Redraw a dynamic component

TIG

The attributes belong to the instance's defintion NOT the instance.
You mess up trying to set things to the instance, NOT the definition !
Try substituting something like...

i.definition.set_attribute('dynamic_attributes', 'teste', '1')
$dc_observers.get_latest_class.redraw_with_undo(i)

Please learn the difference between a definition and its instance !!!!!

This still does not work for components without attributes:

Sketchup.active_model.selection.grep(Sketchup;;ComponentInstance){|i|
next unless i.definition.attribute_dictionaries["dynamic_attributes"]
i.definition.set_attribute('dynamic_attributes', 'teste', '1')
$dc_observers.get_latest_class.redraw_with_undo(i)
}

TIG

WTF !
You really must learn basic principles...
consider this:


Sketchup.active_model.selection.grep(Sketchup;;ComponentInstance){|i|
###next unless i.definition.attribute_dictionaries["dynamic_attributes"]
i.definition.set_attribute('dynamic_attributes', 'teste', '1')
$dc_observers.get_latest_class.redraw_with_undo(i)
}

The added ### skips the check for the dictionary [ which you do NOT need ! ]... so IF a definition does NOT have that dictionary set then it makes it anyway !!!!!!

**OK TIG, I understand!

The Ruby is very wide and has many instructions such as:

!,&&,||,and,box,else,elsif,eql?,equal,if,then,not,gold,require,unless,wheen,true, false...

I had not yet read "unless".

I realize that it takes many years of Ruby to totally understand him master it.

As I learn according to my needs, this undoubtedly slows down my general understanding of ruby.

Promised, next time I would make more effort with your examples before publishing it does not work.

Ps: Your solution works wonderfully TIG

Thanks a lot for your help.

**Hello,

I now want to refresh the visible dynamic components.

If not, the answer must be "nil".

The methde below works for components that are not nested:

m=Sketchup.active_model;
s=m.selection;
m.definitions.each{|d|s.add d.instances if d.name=~/#{"BOUTON"}/}
s.grep(Sketchup;;ComponentInstance){|i|
next if i.hidden?
$dc_observers.get_latest_class.redraw_with_undo(i)
}

Oddly if the components with the "BOUTON" definitions, are nested in another component, they will be considered as visible even if they are hidden.

Do you know what is the problem?

Thank you**

Please stop adding entities into the selection.
What happens if it already contains some selected entities ?
You haven't cleared it ??
Also these additions might not be in the current context and cause various issue down the line...

Simply create an empty array and add entities to that if they meet a certain test.
e.g.

def handlesCI(ents)
  array = []
  ents.grep(Sketchup;;ComponentInstance).each{|e| ### collect only visible instances
    next unless e.visible?
    array << e if e.definition.name =~ /#{"HANDLES"}/
    handlesCI(e.definition.entities) ### repeat for nested entities in visibles
  }
  array.each{|i| ### process this array of instances
    $dc_observers.get_latest_class.redraw_with_undo(i)
  }
end

TNTDAVID

**Your method works TIG, but it does not keep the "Handles" definitions selected.

The goal is to update all Invisible Handles, then select any definition "Handles" without visibility restrictions.**

TNTDAVID

**Here I am in a paradox!

If I apply your TIG method, the handles selected in Method 2 will also be redrawn.

 
def methodeTIG(ents)
    sel = Sketchup.active_model.selection
    array = []
    ents.grep(Sketchup;;ComponentInstance).each{|e| ### collect only visible instances
    next unless e.visible?
    array << e if e.definition.name =~ /#{"HANDLES"}/
    methodeTIG(e.definition.entities) ### repeat for nested entities in visibles
    }
    array.each{|i| ### process this array of instances
    $dc_observers.get_latest_class.redraw_with_undo(i)
    }
    end  	  

def methode2(ents)
    sel = Sketchup.active_model.selection
    ents.each do |e|
    if e.is_a? Sketchup;;ComponentInstance
    sel.add e if e.definition.name=~/#{"HANDLES"}/
    methode2(e.definition.entities)
    end
    end
    end

def methode_end
    methodeTIG(instances)
    methode2(instances) ### The handles of this method are drawn by the methodTIG! 
    end

How can I avoid this?

Thank you**

**I solved the problem of my previous post!

Now, I'm facing another problem that is much more difficult to solve.

The code below adds an attribute to all the "Handles" definitions that are visible in the components being selected.


def handlesCI(ents)
    sel = Sketchup.active_model.selection
    ents.each do |e|
    if e.is_a? Sketchup;;ComponentInstance
    sel.add e if e.definition.name=~/#{"HANDLES"}/
    handlesCI(e.definition.entities)
    sel.grep(Sketchup;;ComponentInstance){|i|
    next unless i.visible?
    i.set_attribute 'dynamic_attributes','attribut', '1'
    }
    end
    end
    end

This method does not work to refresh only visible components.


def handlesCI(ents)
    sel = Sketchup.active_model.selection
    ents.each do |e|
    if e.is_a? Sketchup;;ComponentInstance
    sel.add e if e.definition.name=~/#{"HANDLES"}/
    handlesCI(e.definition.entities)
    sel.grep(Sketchup;;ComponentInstance){|i|
    next unless i.visible?
    $dc_observers.get_latest_class.redraw_with_undo(i)
    }
    end
    end
    end

I need your help to understand the problem.

Thank you

**I ended up bypassing the problem by selecting a different definition than "handles" in method 2.

I asked to select the IKEA definition, which corresponds to the furniture that contains the facades and the handle inside.


def ikeaCI(ents)
    sel = Sketchup.active_model.selection
    ents.each do |e|
 if e.is_a? Sketchup;;ComponentInstance
    sel.add e if e.definition.name=~/#{"IKEA"}/
    ikeaCI(e.definition.entities)
    end
    end
    end

This is possible because I specified the definition of the highest components of the hierachie.

Is it possible to select the highest components of the hierarchy without specifying the name of that definition?

Thank you TIG for your method that allows me to redraw the visible handles. **
