Perfect
I made a stupid mistake
I investigate not
thanks a lot

hello,
As I m a bigginer, I played with the script but I m not sure the based works.

the goal is to import a .skp (it's a projector). as I m not able to load I open a new file with the good projector shape.

        Sketchup.open_file "C;/Program Files/Google/Google SketchUp 7/Plugins/Projectors/ProjectionDesign_F12.skp"

After that, I create the pyramid of projection using specific parameter.
at the end I would like to move and rotate everthing. But I rotate only the pyramid I would like to merge the 2 group but as the Projector group is not loaded but as open file, I have not the hand on it

    # create group 
    group1 = ent.add_group projection_surface.all_connected
    group1.name = "pyramid"
    
    # scale
    s = Geom;;Transformation.scaling [0, 0, 0], scale_factor, scale_factor, scale_factor
    ent.transform_entities s, group1
    
    
    # rotation
    rh = Geom;;Transformation.rotation [0, 0, 0], [0, 0, 1], heading
    rp = Geom;;Transformation.rotation [0, 0, 0], [0, 1, 0], pitch
    rr = Geom;;Transformation.rotation [0, 0, 0], [1, 0, 0], roll

    ent.transform_entities rh, group1
    ent.transform_entities rp, group1
    ent.transform_entities rr, group1

thanks

hello,
nothing works
I quite sure, the base of my code is ugly
could you help me to start with somthing well

Hello,
short introduction
I m seb I live in paris. I use Sketchup as a 2D/3D modeler for my design (pro) My job is to design complexe projection system.
usually we used Rhino 3D. But sketchup seams to be interesting with the ruby script or C++ API.
I m not sure I can do everything, but It's a good start
I developted 2 plugins : Generic projector, parametric cylinder
thx
seb

Thx I will try tomorrow

thx
I created several faces.
I want ti select all and put in a group and after move the group

Hello,
I m a newbee
couple of weeks, I start to dev using the ruby API
For my plugin create a projector and all the parametric pyrammid
I have 2 problems

• I m not able to do the same think as File/import a skp file. I have to create a new one using the folloing

Sketchup.open_file "C:/ANTYCIP/Sketchup components/Projectors/ProjectionDesign_F12.skp"
proj = Sketchup.active_model.entities.add_group

someone has a idea please?

• after my creation, I want to put every body un a group and manupilate the group (translation / rotation / scale
  I m not able to add some thing or everything in a group

create group

group1 = ent.add_group projection_surface.all_connected (bad fonction)
group1.name = "pyramid"

idea

thanks a lot
