Hi,

I would like to reproduce the text tool with the Ruby API

I am able to select a face, to get its center, to generate a text with an arrow pointing this center point but when I move the text the point moves too. I would like the point to stay connected to the center of my face (like using the native sketchup text tool)
I do not want to group the text and the face, I would like the same behaviour than the original tool

Any idea?

model=Sketchup.active_model
ents=model.active_entities
sel=model.selection
vec=[10,10,10]
sel.each{|el|    
  if el.is_a? Sketchup;;Face
    bbox = el.bounds
    point = bbox.center
    tt = "Her I am"
    txt=ents.add_text(tt,point,vec)    
	end
}

Thank you TIG for your help

I wrote this function

def getLength pt1,pt2,myGroup
  myLength =  (pt1.transform(myGroup.transformation).vector_to(pt2.transform(myGroup.transformation))).length
  return myLength 
end

#    # for the boundingbox of the group myGroup
#    width = getLongueur bbox.corner(0),bbox.corner(1),myGroup
#    depth = getLongueur bbox.corner(0),bbox.corner(2),monGroup
#    height = getLongueur bbox.corner(0),bbox.corner(4),monGroup

#    # for a edge myEdge of the group myGroup
#    length = getLongueur myEdge.start.position,myEdge.end.position,myGroup

OK it seems great and for a bounding box?

Hi there,

I have a problem with dimensions of a group which has been transformed with the scale tool
(or the edges of a group)

before and after the transformation, I get the same dimensions.

here is my script :

myEdges= []
entGroup = myGroup.entities
entGroup .each do |e|
  if e.is_a? Sketchup;;Edge
    myEdges<< e.length
  end
end
puts myEdges

Is there a better way to get my dimensions using Ruby?

using boundingbox I have the same problem

bbox = myGroup.local_bounds
widthBox = bbox.width
depthBox = bbox.depth
heightBox = bbox.height

Thanks for your help
