require ‘sketchup.rb’

Directory containing SketchUp models

Directory to save the exported DXF files

Function to save view as a 2D DXF file

:export_hidden_geometry => true,
:projection => “Parallel”
}
model.export(filename, options)
end

begin

Close all open models

Sketchup.active_model.close(true) while Sketchup.active_model

Iterate through all .skp files in the input directory

It would be great help if someone can tell me what is causing issue ?

It would help if you post code in the forum correctly …

(1) Probably you are putting the API into an endless loop with …

  • Sketchup.active_model.close(true) while Sketchup.active_model

(2) SketchUp native 2D DWG or DXF export is not exposed to the Ruby API.

(3) Path strings do not use double forward slash characters. Single slash only.
Or double backslash (which is an escaped backslash.)

To get a file directory … usually we use UI.select_directory

AND …

(4) Please do not define local variables or methods in the top-level ObjectSpace, which actually within a special instance of Object

(5) These are not valid export options for any file format. See the documentation:

(6) This may not work well the way it is written.

It will show a modal error message box if the file cannot be found or perhaps an exception. So, file IO operations should normally be wrapped up in a begin … rescue … else … end block.

You should also use the newer overload to prevent deprecated warnings output to console …

      status = Sketchup.open_file(file_path, with_status: true)

SketchUp will try to always have a valid model object but this method does not return a model reference. So, you will need to get the model reference if no error occurred:

    begin
      status = Sketchup.open_file(file_path, with_status: true)
    rescue => error
      puts %[Error opening file "#{file_path}"]
      puts error.inspect
      next # skip to next file
    else
      model = Sketchup.active_model
    end

(7) The Sketchup module does not have a method named close_active_model !

… perhaps the AI meant:

      Sketchup.active_model.close

… but, your code made changes to the model, so the user would get a modal message box asking whether to save changes. To bypass this message box and discard changes, use …

      discard_changes = true
      Sketchup.active_model.close(discard_changes)

(8) Your code added scene pages to the model (without first checking if those pages exist.) Then the code did not ensure that the proper page was activated before changing the camera.

Adding a page will automatically make it the selected_page. So, adding the top_scene should be placed after setting the front_camera and just before setting the top_camera.

(9) Your code did not set either camera’s perspective type:

      front_camera.perspective = false

(10) Ask yourself is it really necessary to even create new scene pages just to export a view with a certain camera setting ?

Thanks Dan! for your suggestions.
