Get X,Y,Z of active_model with Ruby

kimpastro

Hi, I swear I do a lot of research about this issue but can't find anything or can't understanding anything about what I've found.

Just need to get the value of x,y and z of a active_model, because i'm gonna to export the project in json format and need when import to continue with they respective position.

Ex:
my_model['x'] = Sketchup.active_model.getX
my_model['y'] = Sketchup.active_model.getY
my_model['z'] = Sketchup.active_model.getZ

the getX getY and getZ is what i need.

If someone could help me or just link a topic about this explanation, will help me a lot.

thanks so much guys.

Your cod-example is very very unclear.
What " XYZ" of the 'model' are you seeking ?
Please explain yourself better...

I'll throw in some ideas that might help, meanwhile...

bounds = Sketchup.active_model.bounds
center = bounds.center ### the center point of the model's bounding box, which includes XYZ coordinates.
min = bounds.min ### the minimum point of the model's bounding box, which includes XYZ coordinates.
max = bounds.max ### the maximum point of the model's bounding box, which includes XYZ coordinates.
xdim = bounds.width ### the width [X/red] dimension of the model's bounding box, in inches.
ydim = bounds.height ### the height [Y/green] dimension of the model's bounding box, in inches.
zdim = bounds.depth ### the depth [Z/blue] dimension of the model's bounding box, in inches.
### to get the three x,y,z values in inches [aka Float] of a point3d reference use...
x,y,z = point.to_a
### to get a single coordinate value in current model-units [aka Length] of a point3d reference use...
x = point.x
### etc... there are lots of permutations...

TIG, first of all thanks for reply.

I misunderstood the whole thing.
The "model" I've mentioned actually is the entity that contain all children entities.

What I do was something like that:


if not is_children?
position; {
  x; entity.transformation.origin.x,
  y; entity.transformation.origin.y,
  z; entity.transformation.origin.x
}
end

Thanks again, the bound method that you've explained, resolved a few other things.

The origin of the active_model is [0,0,0], which is referenced as ORIGIN.

If the model came from Google Earth, then the real world co-ordinates (in inches) will be in the GeoReference attribute dictionary.


mdl = Sketchup;;active_model
if mdl.georeferenced? &&
!mdl.attribute_dictionary('GeoReference',false).nil?
  [
    mdl.get_attribute('GeoReference', 'ModelTranslationX', 0.0),
    mdl.get_attribute('GeoReference', 'ModelTranslationY', 0.0),
    mdl.get_attribute('GeoReference', 'ModelTranslationZ', 0.0)
  ]
else
  ORIGIN.to_a
end
