Overview

The SketchupExtension class contains methods allowing you to create and manipulate SketchUp extensions. Extensions are Ruby scripts that can be loaded and unloaded using the Extension manager (Extensions panel of the Preferences dialog box). Generally you should register your ruby scripts as an extension to give SketchUp users the ability to disable it through the user interface.

The idea here is to take the ruby script that actually creates your functionality and place it in a folder somewhere outside of the /Plugins folder, most commonly a subdirectory like /Plugins/MyExtension. Then you create a new ruby script inside the /Plugins directory that will set up the extension entry and load your original script if the user has your extension turned on.

Here is an example extension loading script. For this example, the following code would be saved in /Plugins/StairTools.rb, and the actual plugin itself would live in /Plugins/StairTools/core.rb.

You can find two example extensions that ship with SketchUp, su_dynamiccomponents.rb and su_sandboxtools.rb, under the /Plugins/ folder.

Examples:

# Create an entry in the Extension list that loads a script called
# core.rb.
require 'sketchup.rb'
require 'extensions.rb'

stair_extension = SketchupExtension.new('Stair Tools", "StairTools/core.rb')
stair_extension.version = '1.0'
stair_extension.description = 'Tools to draw stairs automatically.'
Sketchup.register_extension(stair_extension, true)

Version:

  • SketchUp 6.0

Constructor Details

#initialize(title, path) ⇒ Sketchup::Extension

Note:

It is recommended to omit the file extension provided in the path argument. SketchUp will resolve the file extension to .rbe, .rbs or .rb.

The new method is used to create a new SketchupExtension object. Note that once the extension object is created, it will not appear in the Extension Manager dialog until your register it with the Sketchup.register_extension method.

Examples:

# Create an entry in the Extension list that loads a script called
# core.rb.
extension = SketchupExtension.new('Stair Tools', 'StairTools/core')

# Then be sure to register it. By passing a 2nd param of true, you're
# telling SketchUp to load the extension by default.
Sketchup.register_extension(extension, true)

Parameters:

  • title (String) —

    The name of the extension

  • path (String) —

    The relative path to the script that loads your plugin.

Version:

  • SketchUp 6.0

Instance Method Details

#check ⇒ Boolean

Loads the extension, meaning the underlying ruby script is immediately interpreted. This is the equivalent of checking the extension’s checkbox in the Preferences > Extensions list.

Examples:

# This will register the extension, a necessary step for it to appear
# in SketchUp's Preferences > Extensions list
ext_c = SketchupExtension.new('Stair Tools C', 'StairTools/core.rb')
Sketchup.register_extension(ext_c, false)

# And this will load the extension.
ext_c.check

Returns:

  • (Boolean) —

    whether the load succeeded

Version:

  • SketchUp 8.0 M2

    the Extension copyright

#uncheck ⇒ Boolean

Unloads the extension. This is the equivalent of unchecking the extension’s checkbox in the Preferences > Extensions list.

Examples:

# This unloads all extensions. The next time SketchUp starts, none of
# the extensions will be active.
Sketchup.extensions.each { |extension|
  extension.uncheck
}

Returns:

    whether the unload succeeded
