Moving groups.

[surf808]

Hi. I had a question hopefully you could help me with. I have two
programs one which makes the objects and another which calls on it. I
want the program that calls on it to move the objects around. Here is
the code I'm working on.
z = 0
while (z < zdd)
y = 0
while (y < ydd)
x = 0
while (x < xdd)
group2 = group.copy
group2.transformation = [x, y, z]
x = x + stepx
end
y = y + stepy
end
z = z + stepz
end
group.erase!

I can move just one of the blocks but I want to move them all
together. So in short I'm wondering how to make them all into the same
group so I can pass it to the other program and move them around.

Thanks.

You don't have to put them all in the same group to move them all.
You can apply a transformation to all of them at once with
transform_entities()

I am still having trouble. What I want to do is draw the entire wall
in one position. Then when that is complete move it to some other
point. When I do the method you suggested the only block that moves
is the last one. I tried something like this

point = Geom::Point3d.new(-400,-400,-400)
t = Geom::Transformation.new point
status = entities.transform_entities t, group2

The point with transform_entities() I was trying to make, but failed
to do so, was that you can supply several objects at once, like this:

status = entities.transform_entities t, group2 , group1, group3,
group233, group1056, etc.

Oh I see. Isn't there a way to transform them all at once? Is there
a way of selecting all objects on a certain layer and transforming
them?

I got it to work. What I did was make a new group. I called it
group3[count] = group2. So I copy each in the while loop. Then I
have another to move them all again counting through each count in the
group3. If you have a better suggestion let me know.

group3 = []
count = 1

z = 0
while (z < zdd)
y = 0
while (y < ydd)
x = 0
while (x < xdd)
group2 = group.copy

point = Geom::Point3d.new(x, y, z)

t = Geom::Transformation.new point

entities.transform_entities t, group2
group3[count] = group2
count = count + 1

x = x + stepx
end
y = y + stepy
end
z = z + stepz
end
group.erase!

UI.messagebox count
point = Geom::Point3d.new(pointx,pointy,pointz)

t = Geom::Transformation.new point

count = 1
while (count <= 126)
group3[count].transform! t
count = count+1
end

You don't need to create yet another group if you don't want to - just
pass all the groups you want to move to transform_entities in a single
call. Done - finished - simple.

transform_entities() accepts a varying list or arguments - it doesn't
care how many you pass.

To move everything in the model up two units, you could create your
[0,0,2] transformation as "t", then call the method like this:

Sketchup.active_model.entities.transform_entities( t ,
Sketchup.active_model.entities )

I tried your suggested method and get the error that
transform_entities. It says wrong argument type (expected
Sketchup::Entity).

Yes, I wasn't 100% precise, and no, you didn't think for yourself to
figure it out.

If the following is entered from the Ruby console, it will shift
everything to the right 50 units (when viewed from the default plan
view):

ent = Sketchup.active_model.entities
t = Geom::Transformation.new( [ 50 , 0, 0 ] )
ent.transform_entities( t , ent.to_a )
