Access specifies entity

[ymagrini]

Hi, again.
I need your help.

I perform an automatic ruby code for change colors of group, but I can't select the specified entity.

My code start from this:
Sketchup.active_model.active_entities.grep(Sketchup::Group).each do |group|
[:........]

the poblem is that when open the sketchup project, active_entities is:

Sketchup.active_model.active_entities
#Sketchup::Entities:0x00000008fbfd08

in this mode, groups thus are not found.

but, when perform double-click into specified group, then acitve_entities is:
Sketchup.active_model.active_entities
#Sketchup::Entities:0x0000000b5deef8

(note that is another id)

how can't find another entity or set active_entity ??

if do a loop or i access by index, then get another components......

Sketchup.active_model.entities[0]
#Sketchup::ComponentInstance:0x00000008fbfc90

Sketchup.active_model.entities[10]
#Sketchup::Edge:0x00000008fbf948

.....

Thanks, very much

Yamil.

It only matters what context you need to be in. The .active_entities will include the entire model if no group or component is open for edit otherwise just the contents of the open group or component will be in the .active_entities.

Sketchup.active_model.active_entities.grep(Sketchup;;Group).each do |group|
 group.material=[rand(256),rand(256),rand(256)]
end

# Search top and 1st nested level for a named group;

grps = Sketchup.active_model.active_entities.grep(Sketchup;;Group)

if !grps.empty?
  found = grps.find {|grp| grp.name = "Target Name" }
else
  found = nil
end

if !found # found will be nil, if group was not found

  nested = Sketchup.active_model.entities.find_all {|ent|
    ent.is_a?(Sketchup;;Group) || ent.is_a?(Sketchup;;ComponentInstance)
  }
  
  nested.each {|ent|
    ents = ent.is_a?(Sketchup;;Group) ? ent.entities ; ent.definition.entities
    grps = ents.grep(Sketchup;;Group)
    found = grps.find {|grp| grp.name = "Target Name" } if !grps.empty?
  }
  
end

# found will be the group reference, if it was found
# found will be nil, if group was not found
