Replace components

liquid98

Hi,

I have this ruby script to replace a component with an other:

` require 'sketchup'

module Swapi

def Swapi.main
	
	
model = Sketchup.active_model
    entities = model.active_entities
    selection = model.selection

newDef = model.definitions.load("c:\new.skp")
oldDef = model.definitions['old']
oldDef.instances.each { |old_inst|
t = old_inst.transformation
ents = old_inst.parent.entities
ents.add_instance(newDef, t)
old_inst.erase!
}

end




  unless file_loaded?( __FILE__ )
    UI.menu("Plugins").add_item("swap") {Swapi.main}
  end

end # module

file_loaded( __FILE__ )`

But it doesn't work, can someone help me out?.

And an other question: Is it possible to insert a component from a file wich contains several
different components?

Thnx

TIG

Assuming that you have the 'old' compo etc...

###...
newDef = model.definitions.load("c;\\new.skp")
oldDef = model.definitions['old']
oldDef.instances.each{|old_inst|old_inst.definition=newDef}
###...

is much easier...
Also note that you must use \ for a \ in the file path inside "" otherwise 'newDef' is returned as 'nil'.
In the Ruby Console set model=Sketchup.active_model and then copy paste that one line model.definitions.load("c:\new.skp") and then model.definitions.load("c:\\new.skp") to see what each returns...

Thank you TIG

still learning... Now it works

Is it also possible to do this:

newDef = model.definitions.load("c;\\new.skp(componentX)")

To load 'componentX' from c:\new.skp assuming that new.skp contains several
components among which there is a component called componentX?

Or do I have to do something with the model.definitions belonging to new.skp?
Making a list and choose from there? I really don't have a clue..

Please help

The whole 'new.skp' will load with whatever subcomponents it might have.
If you only want componentX you have to either have split it out by hand earlier and use that, OR import all of 'new.skp' and then manipulate that. For example, after importing new.skp you have a component definition called 'new' and a definition object pointing at it called 'newDef' [as you coded], you can now iterate through the entities inside newDef thus:

<span class="syntaxdefault"></span><span class="syntaxcomment">###...<br /></span><span class="syntaxdefault">defn</span><span class="syntaxkeyword">=</span><span class="syntaxdefault">nil<br />newDef</span><span class="syntaxkeyword">.</span><span class="syntaxdefault">entities</span><span class="syntaxkeyword">.</span><span class="syntaxdefault">each</span><span class="syntaxkeyword">{|</span><span class="syntaxdefault">e</span><span class="syntaxkeyword">|</span><span class="syntaxdefault">defn</span><span class="syntaxkeyword">=</span><span class="syntaxdefault">e if e</span><span class="syntaxkeyword">.class==</span><span class="syntaxdefault">ComponententInstance and e</span><span class="syntaxkeyword">.</span><span class="syntaxdefault">name</span><span class="syntaxkeyword">==</span><span class="syntaxstring">"componentX"</span><span class="syntaxkeyword">}<br /></span><span class="syntaxdefault">if defn<br />  </span><span class="syntaxcomment">### do something with 'componentX' or 'newDef'### e.g.<br /></span><span class="syntaxdefault">  inst</span><span class="syntaxkeyword">=</span><span class="syntaxdefault">entities</span><span class="syntaxkeyword">.</span><span class="syntaxdefault">add_instance</span><span class="syntaxkeyword">(</span><span class="syntaxdefault">defn</span><span class="syntaxkeyword">,</span><span class="syntaxdefault"> Geom</span><span class="syntaxkeyword">;;</span><span class="syntaxdefault">Transformation</span><span class="syntaxkeyword">.new(</span><span class="syntaxdefault">ORIGIN</span><span class="syntaxkeyword">))<br /></span><span class="syntaxdefault">  xdef</span><span class="syntaxkeyword">=</span><span class="syntaxdefault">inst</span><span class="syntaxkeyword">.</span><span class="syntaxdefault">definition<br />  inst</span><span class="syntaxkeyword">.</span><span class="syntaxdefault">erase</span><span class="syntaxkeyword">!<br /></span><span class="syntaxdefault">  </span><span class="syntaxcomment">### moves xdef into mainstream defs list outside of nested 'new' entities [name will probably adjust too?]<br /></span><span class="syntaxdefault">  </span><span class="syntaxcomment">###...<br /></span><span class="syntaxdefault">end</span><span class="syntaxcomment">#if<br />###...<br /></span><span class="syntaxdefault"> </span>
