Create a group and manipulate add geom

Skippy1974

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

model.definitions.load will let you import components.

I am not entirely sure what you are trying to do here...
You want to import multiple components into group?

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

TIG

All face geometry and intended group must be in the same context ['entities'].
Make an array of the faces ['faces'].
To make a group use...
group=faces[0].parent.entities.add_group(faces)
You can now change the group.name, group.layer, group.material etc.
To move the group to a new point...
pt=Geom::Point3d.new(1,2,3) ### or whatever x/y/z is required
tr=Geom::Transformation.new(pt)
then
group.transform(tr)
The 'group' is now at 'pt'...

If you are creating all the geometry your self, then create the group first, then add the geometry directly into the group. It a different approach than when you model where you create geometry and then group.

Thx I will try tomorrow

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

Could you please be more specific? Error messages? Unexpected behaviour? (If so, what is expected?)

Skippy1974

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

thomthom

You are opening the file because you could not load it as a component? Why did you not investigate to why you could not load the component?
hmm.... model.definitions.load did you perhaps assume would insert an instance of the component? model.definitions.load only loads the .skp into the model - you then have to place it in the model afterwards.

model = Sketchup.active_model projector_def = model.definitions.load "C:/Program Files/Google/Google SketchUp 7/Plugins/Projectors/ProjectionDesign_F12.skp" t = Geom::Transformation.new # This will load the component to the origin [0,0,0] projector = model.active_entities.add_instance( projector_def, t )

Skippy1974

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