Script to bring all components from library into SU model

TIG

Use a simple
skps.each{|skp|defs.load(skp)}
which loads the skps into the definitions-list.
If you want to place instances of the definitions into the model you need to decide where the go.
Piling them all at the origin seems a bit silly?
How will you decide where they go ?
Let's assume they are added in a line from the origin incrementing in the x by 1m...
pt = Geom::Point3d.new(0,0,0)
You've just added the definitions and we know how many were added (skps.length), therefore we can get the new ones thus:
newdefs = defs.to_a[(defs.length - skps.length)..-1]
Now we add the instances to the model.
newdefs.each{|defn| tr=Geom::Transformation.new(pt) model.entities.add_instance(defn, tr) pt.x=pt.x+1.m }
This shifts 'pt' to the right 1m each time...

Hi TIG
Im still getting a syntax error on this Im afraid. Below is everything that is listed in the console when i copy and paste the lines of code.

Ive copied and pasted every line of code in one by one in the ruby console but keep getting a syntax error when i put this line in

newdefs.each{|defn|tr=Geom::transformation.new(pt)model.entities.add_instance(defn, tr)pt.x=pt.x+1.m}

All the definitions are have been added, just cant seem to get any instances into the model?
Can you shed any light for me - sorry this keeps coming back to you.
Thanks
Sam

You can't have multi-line blocks in the Ruby Console [expect perhaps on a MAC?].
Making it as one line you need ' ;' where the newline would be... so

newdefs.each{|defn|tr=Geom;;transformation.new(pt)model.entities.add_instance(defn, tr)pt.x=pt.x+1.m}

should become

newdefs.each{|defn|tr=Geom;;transformation.new(pt);model.entities.add_instance(defn, tr);pt.x=pt.x+1.m}

NOTE this is all in one line but the code-pane 'wraps' it...
Then it should work...

Am I missing a step - am working on PC and am pasting each line into ruby console one at a time... but still get this unexpected tIDENTIFIER error? Im afraid I can't troubleshoot this at all with my very limited ruby knowledge. Any ideas?

samyell77

[hr]just spotted that I was missing the ';' in this line just before 'pt.x' but have added it in, re-run and am now getting a different error (have highlighted the code in red this time and the result from the ruby console in blue...)

skpfolderpath='C:\Users\sam.morris\Documents\TEST COMPS';model=Sketchup.active_model;ents=model.active_entities;defs=model.definitions;skps=[;Dir.foreach(skpfolderpath){|f|skps << File.join(skpfolderpath, f) if File.extname(f).downcase==".skp"};skps.each{|skp|defn=defs.load(skp)}]

Also added ';' to all the lines of code to make complete blocks so I could paste a whole block in in one go rather than line by line - hope this is ok...

Dan Rathbun

Another cap error on the same line:

newdefs.each{|defn|tr=Geom;;transformation.new(pt);model.entities.add_instance(defn, tr);pt.x=pt.x+1.m}

should be:

newdefs.each{|defn|tr=Geom;;Transformation.new(pt);model.entities.add_instance(defn, tr);pt.x=pt.x+1.m}

class (and module,) identifiers are actually constants so start with a capital character.

TIG

Thanks Dan, I missed the [tT]ransformation typo in his code I copy/pasted.....
The error messages are pretty good at telling you what is wrong

samyell77

TIG, Dan,
Yee haaa! It works! Thank you both so much - TIG, thanks for being patient with a ruby luddite and Dan, thanks for finding the final missing piece of the puzzle. You have both been a huge help.

Grrr - curses, they load in but something is going wrong Im afraid.

Copied and pasted code below - no error messages appearing but the components aren't all there and some of them are broken up / exploded it seems. I have 4 components that Im loading in this case (PLAT Carpet Amber FULL Diagonal A, B, C & D) but when I run the code I only get C and D as complete components and then I get two groups of objects that are broken up?

Ive attached a screen grab - the bottom row is the components as they appear after running the lines of code. The top row is the components loaded from the components pallet.

Ive also pasted the code from the console below...

skpfolderpath='C:\Users\sam.morris\Documents\TEST COMPS';model=Sketchup.active_model;ents=model.active_entities;defs=model.definitions;skps=[];Dir.foreach(skpfolderpath){|f|skps << File.join(skpfolderpath, f) if File.extname(f).downcase==".skp"};skps.each{|skp|defn=defs.load(skp)}
["C:\Users\sam.morris\Documents\TEST COMPS/PLAT Carpet Amber FULL Diagonal A.skp", "C:\Users\sam.morris\Documents\TEST COMPS/PLAT Carpet Amber FULL Diagonal B.skp", "C:\Users\sam.morris\Documents\TEST COMPS/PLAT Carpet Amber FULL Diagonal C.skp", "C:\Users\sam.morris\Documents\TEST COMPS/PLAT Carpet Amber FULL Diagonal D.skp"]
pt = Geom::Point3d.new(0,0,0)
Point3d(0, 0, 0)
newdefs = defs.to_a[(defs.length - skps.length)..-1]

[#Sketchup::ComponentDefinition:0xe60a9d8, #Sketchup::ComponentDefinition:0xe60a8e8, #Sketchup::ComponentDefinition:0xe60a8ac, #Sketchup::ComponentDefinition:0xe603908]

Any further thoughts or help with this much appreciated.
Thanks

Your imported components contain subcomponents or groups - these have definitions.
The current code simply takes the definitions list, and because definitions are added onto the end it it assumes the last 4 [say] are the 4 components you loaded, but of course there are more than that because the subcomponent/groups are all extra definitions too - so you only get the first few and not all.
We can recode so that we make an array of the definitions before the import and then an array after an find the difference, skipping groups... that way you only get new components added as instances... I've also added a sorting routine to add them in order...

model=Sketchup.active_model;
defs=model.definitions;
olddefs=defs.to_a;
skpfolderpath='C;\Users\sam.morris\Documents\TEST COMPS';model=Sketchup.active_model;ents=model.active_entities;
skps=[];
Dir.foreach(skpfolderpath){|f|skps << File.join(skpfolderpath, f) if File.extname(f).downcase==".skp"};
skps.each{|skp|defn=defs.load(skp)};
newdefs = defs.to_a - olddefs;
newdefsnames=[];
newdefs.each{|defn|next if defn.group? or defn.image?; newdefsnames << defn.name};
newdefsnames.sort!;
pt = Geom;;Point3d.new(0,0,0);
newdefsnames.each{|name|tr=Geom;;Transformation.new(pt); model.entities.add_instance(defs[name], tr); pt.x=pt.x+1.m};

Hope this helps [untested...]

As we say in the west country "Thats the badger mi babber!!"

Works a treat now TIG - brilliant!

Thanks again for ALL your help with this and you patience
