Explode and regroup script?

But that resolve not the little mystery of the 2 groups states!
What are special on them ?
How do you create that ?

My new project for the weekend!!!!!!!!

I believe that the problem comes from the export DXF from external program!
(double vertices ?...)

No the problem is that the transformation.origin is not over the "surface"
` name = Group#445
origin = (-420.075838m, -663.573913m, 8.06m)
x axis = [1.0,0.0,0.0]
y axis = [0.0,1.0,0.0]
z axis = [0.0,0.0,1.0]
x,y,z = [-16538.41882347539,-26124.9572089176,317.32283464566945]

name = Group#468
origin = (-420.075838m, -663.573913m, 8.06m)
x axis = [1.0,0.0,0.0]
y axis = [0.0,1.0,0.0]
z axis = [0.0,0.0,1.0]
x,y,z = [-16538.41882347539,-26124.9572089176,317.32283464566945]` which is why the "Drop" fails. By exploding and regrouping the group, the transformation.orig is reset to bounds.min which is over the "surface".

-So that means I need to explode and regroup to reset them? Or there is another way to change their transformation.orig to bounds? Sorry, I didnt understand very well..
-I'm using your script to drop the groups down to terrain, but I'm having some problem... Many groups arent dropping well, they fly.

Could you post a sample of the one's that "fly".

The problem is some groups being dropped on "top" of others already moved to the surface.

So to avoid that conflict, I have modified the previous code I posted.

mod = Sketchup.active_model
sel = mod.selection
gat = []
sel.grep(Sketchup;;Group){|g|
 o = [g.bounds.center.x,g.bounds.center.y,g.bounds.min.z]
 p = mod.raytest([o,[0,0,-1]])[0];
 gat<<[g,Geom;;Transformation.new(p-g.bounds.min)] if p
}
gat.each{|g| g[0].transform!(g[1])}

Oh my God, thank you so much, sdmitch!!
It is working perfectly!!

I'm sorry, Sdmitch... There is still one problem..

The groups are moving by Z axis perfectly, but when it goes down to terrain, they are changing their X and Y positions. They are messing with each other..
Why is it happening?

Oops. My bad. I forgot to change the "origin" in the transformation. Code has been fixed.

Wonderful, Sdmitch!
Now it is perfect!!!
Thank you so much!!!
