How Do I Use Ruby in SketchUp?

by

SketchUp is a powerful 3D modeling software that allows you to create and manipulate 3D models with ease. While SketchUp offers a wide range of tools and features, you can enhance your workflow by using Ruby scripting.

With Ruby, you can automate repetitive tasks, extend SketchUp’s functionality, and create custom tools. In this tutorial, we will explore how to use Ruby in SketchUp.

Installing Ruby Console+

To start using Ruby in SketchUp, you need to install the Ruby Console+ extension. This extension provides an interactive console where you can write and execute Ruby code directly within SketchUp.

  • Step 1: Open SketchUp and go to the “Extensions” menu.
  • Step 2: Select “Extension Warehouse” from the drop-down menu.
  • Step 3: In the Extension Warehouse window, search for “Ruby Console+.”
  • Step 4: Click on the “Install” button next to the extension.

The Ruby Console+ extension will now be installed in SketchUp, and you can access it through the “Extensions” menu.

Using the Ruby Console+

The Ruby Console+ provides a convenient way to interact with SketchUp using Ruby code. You can access it by going to “Extensions” > “Ruby Console+” in the menu.

Evaluating Code

To evaluate a single line of code in the console, simply type it into the input field at the bottom and press Enter. The result will be displayed in the output area above.

Note: Make sure to select objects before executing commands that require a selection. Otherwise, the command will return an error.

Writing Scripts

For more complex tasks, you can write scripts in the Ruby Console+. Scripts are sets of instructions that can be executed together. To write a script:

  1. Step 1: Click on the “New Script” button in the toolbar.
  2. Step 2: Enter your code in the editor window that appears.
  3. Step 3: Click on the “Run” button to execute the script.

You can also save and load scripts using the corresponding buttons in the toolbar.

Accessing SketchUp API

Ruby scripting in SketchUp is made possible by its powerful API (Application Programming Interface). The API provides a set of classes and methods that allow you to interact with SketchUp’s objects and features programmatically.

To access the SketchUp API, you can use the following syntax:


Sketchup::API.method_name

This allows you to call various methods provided by the SketchUp API to manipulate objects, create geometry, apply materials, and more.

Conclusion

Ruby scripting in SketchUp opens up a world of possibilities for extending its functionality and automating repetitive tasks. With Ruby Console+, you can evaluate code, write scripts, and access the SketchUp API with ease.

By harnessing this power, you can take your modeling workflow to new heights. So go ahead and dive into Ruby scripting in SketchUp!
