Remove and purge hidden components.

TNTDAVID

**Hello,

I'm currently finalizing Click-Cuisine 2.

In order to offer a complete tool, it is essential for me to offer Click-Cuisine 2 specific functions.

**Thanks to the many subjects opened in this formum and your help, Click-Cuisine allows to:
**

Remove the included dynamic thumbnails of each furniture through their definitions and purge their materials.
Purge materials not used by Click-Cuisine furniture 2.

To finish the functions of cleaning, I have to write 2 methods:

Purge the hidden dynamic components in all components with the "IKEA" definition.
Remove all dynamic attributes of components with the "IKEA" definition.

I want to target the components with the IKEA definition, so as not to involuntarily affect other dynamic components.

Any help from you will be greatly appreciated.

Cordially

**Hello,

After some research, I found this sample code:

Sketchup.active_model.definitions.each {| d | d.entities.to_a.each {| e | e.erase! if e.hidden?}}

The problem with this example is that hidden lines are deleted.

I only want to remove he hidden components.

thank you in advance for your help

Perhaps add && e.is_a?(SketchUp::ComponentInstance) to the if test? Also note that it would be good to check whether e.respond_to?(:hidden?) before doing e.hidden? since not all Entities support hidden, and if your code ever encounters one of these it will throw an exception.

TIG

Consider this with 'grep'...

Sketchup.active_model.definitions.each{|d|d.entities.grep(Sketchup;;ComponentInstance).each{|e|e.erase! if e.hidden?}}

This will include only nested instances found inside definition's and then erase them, if they are hidden.

TNTDAVID

Thank you TIG and slbaumgartner

The TIG example works perfectly.

**Is it possible to purge hidden components inside components with the IKEA definition only?

This will avoid affecting all the file to target only the 3D models proposed by Click-Kitchen 2.

For example:

Method A selects all components with the IKEA definition.

# Method A
m=Sketchup.active_model;s=m.selection;m.definitions.each{|d|s.add d.instances if d.name=~/#{"IKEA"}/}

Method B searches for hidden components inside the selection and deletes them.

To write Method B, I need your help.

Thank you

(1) Why are you putting quotes around IKEA ? (The regular expressions are themselves specially treated double quoted strings.)

Dan Rathbun

(2) You are wasting time pushing objects into the selection set.
This is not necessary in order to modify them.

(3) Instances do not "own" any nested components. Definitions own nested objects.
So you should be collecting a set of IKEA definitions, and then searching the definitions entities collection(s) (in that set,) for hidden objects.
When a definition has a child object that is hidden, it will be hidden in ALL of the definition's instances.
When you delete a hidden object from a definition, ALL of it's instances will have that child object deleted.

TNTDAVID

**I'm not sure I understand all of your logical reasoning Dan.

I want to delete hidden definitions and not instances.

For example:

Dynamic Cabinet consists of a Drawer and a Door.

The Drawer is hidden by its "Hidden" attribute.

The Gate is visible by its "Hidden" attribute.

Both have instances "Handles" in "sub-component".

The method must delete the "Drawer" definition because it is hidden.

Thus, only the "Handles" instance of the drawer will be deleted without affecting the same instances of the door.

@tntdavid said:

I want to delete hidden definitions and not instances.

Definitions are not hidden in the model, because they do not exist in the model entities collection (only instances do.)

When a definition is "hidden", it does not appear in the Components Browser list, but still is a member of the model's DefinitionList collection.

TIG

As Dan says don't mess on with the selection-set...
IF you actually need to collect things for later use, consider using an array [] or a hash {}...
But that is NOT needed here...
How about this ?

Sketchup.active_model.definitions.each{|d|next unless d.name=~/IKEA/; d.entities.grep(Sketchup;;ComponentInstance).each{|e|e.erase! if e.hidden?}}

This deletes all nested entities within any definition named /IKEA/, if they are hidden...

TNTDAVID

**Sorry Dan, I mixed brushes between definitions and instances ...

It's wonderful TIG, your code meets 100% to my needs.

I want to be very careful with the selections or deletes, for this reason your example is perfect.

The code below removes all attributes of all dynamic components present in a SketchUp file.

m=Sketchup.active_model;m.start_operation("unDC");m.definitions.each{|d|d.attribute_dictionaries.delete("dynamic_attributes") if d.attribute_dictionaries and d.attribute_dictionaries["dynamic_attributes"];d.instances.each{|i|i.attribute_dictionaries.delete("dynamic_attributes") if i.attribute_dictionaries and i.attribute_dictionaries["dynamic_attributes"]}};m.commit_operation

How to adapt this code so that it only deletes the dynamic attributes of all nested entities in the named definitions / IKEA / ?

Thank you**

TIG

Adjust ...;m.definitions.each{|d|d.attribute_dictionaries...
to something like this:
...;m.definitions.each{|d|**next unless d.name=~/IKEA/;**d.attribute_dictionaries...
To limit the action to /IKEA/ named definitions...

