Move groups with different measures?

TIG

for a completely random offset try


selection.each do |e|
    next unless e.is_a? Sketchup;;Group
    ###point = Geom;;Point3d.new 0,0,(1000.mm * rand)
    ### offset in Z somewhere between 0m and 1m - 'rand' makes a random number 0><1
    point = Geom;;Point3d.new (1000.mm * rand),(1000.mm * rand),(1000.mm * rand)
    ### offset in all XYZ axes by 0 to 1m
    t = Geom;;Transformation.new point
    e.transform!(t)
end

Swap the ### between the different points = to see the effect

The entities are not returned in their order in z height. You would need to sort the objects by their Z position before applying the transformations.

Before testing your new randomizer plug

I have a little problem
I have used "Grow" by Tig for make the "volume" on the left (50 groups), then my "Plug" Thomthomised
with a normal interval of course!
Seems there is something wrong somewhere
Groups are not recorded following the "grow" generation?

pilou

So i must use the Tig Advertissement more soon than I have expected

pilou

This group.bounds.min.z. can be found somewhere or the sorting of Groups must be forged again?
(nothing about sort, sorting in the API helping)

thomthom

Build a hash with the entities as the key and their Z posiiton as value and then sort the hash by the values.

pilou

Each groups has not a "time creation" trace board? So no need to remake a sorting ?
Seems I have re-open a new nightmare door

Awesome Pilou! Keep it up, its looking great. You've got lots of good help around here.

Try something like...


zeds=[]
index=0
groups.each{|group|
   zeds.push(group.bounds.min.z, index)
   index+=1
}
zeds.sort!
sorted_groups=[]
zeds.each{|z|sorted_groups.push(groups[z[1]]) }
### sorted_groups is now groups sorted by Z

pilou

Does the group.bounds.min.z only valuable in SU 7?
Edit seems not

little try but seems I miss something (any doubt selection but the sorted_groups gives nothing on the screen)

model = Sketchup.active_model
entities = model.entities
selection = model.selection
groups = []
z=0
zeds=[]
index=0
groups.each{|group|
   zeds.push(group.bounds.min.z, index)
   index+=1
}
zeds.sort!
sorted_groups=[]
zeds.each{|z|sorted_groups.push(groups[z[1]]) }
### sorted_groups is now groups sorted by Z

sorted_groups.each do |e| 
  point = Geom;;Point3d.new 0,0,z
  t = Geom;;Transformation.new point
  e.transform!(t)  
  z =  z + 1000.mm
end

TIG

groups = [] then nothing set !!!
You emptied the groups array...
You need to fill it from the selection...

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

pilou

another try found: undefined method ‘[]’

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

z=0
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 

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

thomthom

Is that the only error message you get?

You're hooked now! No way back!

Here's some tweaked code

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)

centre_point=group.bounds.center

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

pilou

Thx I had missed this one

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

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

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
