Explode and regroup script?

Why? Is there a point to this exercise?
Hi! The reason is that I can't use "drop to terrain" plugins like DropGC and Raytracer. I select the groups and click the plugin but nothing happens.
BUT if I explode and regroup them (one by one), everything works normally. I really dont know why...I'm with you, I can't figure out why this is so. But, since these are buildings, you wouldn't want them to conform to the surface like Pilou's SmartDrop demo. So something as simple as
mod = Sketchup.active_model sel = mod.selection sel.grep(Sketchup;;Group){|g| t=mod.raytest([g.bounds.min,[0,0,-1]])[0] g.transform!(Geom;;Transformation.new(t-g.bounds.min)) if t }This works on your groups whether they are exploded and regrouped or not.
Select group(s), paste code into Ruby Console, press Enter.

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

Hi, Sdmitch!
Thaaaank you so muchh!! That's all what I needed!!

How do you create that ?Hi, Pilou!
First of all, thank you so much for all support you are giving to me.
Yes, the groups states remain. Mystery!
I've used Autocad Map 3d to generate those buildings with their proper heights attaching a shapefile. Before I export, I converted polygons to solids using -convtosolid command.
Then I saved as .dwg to export those buildings to Sketchup. -
Even genious Sdmitch has find a solution for your problem
taka a look to these architect tools by Thomthom!A suite of tools to help with imported DWG files aimed at Architecture
Maybe there there are some tricky things nside! -

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

(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". -

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.

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])}

It is working perfectly!!

Always amazazed that few line can make! Bravo!

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? -

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!!!
