Overview

Note:

By default Extension Warehouse encrypts extensions and convert .rb files to .rbe files. Omit the file extension to let SketchUp look for both.

A SketchUp extension is a piece of software that extends the capabilities of SketchUp. It could be a new drawing tool, a content library or a way to automate a tedious and time consuming task.

The SketchupExtension handles the extension metadata, such as name, author and version, as well as a path to the main Ruby file with the actual functionality you want to add.

Examples:

require 'sketchup.rb'
require 'extensions.rb'

stair_extension = SketchupExtension.new('Stair Tools', 'stair_tools/core')
stair_extension.version = '1.0.0'
stair_extension.description = 'Tools to draw stairs automatically.'
Sketchup.register_extension(stair_extension, true)

Version:

  • SketchUp 6.0

Constructor Details

.new(title, path) ⇒ SketchupExtension

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.
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 Extension Manager.

Examples:

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

# And this will load the extension.

Returns:

  • (Boolean) —

    whether the load succeeded

Version:

  • SketchUp 8.0 M2

#extension_path ⇒ String

The #extension_path method returns the file system path to the extension's outer rb file.

Returns:

#load_error ⇒ Exception?

Return the Ruby load error for an extension that failed to load.

Examples:

# broken/broken_file.rb
raise "This file raises an exception"

# broken.rb
extension = SketchupExtension.new("Broken Extension", "broken/broken_file")
extension.version = "1.0.0"
extension.description = "This extension's has an error."
Sketchup.register_extension(extension, true)

extension.load_error
# => RuntimeError

Version:

  • SketchUp 2026.2

#uncheck ⇒ Boolean

Unloads the extension. This is the equivalent of unchecking the extension's checkbox in the Extension Manager > Extensions list.

Note that technically the extension is not "unloaded" in the sense that it stops running during the current SketchUp session, but the next time the user restarts SketchUp, the extension will not be active.

Examples:

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

Returns:

  • (Boolean) —

    whether the unload succeeded

Version:

  • SketchUp 8.0 M2

#version_id ⇒ String

The #version_id method returns the Extension Warehouse Version ID string.

Returns:

  • (String) —

    the Extension Warehouse Version ID string

Version:
