Delete All Hidden Geometry (Including Hidden Tags)

This script permanently deletes all hidden geometry in a SketchUp model, including geometry on hidden tags and within nested groups or components.

Broken button... I'll fix it eventually...

require 'set'

# Function to delete all hidden entities recursively, including those in groups and components

def delete_hidden_entities(entities, processed = Set.new)

entities.each do |entity|

# Skip already processed entities to avoid infinite loops

next if processed.include?(entity)

processed.add(entity)

# Delete the entity if it's hidden

if entity.respond_to?(:hidden?) && entity.hidden?

entity.erase! # Permanently delete the entity

end

# Recursively process groups and components

if entity.is_a?(Sketchup::Group) || entity.is_a?(Sketchup::ComponentInstance)

delete_hidden_entities(entity.definition.entities, processed)

end

# Main script execution

model = Sketchup.active_model

if model.nil?

UI.messagebox("No active SketchUp model found. Please open a model and try again.", MB_OK)

else

# Start operation to improve performance

model.start_operation("Delete Hidden Geometry", true)

# Make all tags visible to access hidden geometry on hidden tags

layers = model.layers

layers.each { |layer| layer.visible = true }

# Delete all hidden entities in the model

delete_hidden_entities(model.entities)

# Commit operation

model.commit_operation

# Notify user

UI.messagebox("All hidden geometry has been successfully deleted, including geometry on hidden tags!", MB_OK)

end

Checks Visibility of All Tags:Sets all tags to visible so that hidden geometry on hidden tags can be processed.
Deletes Hidden Geometry:Recursively iterates through all entities in the model and deletes any entity that is hidden.
Handles Nested Entities:Processes nested groups and components to ensure no hidden geometry is missed.

Copy and paste this script into SketchUp’s Ruby Console or save it as a .rb file.
Run the script in your SketchUp model.
The script will delete all hidden geometry, including entities on hidden tags.

Permanent Deletion: This script will permanently delete all hidden geometry. Ensure that you save your model or make a backup before running the script.
Tags Are Made Visible: After running the script, all tags will remain visible.
