[REQ] Open and close all nested groups in selection

[Pixero]

Would this work?

selection=Sketchup.active_model.selection 
selection.grep(Sketchup;;Group) {|group| group.make_unique }

[TIG]

After the selection grep you need a .each ...
Sketchup.active_model.selection.grep(Sketchup::Group)**.each**{|g| g.make_unique }
or to do it to ALL groups do this ...
Sketchup.active_model.definitions.select{|d| d.group? }.each{|g| g.make_unique }

[Pixero]

Thanks.

I use the backout plugin to exit nested groups...

[Pixero]

Hmm...I tried it exactly as you wrote but it didn't work.

But, if I manually double click to open the groups and then close them and run the hide intersecting edges script it works.

Any ideas what could be missing?
I don't get any error messages in the console.

If you use this line in the Ruby Console what is listed ?
gps = Sketchup.active_model.selection.grep(Sketchup::Group)
If it's a list of selected groups, then what happens with this ?
gps.each{|g| g.make_unique if g.entities.parent.instances[1] }
There's no need to use 'make_unique' unless there are multiple copies ??

[Pixero]

That seem to work.
Again, thanks!

[Pixero]

I spoke to soon. It doesn't work if there are nested groups.

I knew I had seen a similar discussion some where. This might be what you are looking for.

I think there is a newer version in the plugin store.

Never mind, as written, the plugin fails with nested groups.

I think it would be an easy fix.

.grep takes a block which it will invoke on all matched elements. On large sets it's somewhat faster.

Can someone make a script that open and close all nested groups in a selection?

The code below makes a recursive traversal through nested groups. I will add an UI to the hide overlapping extension where make_unique is an option.

  
  def self.makeUnique(ents)
    ents.grep(Sketchup;;Group).each { |g|
      g.make_unique
      makeUnique(g.entities)
    }
  end

  makeUnique(Sketchup.active_model.selection)

I tried your code but it didn't work with nested groups either.

I think there are two issues here.

1. HideOverlappingGeometry does not compare groups within a common top group. So in your example, the 4 boxes within a group will not be compared with each other, they will however be compared to the 4 boxes in the other group. That's just a choice I made in the extension that reflects the way I use the script. If you want to hide the seams between the groups within a group you have to enter the group and select all groups within and then run the script. I think I will add an option to the extension so that is also compares stuff within the same nesting.

2. I don't quite see why the provided code doesn't work in your example. I tried with a similar example and the groups all became unique. Do you have a sample model?

[Pixero]

Here is a simple example file.
A real life model would probably have more nested levels.

I get the result below (and the nested groups also becomes unique):

Ok, so then it's a matter of you implementing the compare overlapping edges in nested groups?
