Is that the only error message you get?

it's like a snowball on the top of the mountain

You're hooked now! No way back!

[TIG]

Here's some tweaked code

Code: Select all

def test()
    model = Sketchup.active_model
  model.start_operation("Move in Z")
    entities = model.entities
    selection = model.selection

    zeds=[]
    index=0
    sorted_groups=[]

    groups=[];selection.each{|entity|groups.push(entity) if entity.kind_of?(Sketchup::Group)}

    groups.each{|group|zeds.push([group.bounds.min.z, index])
       index+=1
    }
    zeds.sort!
    zeds.each{|z|sorted_groups.push(groups[z[1]]) }
    ### sorted_groups is now groups sorted by

    z = 0.0
    sorted_groups.each do |e| # update!
      # Now we process the groups
      t = Geom::Transformation.new(Geom::Point3d.new(0,0,z))
      # Apply the transformation
      e.transform!(t)
      z = z + 100.cm
    end
   
  model.commit_operation
  return nil
 
end#def


Runs as 'test'.
I made a typo - it needed an array [] of two items adding to zeds: zeds.push([group.bounds.min.z, index]) not two 'loose' items as in zeds.push(group.bounds.min.z, index).
I made your z = 0 into z = 0.0 as it needs the number as a float, not an integer...
Removed 'point' variable and set the point definition directly inside the transformation - not necessary but fewer variables...
I added a model.start_operation("")...model.commit_operation so it becomes a one step undo.
I added return nil at end so the Ruby-Console doesn't get clogged with info...

Tested it - it works...

[Pilou]

Seems indeed that some corrections were necessary
This time works like a charm! Excellent! TIG + Thomthom! Bravo!
I will see all that more in detail for learn this little cryptic language !
Very funny plug!
For the next Pilou's foolish...
...I need to know the "centroïd" (xyz) of a "bounding box's group"
Here of course without different measure, just for little test! (click image)

[TIG]

...I need to know the "centroïd" (xyz) of a "bounding box's group"

Code: Select all

centre_point=group.bounds.center

See http://code.google.com/apis/sketchup/docs/ for all these details

[Pilou]

Thx I had missed this one

[Pilou]

I have replaced "Group" by "Component" but seems that is not so simple

Code: Select all

groups=[];selection.each{|entity|groups.push(entity) if entity.kind_of?(Sketchup::Component)}

    groups.each{|component|zeds.push([component.bounds.min.z, index])

Else I can yet nest a component inside a group color transparent
That works fine (just disable Edges visible) but I suppose there is another thing

[thomthom]

It'd help if you posted the error messages.

However, I can still see the problem here. Sketchup::Component isn't an SU object. Check the manual, you have Sketchup::ComponentDefinition and Sketchup::ComponentInstance. In your case you're looking for a Sketchup::ComponentInstance.

[Pilou]

Yep!!! THX! Miracle that is working!
Sure I should read the Api document before But I had risked the trick
So my second script was a new speedy success and a big lesson

groups=[];selection.each{|entity|groups.push(entity) if entity.kind_of?(Sketchup::ComponentInstance)}

groups.each{|ComponentInstance|zeds.push([ComponentInstance.bounds.min.z, index])

Copy my code follow in the Web console from Jim Foltz
(if you have components use the file linked )

Code: Select all

    model = Sketchup.active_model
    model.start_operation("Move in Z")
    entities = model.entities
    selection = model.selection

    zeds=[]
    index=0
    sorted_groups=[]

    groups=[];selection.each{|entity|groups.push(entity) if entity.kind_of?(Sketchup::Group)}

    groups.each{|group|zeds.push([group.bounds.min.z, index])
       index+=1
    }
    zeds.sort!
    zeds.each{|z|sorted_groups.push(groups[z[1]]) }
    ### sorted_groups is now groups sorted by z

    z = 0.0
    sorted_groups.each do |e| # update!
      # Now we process the groups
      t = Geom::Transformation.new(Geom::Point3d.new(0,0,z))
      # Apply the transformation
      e.transform!(t)
      z = z + 100.cm
    end
   
  model.commit_operation
  return nil


Some help for fun variations

[Pilou]

Come back in these very dangerous territories

As I understand that retrieve the center XYZ of the bounding box group by

Code: Select all

 center = boundbox.center

but how give these 3 values(?) to these 3 variables ?
xc= ?
yc= ?
zc= ?
must be trivial but yet some foggy for me
PS I read the API from the end to the start, and inverse but this stay mysterious found anything except that

[thomthom]

boundbox.center returns an object of type Point3d. You can check what an object is by checking the .class value of an object. That gives you an indication to where to look.

