to use this tool.

It's rotten this exists at all for Sketchup 2017. It's clearly outdated and based on the comments here, Trimble Sketchup doesn't care either. It should be a native tool, plain and simple, and limping along with an extension build 5+ years ago with no toolbar, no hotkey (by default), no post creation editing (shy of moving the whole curve...try changing an endpoint and you'll see what I mean). Just terrible.

I completley agree!

Het werkt!
Ben gelukkig :)

I am new to SketchUp
I installed the extension, but on the Extension manager it shows as unsigned and it doesn't work. How do I get it to be sign for it to work.
Please help.

Thank you.

I am using sketchup 2015 on windows 8. This plugin is successfully installed, but does not show up in the extension menu, neither in right-click. This also happens to some plugins. What can I do with this?

William R's picture

It will be listed in DRAW from the Menu Tabs just scroll down. It wont show from View>Toolbars either, but if you go from Windows>Preferences>Shortcuts. In the Draw selections it will show up and you can assign a keyboard shortcut of your choice. I have V set and the tool has 2 or 3 click( control point) options.

So I do V>backspace then hit 2 this set the curve to build with only 2 clicks. By doing V>backspace then 3, it sets the standard 3 selection point options that is common with setting Bezier curves. VERY USEFUL tool....

Hi, it happens to me as well. Have you sorted it out yet?

Works OK but you can't go back and make changes to your curve later once you double click out. Plus it doesn't make a face if you connect them even when I tried to use "make Face" extension it still didn't work. As I need it to make 2D landscape pathways this is vital for me so I will be uninstalling and looking elsewhere.

Draw a rectangle bigger then the curve you need. Layout the shape of your curve on it, then connect the two opened ends. While it is closed or not you CAN edit it anytime, highlight the curve. A simple left click on it will do it. Then right click when highlighted, select the first of the 3 edit options. There will be a yellow line with 3 '+' signs as edit points to drag. Or left click on the yellow line itself to add as many edit points as you want.

Extremely useful, since I got the hang of the pen in Photoshop this kind of tool is my bread and butter.

Although I'd appreciate it greatly if the tool itself was available in the tray rather than in a menu, it'd make things a lot faster and substantially more ergonomic. Apart from that, great plugin, definitely a must.

I set a keyboard short cut for the tool. I use V, after I select it, Sketch Up will put a 3 in the VCB( measurement box) I hit backspace to clear it, then select the #2 numeric key. Now I only have to set the first point then set the end point. Hold down LMB to manipulate and release when I am satisfied. With a context click you can go back in to edit or add control points to further establish the curve. Speeds things up a bit.........

Hi, I cant install the extension

Can't install it

thank..im try to this tools.....

Do I have to use second curve? This would be great if you could press right click to set path after first curve.

Just installed this an hour ago and I find it to be fine for my needs. All I wanted was to create a push/pull object to round the corner of a "block of wood". Worked just fine.

PIM F: I first drew a rectangle and then selected the new bezier curve tool. Click on a point anywhare on the perimeter of the rectangle and then move the mouse and click on another perimeter point. then just move the mouse to create a simple curve--then click. Then move the mouse some more to make the curve switch back on itself and create an "S" shape. Click again. Now the rectangle is subdivided and either piece can be pushed/pulled.

NOTE: do not click and drag. Just left click down and release. You can click and drag, but I don't think it was meant to be used that way.

My installation experience:

Open Sketchup (I use 2016 Make 64-bit under WIN7PRO)
Click on Window Menu, select "Extension Warehouse"
In the search box at the top, type "bezier curve tool"
locate "bezier curve tool by SketchUp Team)" in the list and click on it.
The window will now have an animation and a large red button labeled "Install"
Click on install. Click yes to the next prompt about access to filesystem.
You should now see a prompt saying that installation is complete.

No need to restart SketchUp.

Hope this helps someone.

I am on Win10, SketchUp 16. I have tried downloading this ext many times. I have restarted program as well as computer. The loading process seems to happen, with a window stating 'ext did not load, need to check ext manager and click box for ext'. The ext name is in ext manager, but I cannot click the box. Any suggestions would be so appreciated, as I know this tool could save me soooo much time!! Thank you in advance.

i am using sketchup 8 the instructions for installing Bezier Curve Tool is incorrect, can someone please tell ma how to do this.

harap W.'s picture

after you download the extension file (.rbz) go to Windows/Preferences/Extensions and click on Install Extension... button. Make sure you browse to the location where you downloaded and install it. RESTART Sketchup, go back to Windows/Preferences/Extensions and make sure it is selected with the checkmark. If not then select it. You may need to restart Sketchup again in order to load properly. If all installed properly it should now be found under Draw as Bezier Curves

Hi, How do you install it on Mac OS?

I'm looking for a bezier tool that works like Illustrator's. This one certainly does NOT. The others I've tried all have their quirks as well. Is there an "Illustrator" bezier tool for SketchUp?

Joe C.'s picture

Seems like this doesn't work good with the Follow Me tool and the like. Objects break up and just get weird when they follow the bezier path. If I go back and use the stock Arc, Line, etc.. the extruding works fine.

Why does it say my time has expired and I can no longer use this feature? I have the 2016 sketchup pro

Robert T's picture

I can't get the curve to draw only in 2d. No matter what I do. I do not expect a reply from Trimble. I do not expect them to fix it. Ever. So dissapointed in Sketch Pro so ofetn, and yet there's nothig out there to compete with it. Get it together folks. I paid $500 damn dollars for this. Incompetence.
