How to import several models to designated positions
-
If the models are not SketchUp models, look at:
Model.import

Take a look at entities.add_instance:

and the DefinitionList, especially DefinitionList.load and DefinitionList.load_from_url:

KarenI got it. Thanks very much!

I test the code, it works well. Thanks!
But now I find a problem about the given coordinate which is designated by me. After importing the model, the position of the model may not be the one I designated. This is because of the file I want to import. Use the Bed.skp file as an example. Suppose I have two Bed models as these in the attachment, if I import them into sketchup with the same given coordinate, after importing, however, the positions of them are not same.
I want to import model with its center at given coordinate in sketchup, no matter where the model is in the import file. Is there any way to implement it?
-
Ah, then you would find the centre of the imported model based on its bounds - and work out where its origin is relative to this centre.
-
Why not get the selected component instance BEFORE you deactivate the MoveTool ???
Then you can get the instance's definition without all that search part.
AND... There IS a standard Ruby module
Test
(and the API added a few methods in there,) that should really not be modified.Something like this... wrap inside a module
Temp
, or at the very least, in a submodule ofTest
, such as...Test::Import

There is a
Test
module part of the Ruby that ships with SketchUp?YES. And.. John H & Co. added test methods to it:
Test.methods(false).sort
%(#000000)[>>] %(#008000)[["AutoClickTime", "AutoClickTime=", "AutoDragDistance", "AutoDragDistance=", "CorruptModel", "FindFile", "eat_mem", "face_to_mesh", "flip_images_for_origami", "project_textures_from_photo", "show_fps", "time_display", "time_pick", "use_sg_off_screen", "use_sg_on_screen"]]
This is the same module that gets defined when you use the Standard Library Extension for unit testing. However.. in this case the
Test
module is only used as a namespace. (That is not to say that other library extensions, might add methods to moduleTest
.) -
flip_images_for_origam

When I first listed the methods, I thot for a moment (until I looked twice,) that the seventh method was named
