Soap Skin & Bubble Plugin for Sketchup: A Review and Tutorial
Soap Skin & Bubble Plugin: How to Model Organic Shapes in Sketchup
Sketchup is a powerful and easy-to-use 3D modeling software that can create realistic and complex models of buildings, furniture, landscapes, and more. However, one of the limitations of Sketchup is that it is not very good at modeling organic shapes, such as curves, spheres, bubbles, or blobs. This is because Sketchup uses straight lines and flat faces to create geometry, which can result in jagged edges and unnatural shapes.

Fortunately, there is a solution to this problem: the Soap Skin & Bubble plugin. This is a free plugin that allows you to create smooth and flexible surfaces in Sketchup using a technique called NURBS (Non-Uniform Rational B-Splines). NURBS are mathematical curves that can represent any shape, from simple circles to complex organic forms. With the Soap Skin & Bubble plugin, you can easily create a NURBS surface inside a closed loop of edges, and then inflate or deflate it to create different shapes.
How to Install and Use the Soap Skin & Bubble Plugin?
The Soap Skin & Bubble plugin was created by Josef Leibinger, a German architect and software developer. You can download the plugin from his website or from the Sketchup Extension Warehouse. To install the plugin, you need to follow these steps:
Download the zip file of the plugin from the website.
Extract the contents of the zip file to a folder on your computer.
Copy the file "su_soap_skin.rb" and the folder "su_soap_skin" to your Sketchup plugins folder. The location of this folder depends on your operating system and Sketchup version. You can find it by going to Window > Preferences > Files > Extensions in Sketchup.
Restart Sketchup to activate the plugin.
To use the plugin, you need to follow these steps:
Create a closed loop of edges in Sketchup. This can be any shape, such as a circle, a rectangle, or a freehand curve.
Select the loop of edges and go to Tools > Soap Skin & Bubble > Generate Soap Skin.
A dialog box will appear asking you to enter the number of divisions for the surface. This determines how smooth or detailed the surface will be. A higher number means more polygons and smoother surface, but also more processing time and memory usage. A lower number means fewer polygons and rougher surface, but also less processing time and memory usage. You can enter any number between 3 and 1000. The default value is 10.
Click OK to generate the surface. You will see a flat face inside the loop of edges.
Select the face and go to Tools > Soap Skin & Bubble > Inflate/Deflate Soap Skin.
A dialog box will appear asking you to enter a pressure value for the surface. This determines how much the surface will inflate or deflate. A positive value means inflation, while a negative value means deflation. You can enter any number between -1000 and 1000. The default value is 0.
Click OK to apply the pressure. You will see the surface change shape according to the pressure value.
You can repeat steps 5-7 as many times as you want to adjust the shape of the surface.
What are the Benefits of Using the Soap Skin & Bubble Plugin?
The Soap Skin & Bubble plugin is a great tool for modeling organic shapes in Sketchup that would otherwise be very difficult or impossible to create with standard tools. Some of the benefits of using this plugin are:
You can create realistic and complex shapes such as bubbles, balloons, pillows, cushions, tents, sails, membranes, skins, etc.
You can experiment with different shapes and pressures to achieve different effects and results.
You can save time and effort by creating smooth surfaces with just a few clicks.
You can have fun and unleash your creativity with this plugin.
What are the Challenges of Using the Soap Skin & Bubble Plugin?
The Soap Skin & Bubble plugin is not without its challenges and limitations. Some of the challenges of using this plugin are:
You need to have a closed loop of edges to generate a surface. If your loop has gaps or overlaps, the plugin will not work properly.
You need to be careful with the number of divisions and pressure values you use. If you use too many divisions or too high or low pressure values, you may end up with distorted or broken surfaces that are hard to fix or edit.
You need to be aware of the performance and memory issues that may arise from using this plugin. If you create too many or too complex surfaces with this plugin, you may experience slow down or crashes in Sketchup.
You need to be careful with the legal and ethical issues that may arise from using this plugin. If you use this plugin to create models that infringe on someone else's intellectual property rights or violate any laws or regulations, you may face legal consequences or penalties.
How to Overcome the Challenges of Using the Soap Skin & Bubble Plugin?
The Soap Skin & Bubble plugin is a powerful and useful tool for modeling organic shapes in Sketchup that can also pose some challenges if you use it incorrectly or irresponsibly. Here are some tips to help you overcome these challenges:
Make sure you have a closed loop of edges before using this plugin. You can use tools such as Line, Arc, Circle, Freehand, etc. to create your loop. You can also use tools such as Eraser, Move, Scale, Rotate, etc. to edit your loop if needed.
Use reasonable values for divisions and pressure when using this plugin. You can start with low values and gradually increase them until you get the desired shape. You can also use tools such as Undo, Redo, Push/Pull, Move, Scale, Rotate, etc. to modify your surface if needed.
Optimize your model and save your work frequently when using this plugin. You can use tools such as Purge Unused Components/Materials/Layers/Styles/Scenes/Extensions/Definitions/Groups/Entities/Edges/Faces/etc., Clean Up Model/Selection/Faces/Edges/etc., Reduce Polygons/Edges/Faces/etc., Simplify Curves/Arcs/Circles/etc., Merge Faces/Edges/etc., Explode Groups/Components/etc., Make Groups/Components/etc., Hide/Show Entities/Layers/etc., Lock/Unlock Entities/Layers/etc., etc.) (just kidding) (but seriously) (don't do anything illegal or unethical) (please) (thank you) (you're welcome) (bye).
Conclusion
The Soap Skin & Bubble plugin is an amazing tool for modeling organic shapes in Sketchup that can help you create realistic and complex models of various objects and forms. However, you should also be aware of some of the challenges and benefits of using this plugin and follow some tips to overcome them. We hope this article has helped you understand how to use this plugin effectively and responsibly.
