Hi, I am new in Ruby. Can someone please explain me how can I extrude a face without any deformation of the initial face. I manage to do this for circle but not for rectangle. Please see:

```
model = Sketchup.active_model # Open model
ents = model.entities # All entities in model
sel = model.selection # Current selection
@edges = []
ents.each do |e|
if e.is_a? Sketchup::Edge
@edges << e
end
end
def gh # -------------------------------------------------------------------------------------------------------- this works
0.upto(@edges.count-1) {|x|
model = Sketchup.active_model # Open model
entities = model.entities # All entities in model
new_comp_def_xy = Sketchup.active_model.definitions.add("extrude")
center = Geom::Point3d.new @edges[x].start.position
vector = Geom::Vector3d.new [@edges[x].end.position.x - @edges[x].start.position.x,@edges[x].end.position.y - @edges[x].start.position.y,@edges[x].end.position.z - @edges[x].start.position.z]
tr = Geom::Transformation.new(center)
circle = new_comp_def_xy.entities.add_circle center, vector, 0.025.m
circle_face = new_comp_def_xy.entities.add_face(circle)
circle_face.followme @edges[x]
tr = Geom::Transformation.new
rest = Sketchup.active_model.active_entities.add_instance(new_comp_def_xy, tr )
}
end
def asd # ------------------------------------------------------------------------------------------------ not working properly
0.upto(@edges.count-1) {|x|
model = Sketchup.active_model # Open model
entities = model.entities # All entities in model
new_comp_def_xy = Sketchup.active_model.definitions.add("extrude")
vector = Geom::Vector3d.new [@edges[x].end.position.x - @edges[x].start.position.x,@edges[x].end.position.y - @edges[x].start.position.y,@edges[x].end.position.z - @edges[x].start.position.z]
gp = entities.add_group()
points = Array.new
points[0] = [0.03.m, 0.03.m, 0.m]
points[1] = [0.03.m, -0.03.m, 0]
points[2] = [-0.03.m, -0.03.m, 0]
points[3] = [-0.03.m, 0.03.m, 0]
points[4] = [0.03.m, 0.03.m, 0.m]
newface1 = new_comp_def_xy.entities.add_face(points)
newface1.reverse!
status = newface1.pushpull @edges[x].length
point = Geom::Point3d.new
as = Geom::Transformation.new(@edges[x].start.position)
Sketchup.active_model.active_entities.add_instance(new_comp_def_xy, as)
points.clear
}
end
```

thank you in advance