TNTDAVID

**

Wonderful! Your example works TIG, for instances with IKEA definitions:**

m=Sketchup.active_model;m.start_operation("unDC");m.definitions.each{|d|next unless d.name=~/IKEA/; d.attribute_dictionaries.delete("dynamic_attributes") if d.attribute_dictionaries and d.attribute_dictionaries["dynamic_attributes"];d.instances.each{|i|i.attribute_dictionaries.delete("dynamic_attributes") if i.attribute_dictionaries and i.attribute_dictionaries["dynamic_attributes"]}};m.commit_operation

Is it possible to purge dynamic attributes of nested components in instances with IKEA definitions?

Thank you

TNTDAVID

**Bonjour,

Votre solution TIG pour supprimer les composants masqués à l'intérieur des définition IKEA, fonctionne très bien!

Sketchup.active_model.definitions.each{|d|next unless d.name=~/IKEA/; d.entities.grep(Sketchup;;ComponentInstance).each{|e|e.erase! if e.hidden?}}

A l'intérieur de la définition IKEA, il y a beaucoup d'autres définitions qui ont des sous composants masqués.

Est-il possible de supprimer tous les composants masqués pour toutes les définitions présentes dans les meubles IKEA ?

L'idéal serait de na pas avoir à citer toutes les définitions existant dans les meubles IKEA.

Merci**

TNTDAVID

**Little reminder:

It is possible to remove all hidden components of a SketchUp file, with this method:

Sketchup.active_model.definitions.each{|d|d.entities.grep(Sketchup;;ComponentInstance).each{|e|e.erase! if e.hidden?}}

It is possible to remove all hidden components with the name of a definition, with this method:

Sketchup.active_model.definitions.each{|d|next unless d.name=~/IKEA/; d.entities.grep(Sketchup;;ComponentInstance).each{|e|e.erase! if e.hidden?}}

How to remove all hidden components and sub-components in a selection?

Thank you

TNTDAVID

**I finally found how to remove hidden sub-components from a selection:

mod = Sketchup.active_model
sel = mod.selection
sel.grep(Sketchup;;ComponentInstance).each{|s|;
s.definition.entities.grep(Sketchup;;ComponentInstance).each{|e|e.erase! if e.hidden?}}

The problem is that only the first level of nesting is removed by the method.

I will continue to search in esperente found the solution.

See you

**I can select all the definitions by their names and apply a cleaning of hidden components:


def methode1 ### select components and sub-components with the name of the definitions.	
    ["IKEA","DOOR","DRAWER","HANDLES"].each{|name|
    match = /#{name}/i	
    m=Sketchup.active_model;
    s=m.selection;
    m.definitions.each{|d|s.add d.instances if d.name =~ match }}
    end	
	
def methode2 ### remove hidden components in the selection		
    Sketchup.active_model.selection.grep(Sketchup;;ComponentInstance).each{|s|
    s.definition.entities.grep(Sketchup;;ComponentInstance).each{|e|e.erase! if e.hidden?}}
    end
		
def methode_end 
    methode1
    methode2	
    end

I'm progressing but this solution is not great.

Any help would be highly appreciated.**

**They always told me to be persistent and I thank all those who gave me this advice.

Here is the method to remove all hidden sub-components in a parent component:


def supprimer_tous_les_sous_composants_selection(instance)
    children = instance.definition.entities.select { |e| e.respond_to?(;definition) }
    children.each { |c| supprimer_tous_les_sous_composants_selection(c);
    c.erase! if c.hidden?
    }
    end
	
    supprimer_tous_les_sous_composants_selection(Sketchup.active_model.selection.first)

Here is the method to remove all the dynamic attributes of all the components present in a selection:


def selectionner_tous_les_sous_composants_selection(instance)
    children = instance.definition.entities.select { |e| e.respond_to?(;definition) }
    instance.model.selection.add(children)
    children.each { |c| selectionner_tous_les_sous_composants_selection(c);
    }
    end	
	
def supprimer_tous_les_attributs_dynamiques_selection
    mod = Sketchup.active_model
    sel = mod.selection
    sel.each{|s|s.definition.attribute_dictionaries.delete("dynamic_attributes");
  sel.grep(Sketchup;;ComponentInstance).each{|i|i.attribute_dictionaries.delete("dynamic_attributes")}}
    end	
	
def desactiver_toutes_les_selections
    mod = Sketchup.active_model
    ent = mod.active_entities
    sel = mod.selection
    instances = sel.grep(Sketchup;;ComponentInstance)
    sel.clear
    end		
	
selectionner_tous_les_sous_composants_selection(Sketchup.active_model.selection.first)
supprimer_tous_les_attributs_dynamiques_selection
desactiver_toutes_les_selections

You can test these methods directly with the ruby console, after selecting a dynamic component.

You will notice that all hidden components and dynamic attributes will be removed, even if they are nested at multiple levels.

Thank you to everyone who helped me.

See you

David**
