Auto-naming plugin ?

Jim

Have a look at TBD's numb and/or numb e plugins.

are they all pre-made groups. or do you make them?

herr_inspektor

Thanks to both of you for your answers!

@jim : i'll check your links soon as I get my computer back!

@driven : i create these groups myself, why ?

Hi all,

Sorry for updating this topic after such a long time, but I've just started again working on my project. Thanks for your help Jim, those plugins helped me understand about Sketchup scripts !

The only thing here is that I'd like to keep track of my variables between each time I launch the script. So here's what I did :

I created a first script that generates a text file with values in it, and then a second script that :

Parses this text file
Puts variables inside a "naming convention"
Names the group I've selected according to this naming convention
Increments the variable
Updates the textfile

Thing is, I'd like to avoid using a text file : if the person using my script gives his sketchup file without this textfile, then all previous work would be lost. Is there a way I could store values somewhere in the program and use them as I want ?

I thought about creating "invisible groups" and use their names as data storage, but I don't know if it's a good practice !

If you have any idea please let me know !

Thanks !

It would probably be best to add a custom attribute-dictionary to the SKP itself [ Sketchup.active_model.set_attribute(dictionary_name, key, value)].

You would then use Sketchup.active_model.get_attribute(name, key, default_value) to read the last value saved, and then later on you would use Sketchup.active_model.set_attribute(name, key, current_value) to replace the key with the current value.

Provided that the model has been saved then its SKP will contain these latest values when it is reopened later, even if it were copied onto another computer...

You can store many kinds of value as a key=value attribute, in your own named attribute-dictionary.
For example - Float/Integer/Length, String, Boolean[true/false], Array of any of these...

These key+values are saved as SKP specific records, I expect that is what you'll want... but if you want to have a set of key+values that apply to ALL SKPs. then you can consider the use of Sketchup.read_default and .write_default to save string data to the Registry - but remember that the data is then specific to that User on that PC, and does NOT pass on with each SKP - unless you also write those very same attributes to each SKP too, and code so that if there are no Registry entries, then the SKPs values are used instead - and the PC's Registry entries and all SKPs values are thereafter kept in sync ?

Wow, thanks for this very clear answer TIG, didn't know it was possible to add a dictionary to the SKP itself !

I'll try this when I get back home, thank you again !

EDIT : That's perfect, it works as expected ! Thanks !

Sorry again for double post, but there's something strange going on with my script.

It works fine ... once
I created the dictionnary as you suggested, and it's fine, I can read from it, name my group according to it and then increment but only one time.

It seems like the incrementation is not even executed the second time. Here's what I have :

` # Read data from the dict
data1 = Sketchup.active_model.get_attribute "NAME", "data1"
data2 = Sketchup.active_model.get_attribute "NAME", "data2"
data3 = Sketchup.active_model.get_attribute "NAME", "data3"
data4 = Sketchup.active_model.get_attribute "NAME", "data4"

Name the selected group according to the dict

as.each {|g|
Sketchup.active_model.selection.clear
Sketchup.active_model.selection.add(g)
g.name = "#{data1} #{data2} #{data2} #{data3}"
Sketchup.active_model.selection.clear
}

Write in the dict with an incremented variable

Sketchup.active_model.set_attribute "NAME", "data4", "#{data4 + 1}"`

I also tried creating a variable newdata4, increment it with data4 += 1 and then update the dict with this variable, but it doesn't work either

How could this work once but not twice ?

Thanks in advance !

You need to make things into say an integer - they are all strings...
model = Sketchup.active_model
Ensure data4 has a value:
data4 = model.get_attribute("NAME", "data4", "1").to_i
[that returns an integer 1 ]
Then ensure something is set/saved:
Sketchup.active_model.set_attribute("NAME", data4.to_s)
Then use the integers, including data4 to form the name:
g.name = "#{data1} #{data2} #{data3} #{data4}"
...and later increment the references and save them...
model.set_attribute("NAME", "data4", "#{data4 + 1}")

Incidentally 'NAME' is not a very unique name for a registry entry... can you use your Plugin's name - like "Seb_Name"

herr_inspektor

Thanks TIG ! That's perfect !
I don't know why but I thought Ruby would handle it automatically !

TIG

You see to want all integers so turning them from integers to strings and back again looks logical...
Then you can use +1 to increment the integers...

BUT if you wanted 'combined references' you can use say:
data = "A01"
Then later increment the string thus:
data.next!
which gives "A02"
The Ruby method .next increments strings, so x="A"; x.next!; x; "B" etc... .next returns the string incremented but leaves the original reference unchanged, adding the ! as in .next! also increments the reference itself.
