Move groups with different measures?

[thomthom]

SU always uses inches internally.

If you want 100mm type 100.mm . See http://code.google.com/intl/nb/apis/ske ... meric.html for more units.

[TIG]

Pilou

Do you want to move each of the selected groups by the same amount (my code - e.g. 100.mm) or by an ever changing amount ?

If you want it to change then you need to define how, and add this into the loop - e.g. z=1..... then loop... z += 2*z
exponential type increase !

If you are applying different offsets, and you have made the groups in order, then the increments will apply in that way; but it would be possible to 'stack' groups made at different times and the loop would process then in their made order, but not the 'stacked' order you want ! Perhaps you need to add in another test... for each of the group.bounds.min.z. which sorts them by their relative heights, so at least the groups array would be in the height order you expect...

[Pilou]

If you want 100mm type 100.mm

Yes! Works like a charm!
For my first one that was not like a true romance but with your help, ThomThom, Tig (yet a lot of cryptic for me , and the Chris tutorial and a dash of milk of Tod Burch
Many thx for the helps

Next will maybe an "explode view" of several groups
Just need to know position of a group

PS @ Tig Sorry but I had no chance with yours! (see previous page)
And yes I want any sort of increments so now I can have any sort of it! Thx!
Just play with parameters
I keep your group.bounds.min.z. trick in my mind!

[TIG]

for a completely random offset try

Code: Select all

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

[Pilou]

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?

[thomthom]

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.

[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

[Chris Fullmer]

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

[TIG]

Try something like...

Code: Select all

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)

Code: Select all

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...

Code: Select all

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

[Pilou]

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

[Pilou]

another try found: undefined method ‘[]’

Code: Select all

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?

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
