Move groups with different measures?

Chris Fullmer

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

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

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...

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

pilou

@ Tig Some cryptic but I will see that
Joint an image for no ambiguities
So here the increment is 300 cm
Edit sorry I have not seen all these speedy results!

@Thomthom! Yes that is that ! e.transform!(t)

pilou

Come back in these very dangerous territories

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

 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.


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’

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.


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

change to


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
