Component names

[chrisglasier]

As you can see from this:

I can retrieve the names of scenes and layers. I can also seem to do things with properties to save, views, and styles. Collections and groupings are something for later. But I can't get to grips with retrieving component names. For example, what is bed.skp all about here?

path = Sketchup.find_support_file "Bed.skp", "Components/Components Sampler/" model = Sketchup.active_model definitions = model.definitions componentdefinition = definitions.load path name = componentdefinition.name

I just want to make an array of each of the names that appear in the entity info box.

Any help yet again gratefully received!

Looks great; many thanks Chris

Sorry one more bit of bother

Sorry typo by me...

insts=[];model.active_entities.each{|inst|insts.push(inst)if inst.typename=="ComponentInstance"}

I usually use 'e' as my block variable BUT changed it to 'inst' to help you BUT forgot to change one !!! It's inst.typename... NOT e.typename... I've edited the original too...

[TIG]

To do stuff on the model's content you need to find the placed component instances...

insts=[];model.active_entities.each{|inst|insts.push(inst)if inst.typename=="ComponentInstance"}

To find an instance's definition name use

inst.definition.name

, to find its individual instance name (you can also give each instance its own name using entity info...) you can use

inst.name

.
To do stuff on the model's data-base definitions etc use

defns=model.definitions;defns.each{|defn|insts=defn.instances;insts.each{|inst|###etc###} }

Again defn.name or inst.name to give you their names...
You can also find an instance's unique enduring ID if needed...
Groups work slightly differently... but similar enough...

No sorry please! (Chinglish)

Yes I thought that but thought maybe it was some special thing when I did not get the answer I was expecting with inst. I thought active_entities was the same as select all, but I see now it's not ... so I get all components rather than just those in the scene (like outliner does). If you have time to figure that out for me that would be great ...

model.selection

gives only currently selected entities

model.active_entities

gives only entities that are currently 'active' i.e. editable - e.g. inside a group edit when you would want to ignore other external things

model.entities

gives all of the model's entities, even those currently not editable.

It is often best to use 'active_entities' as it is equal to 'entites' if you are currently at the base model level but it's limited to the edited instance-definition/group's entities if you are not. If you use 'entities' and were to add something to them it is put at the base level - and it might then be outside of the group edit and lead to confusion/splats, whereas with 'active_entities' it is put at the lowest level in that edit, also note that definition.entities or group.entities returns the specified definition's or group's entities etc...

I think in your case 'model.entities' is what you want ?

[chrisglasier]

Ok thanks but it's not quite there yet I'm afraid, and this is of course a very important part of the whole.

If I select all from the edit menu, and then use model.selection instead of active_entities I can abstract just the instances that show in that scene (page). Is it possible to "ruby" the select all?

[TIG]

Use 'model.entities' and filter it thus ?

insts=[]
model.entities.each{|e|insts.push(e)if e.typename=="ComponentInstance"}
### insts is then an array containing all of the instances in the model
### you could also add names, groups etc

If you want only things that are active then use 'model.active_entities'.
I'm not sure you can get things only if they are visible in a scene ?
Do you mean not 'behind' the camera ?
You can of course get if they are hidden or on off-layers etc and remove them from the array...

That's it ... but of course?? I'll get back on it tomorrow. In the meantime thanks for your help.

Here's the result:

# Lists components and groups (with hidden status) in a scene
	
@dlg.add_action_callback("findComponents") {|d, p|
	
model = Sketchup.active_model
entities = model.active_entities

a = 0
array = []

entities.each do |entity|

if  entity.class == Sketchup;;Group || entity.class == Sketchup;;ComponentInstance 

if entity.layer.visible?

array[a] = []

if  entity.class == Sketchup;;ComponentInstance 
array[a][0] = entity.definition.name
end

if  entity.class == Sketchup;;Group
array[a][0] = entity.name
end

array[a][1] = entity.hidden?

array[a] = array[a].join(",")

a+=1

end  #if class
end  # if visible
end  #loop

array = array.join(";")

cmd = "receiveComponents('#{array}');"
@dlg.execute_script (cmd)      }

Tally ho!
