[REQ] workflow tool -make groups of components (nested)

[TIG]

You haven't explained yourself very clearly.

If I understand you correctly your CAD programs exports directly into SKP.
It uses SUp components [which were presumably CAD-blocks] rather than SUp groups.
I assume it also includes 'loose-geometry' too...

This is to be expected...
If you were to Import the CAD [DWG/DXF] file into a SKP the very same thing will happen.
However, in that case all of the imported objects should be inside a single new component named after the imported file and therefore that'd perhaps be more readily editable.
Using the Outliner you can select whatever component[s] you want and use Explode [Edit/context-menu or recommended, use a Shortcut-key], exploded objects' geometry remains highlighted so you can immediately make that into a new group, again using Edit/context-menu or recommended, use a Shortcut-key - Entity Info can be used to rename the group after the component.

To tidy up the Components Browser you can purge unused from either its pop-out menu OR from Model Info > Statistics - which also removes unused materials, layers etc that might otherwise get left behind after the components are removed from the SKP...

This one-liner can be copy+pasted into the Ruby Console and it will convert all selected [other things are simply ignored so you don't need to be too careful!] component-instances into groups, using the the same names/layer/materials etc...

m=Sketchup.active_model;as=m.active_entities;m.start_operation('Co>>Gp');m.selection.to_a.each{|e|next unless e.is_a?(Sketchup;;ComponentInstance);n=e.definition.name;o=e.name;l=e.layer;t=e.material;x=e.explode;es=[];x.each{|f|es<<f if f.is_a?Sketchup;;Drawingelement};g=as.add_group(es);g.name=n+"#"+o;g.layer=l;g.material=t};m.commit_operation;

It is one step undo-able...
It doesn't deal with nested instances BUT repeated a few times on a selection it will 'group-ify' them all...

I replied in your parallel posting... I have merged them into this one... to avoid confusion...

hi there again.

where would i find help or a compendium that helps me selfteach how 2 generate a working script?!

i thind your could be a great base for what i want!
Find the free PDF on the www called Automatic-SketchUp...
Also get simple a few scripts [there are hundreds!] and read them in Notepad/Notepad++ to see/learn what they do.
Also the learn the API = https://developers.google.com/sketchup/docs/
There are also several excellent resources in the Developers' section of SCF...
Learn to use the Search tools...