Code: Select all

xc= boundbox.center.x
yc= boundbox.center.y
zc= boundbox.center.z


[Pilou]

Many thx!
It's always the more easy ans usefull who is not written as example

[Pilou]

??? = error : in ‘initialize’: undefined local variable or method ‘boundbox’

Code: Select all

model = Sketchup.active_model
entities = model.entities
selection = model.selection
#groups = []
xp=100  # Pivot Point
yp=100
zp=100

xc=0  #Center Point of the grouped object
yc=0
zc=0

xe=0  #End Point of the grouped object
ye=0
ye=0

selection.each do |e| # update!
  # Skip all entities that aren't groups
  next unless e.is_a? Sketchup::Group
  # Now we process the groups

 center = boundbox.center
        xc= boundbox.center.x # ??? error
   yc= boundbox.center.y
   zc= boundbox.center.z
   
xe=xc
ye=yc
ze=zc
if xc<xp
xe =xc - 100
end
  if xc>xp
xe =xc +100
end

if yc<yp
ye =yc - 100
end
  if yc>yp
ye =yc +100
end

if zc<zp
ze =zc - 100
end
  if zc>zp
ze =zc +100
end

  point = Geom::Point3d.new xe,ye,ze
  t = Geom::Transformation.new point
  # Apply the transformation
  e.transform!(t)
end

[thomthom]

That's because of center = boundbox.center <- you haven't referenced boundbox yet.

Code: Select all

center = boundbox.center
        xc= boundbox.center.x # ??? error
   yc= boundbox.center.y
   zc= boundbox.center.z


change to

Code: Select all

center = e.bounds.center
   xc= center.x
   yc= center.y
   zc= center.z


[Pilou]

Thx!
More easy with that Works like a charm
I can now test some natures of explodes

[Pilou]

Funny thing

[Pilou]

Some tests Put the code inside the WebConsole by Jim Foltz
Press "Eval" button and have fun
Veyron model is from 3Dwarehouse!

Code: Select all

model = Sketchup.active_model
entities = model.entities
selection = model.selection

xp=100  # Pivot Point (as you want)
yp=100
zp=100

q=50 # Measure of translation (as you want)

selection.each do |e| # update!
  # Skip all entities that aren't groups or components (replace follow "ComponentInstance" by "Group" if you have groups
  next unless e.is_a? Sketchup::ComponentInstance  # Now we process the component or group
 center = e.bounds.center #Center Point of the grouped object
   xc= center.x
   yc= center.y
   zc= center.z
   
xe=xc #End Point of the grouped object
ye=yc
ze=zc

if xc<xp
 xe =xc - q
end

if xc>xp
 xe =xc + q
end

if yc<yp
 ye =yc - q
end

if yc>yp
 ye =yc + q
end

if zc<zp
 ze =zc - q
end

if zc>zp
 ze =zc + q
end

  point = Geom::Point3d.new xe,ye,ze
  t = Geom::Transformation.new point
  # Apply the transformation
  e.transform!(t)
end

Looking good Pilou!
Instant assembly drawings! This should come in handy.

[Pilou]

Instant assembly

Alas for the inverse, that must be more tricky!
Better is use the Undo

[thomthom]

hm... You could store the relative position you move the entities by in and attribute dictionary. Then perform the opposite when you want to reassemble.

though, that will fail if the user moves anything...
Maybe, you could store the original absolute position before you move stuff. Then you can reassemble back to that original position. That would allow the user to move things around as they please.

[Pilou]

In theory that must be more easy
Just select that you want and apply a "negative" translation : a deflation
Maybe my next
And the above is not yet perfect! The Pivot Point seems not have the wished result wanted
be continued...

Ps When Groups or Components are nested how to process automatically?
A plug for make each components individual is maybe existing?
Edit
one exist for group by TIG Explode2groups

miss now somethings transform Transform2goups or Explode2Components

[Chris Fullmer]

Store the original transformation in a dictionary attached to the group/component. Then to unexplode, just re-apply that transformation onto the group. It will go right back where it belongs.

I wrote that crazy scrambler script a while ago that does this and it worked very well.

[Pilou]

@Chris Any chance to see it somewhere?

[Chris Fullmer]

take the componentInstance, add it to a group, then explode the component instance.

And I posted my scrambler script here. I'll see if I can find the thread.

[Pilou]

@Chris thx for the Info
Fredo6 has inside the FredoScale something who transform any selection of groups or Components in "Unique" groups or componants! (each become individual)
