Can anyone help me with move vertices

mod = Sketchup.active_model 
ent = mod.entities 
sel = mod.selection 
mass = []
arr = []
sel[0].make_unique
sel[0].entities.each { |entity| arr << entity.make_unique}
for i in 0..arr.length-1
  t = arr[i].transformation 
  arr[i].entities.to_a.each{|line|
    if line.class == Sketchup::Edge
      if ((line.start.position.transform! t).z > 380.mm)
        mass <<  line.start
      end
    end 
    if line.class == Sketchup::Edge
      if (line.end.position.transform! t).z > 380.mm
        mass <<  line.end
      end
    end
  }
  pt = Geom::Transformation.new([0, 0, 100.mm])
  arr[i].entities.transform_entities(pt,mass)
  mass = []
end

Hi, If you change the local axis of the top middle section so the Z axis points UP instead of Right, then you might achieve moving the vertices Up instead of Right.

Suggestion. Instead of this ā€¦

ā€¦ try this ā€¦

inst = sel[0].make_unique
ents = inst.definition.entities.map { |entity| entity.make_unique }
for child in ents
  # code using child ...

This way you avoid any ā€œoff by one errorsā€ and since your not really using the index for any calculations you might as well just use a reference to the child instance rather than repeatedly calling arr[i].

You are right, but the local axis is not fixed.

I tried and the result was the same. Is there any way to change the axes?

mod = Sketchup.active_model 
ent = mod.entities 
sel = mod.selection 
mass = []
inst = sel[0].make_unique
ents = inst.definition.entities.map { |entity| entity.make_unique }
for child in ents
  t = child.transformation
  if child.transformation.zaxis != (0,0,1)
    #Is there any way to change the axes?
    child.axes.set([0,0,0], xaxis, yaxis, Z_AXIS) #
  end
  
  child.entities.to_a.each{|line|
    if line.class == Sketchup::Edge
      if (line.start.position.transform! t).z > 380.mm
        mass <<  line.start
      end
    end 
    if line.class == Sketchup::Edge
      if (line.end.position.transform! t).z > 380.mm
        mass <<  line.end
      end
    end
  }
  pt = Geom::Transformation.new([0, 0, 100.mm])
  child.entities.transform_entities(pt,mass)
  mass = []
end

I do not have your model, so I just guessingā€¦

mod = Sketchup.active_model 
ent = mod.entities 
sel = mod.selection 
mass = []
inst = sel[0].make_unique
ents = inst.definition.entities.map { |entity| entity.make_unique }
for child in ents
  t = child.transformation
  if t.zaxis != [0,0,1]
    pt = Geom::Transformation.new([-100.mm, 0, 0])
  else
    pt = Geom::Transformation.new([0, 0, 100.mm])
  end
  
  child.entities.to_a.each{|line|
    if line.class == Sketchup::Edge
      if (line.start.position.transform! t).z > 380.mm
        mass <<  line.start
      end
    end 
    if line.class == Sketchup::Edge
      if (line.end.position.transform! t).z > 380.mm
        mass <<  line.end
      end
    end
  }
  
  child.entities.transform_entities(pt, mass)
  mass = []
end

Yes. You need apply certain transformation the group/component in a question to align its axes, then apply the inverse of that certain transformation to the entities of group/component.

Note that child.entities will only be successful if the child is a group object.
Component Instances do not have a #entities convenience method.

Safer to use child.definition.entities for both cases.

nice, that worked.

How to do it, I want to know.thanks!
