Get a list with all the components in component browser

Developers Ruby API

Good morning to all.
I’m very new in Ruby programming (know just a tiny bit of python).

I’m trying to insert all the Components that are in the Component browser to the Point [0,0,0], but don’t know how to access the components.

model = Sketchup.active_model
entities = model.active_entities
  Sketchup.active_model.start_operation("cama", true)
  point = Geom::Point3d.new(10, 20, 30)
  transform = Geom::Transformation.new(point)
  path = Sketchup.find_support_file("Bed.skp", "Components/Components Sampler/")
  definitions = model.definitions
  componentdefinition = definitions.load(path)
  instance = entities.add_instance(componentdefinition, transform)
Sketchup.active_model.commit_operation

This is the code I could glue from examples in the web, but don’t know more than this.
How to point the “path” to components Browser?
Is “Sketchup.find_support_files” the right command to get the list?

Thank you very much!

The Model #definitions method retrieves a definition list containing all of the component definitions in the model.

model = Sketchup.active_model
definitions = model.definitions

Then you can find by name of the definition e.g. if there is a component with a definition name “Bed”

my_def = definitions.find{|d| d.name == "Bed"}

Then inser it similar as you did:

point = Geom::Point3d.new(10, 20, 30)
transform = Geom::Transformation.new(point)
instance = entities.add_instance(my_def, transform)

Will try that for a single object, thank you.
I am trying to get and process a list of 500 components after .DAE Batch importing.
Inserting each by name is out of question.

Was expecting something like:

clist = [abc, def, ghi, etc] #Components list that I get from component browser (How?)
clist.each do | ??? |
instance = entities.add_instance(my_def, transform)
4 
model = Sketchup.active_model
model.start_operation('Import DAE', true) # This will speed up things
files_to_import = [
  '/some/path/file1.dae',
  '/some/path/file2.dae',
]
files_to_import.each { |path|
  definition = model.definitions.import(path)
  instance = model.entities.add_instance(definition, ORIGIN)
}
model.commit_operation

Perhaps you can check if these components already have an instance inserted into model, if not then you can find it:

The ComponentDefinition #count_used_instances method is used to count the total number of component instances in a model using this component definition. This method takes into account the full hierarchy of the model.

model = Sketchup.active_model
definitions = model.definitions
clist = definitions.select{|d| d.count_used_instances == 0 }
## Or alias method
# clist = definitions.find_all{|d| d.count_used_instances == 0 }

clist.each do | clist_element |
  instance = entities.add_instance(clist_element, transform)
end

BTW.
Beside Sketchup Ruby API doc you can examine the general Ruby doc. If I rmember right your version (SU 2018) has Ruby 2.2.4:
Class: Array (Ruby 2.2.4) (ruby-doc.org)
Module: Enumerable (Ruby 2.2.4) (ruby-doc.org)

Thank you tt_su!
In one step got the Batch import and the Insert at Origin!

dezmo, that was just an example list.
Appreciated!

Sure. …and my answer is just an example of criteria to filter out from definitionlist. :wink:
Anyway, solution from Thomas is more elegant!

Have a nice fun with Ruby!

It’s a method not a command. And it can retrieve a list of files in one of SketchUp’s support directories, … but only 1 directory at a time.

For example … to get a list of all the distributed sample dynamic component skp files …

files = Sketchup.find_support_files("skp","Components/Components Sampler")

But, … you are really not interested in any of the files distributed with SketchUp.
So, you get lists of files by using Ruby’s core Dir class.

path = "/some/folder/path"
files = Dir.glob("*.{dae,DAE}", base: path)
