Hi, I'm trying to find the position of a group in the active context, relative to the coordinate system of the group that it contains (which itself can be contained within other groups), this picture illustrates the situation

You may also need to do this but with components. Really, I do not find the way to accomplish what I need, I appreciate your help

.

wow thanks Dan, I will take some time to study this code, worth but me several questions arise, I will try to solve the most I can on my own, thank you very much
(google translator)

I did this and I get "error", I couldn't see what is wrong

mod = Sketchup.active_model
definitions = mod.definitions.to_a

def find_entity(dname)
  found = nil
  for d in definitions
     next if d.image? 
     found = d.instances.find{|i|
       i.attribute_dictionary(dname)
     }
     break if found
  end # for
  return found
end # def

entity = find_entity("dic1")

Thanks Dan, I find it very nice your suggestion, I will give a chance to this

Thanks for replying TIG, I really needed to know the two things, I was lost without your help

(google translator)

TIG thank you very much, I will try that

I was trying something, but is a bit more complicated:

idd = "dic1"
hit = nil
mod.definitions.each{|d|
   next if d.image?  
   d.instances.each{|i|
      next if i.attribute_dictionaries.to_a.size<1
      dictio = i.attribute_dictionaries.to_a
      if dictio[0].name==idd
         hit=i           
         break
      end
   break if hit
   }
}

I'm reading carefully the lines of code and I'm learning TIG proposes several things, another question arises me, suppose that I assign a different name to each dictionary of each entity and I want to find the entity using the name of the dictionary. How can I modify the condition
" if i.get_attribute("dacastor 666", "id", nil)==idd "?
(google translator)

wow! thank you very much TIG is exactly what I needed, just some things I do not understand, that is .image?, break and break if hit

and one more question, is there anything I can use instead of .make_unique? is that the documentation say it is an outdated method

Hello, I want to make a code that gives a name or a mark to groups (or components) that are selected, so that I can then refer to this object from code without being selected at that time and then apply for example a transformation
t = Geom::Transformation.scaling 10 entity.transform!

for now the only thing I've accomplished is to name the group, but I do not believe this will serve for my purpose

modelo = Sketchup.active_model

if Sketchup.active_model.selection.empty?
   UI.messagebox "seleccione un grupo o un componente"
   return
end

i=0
entidades=[]
modelo.selection.each { |entity| 
 if entity.is_a?(Sketchup;;Group)||
    entity.is_a?(Sketchup;;ComponentInstance)
    i=i+1
    entidades[i-1]=entity 
    entidades[i-1].make_unique
    entidades[i-1].name = "Entidad #{i-1}"
 end
 }

I thought about using entityID but do not quite understand how you could use this, besides not persistent between sessions.

Nice!
I read that if the glass is pyrex and the liquid is like canola oil (Could be another oil),
there is no refraction.

this is correct if oil index and the index of the glass are the same
however both indices of refraction index will be different compared to air, so there will be refraction when light passes from glass to air or air to glass

Today and tomorrow are the last days to vote for the video that I did, thanks for your help (google translator)

Refraction is such an interesting behavior!

Voted for this entry in hopes you get some recognition for this awesome video. The music complemented the animation very well and made it beautiful.

Exito!

thank you very much for your words, encourages me to continue making videos!!

@jo-ke said:

I have facebook but I'm not able to see the video.

just follow the instructions 1), 2) and 3) I put up, I appreciate your interest

Voting closes on November 15, thank you for your support

very nice!

I share a project of mine:
http://sketchucation.com/forums/viewtopic.php?f=81&t=48792

Hi, this is a video I made ​​for a contest, the objects were made ​​in sketchup and rendered with vray %(#a3a3a3)[(must have facebook to see the video):

http://bit.ly/QsAQ6i

If you like, you can vote for this video
Here are the steps to help:

1. give "like" to "The Optical Society"
2. give it to accept Offerpop
3. give the button that says "VOTE" coming out next to the video]

leave a picture of project:

I spend around 8 hours of work to this project, render 26 hours.
(I used google traslator)

That limit the size of your render to the size of the viewport. If you need highres images, but in the same aspect ratio of the viewport use the "Get view aspect" button and then lock the aspect ratio. Then you can increase the output size and still be relative to SU. So if you save out a 3000px wide image in SU and then render out a 3000px wide image in VfSU they match, no problem.

ok, I like your solution

Hi all, I want to share a trick I discovered yesterday to match the output of V-Ray and output SketchUp. It's easy all you do is turn off the "Override Viewport" in the section "Output"

[xxl-img:xt62k5vq]https://sites.google.com/site/dacastror/archivos/vray ouput.png[/xxl-img:xt62k5vq]

By doing this no matter how you change the size of the SketchUp window or change the value of "Field of View" in Sketchup

I put these images as an example:

Vray output:
[xxl-img:xt62k5vq]https://sites.google.com/site/dacastror/archivos/cristal D.jpg[/xxl-img:xt62k5vq]

SketchUp output:
[xxl-img:xt62k5vq]https://sites.google.com/site/dacastror/archivos/paracristal.png[/xxl-img:xt62k5vq]

Combination using photoshop:

I guess some of you already knew but maybe others do not, I hope will be helpful

(sorry for errors of the machine translator)

hi all, wanted to present my first render spherical done with Sketchup + Vray and hosted on 360cites

http://www.360cities.net/image/holographic-optical-assembly?override_cache=true#145.26,28.52,58.3

it is a replica of the digital holographic optical lab at my university in Colombia, I hope you like

Check out the source of this plugin that draws edges of the boundingbox: http://forums.sketchucation.com/viewtopic.php?t=29377#p256536

Thom thank you very much.
I know I need this in lines 66 to 68 of your code:

definition = self.get_definition(entity) bb = definition.bounds pts = self.bound_points(bb).map { |pt| pt.transform( entity.transformation )

is a shame that is not yet ready to understand these lines clearly, however I will be very useful, very grateful

(sorry for my bad English)

I know you helped me very much, sorry for asking much just I want to learn
