In that case I would write it like this. You might rescue StandardError also, but rescuing Exception is too broad. You generally want to rescue exceptions starting with the most-specific and work up to the least-specific.

def locked?(filename)
   locked = false
   begin
      file = File.open(filename, "w")
   rescue Errno;;EACCES => error
      locked = true
   ensure
      file.close if file
   end
   return locked
end

if $0 == __FILE__
   p locked?("test.txt")
end

Did you try something like File.writable?("file")?

Wild guess - he started a New model and so the @entities variable now refers to an invalid collection.

hello ,jim
I use Press F5 to starting Sketchup

Which version of SketchUp is being launched? Is the file "SURubyDebugger.dll" located in the correct folder (as in the image for SketchUp 16?)

Does SketchUp start completely, or does it freeze? When started with the debug server, SketchUp will appear to freeze while it is waiting for a "start" or "continue" command from Notepad++.

Is you firewall set to allow connections to SketchUp?

Here is a link to Windows socket errors.

10061 Connection refused.

No connection could be made because the target computer actively refused it. This usually results from trying to connect to a service that is inactive on the foreign host—that is, one with no server application running.

How are you starting SketchUp?

It looks like SketchUp is not running the debug server. Start SketchUp from Notepad++ by pressing the F5 key. This launches SketchUp using this command line:

Sketchup.exe -rdebug "ide port=1234"

If you need to change which version of SketchUp, or the location of SketchUp then edit the "shortcuts.xml" file in the NPP folder.

SketchUp must be started with the debug server enabled before pressing the SketchUp icon from the editor.

Again, this debugger is never going to work well because of limitations in PythonScript for Notepad++ and in the SketchUp debug server.

I have tried to fix your error. Extract the file "sudb.py" and replace it in the "plugins\Config\PythonScript\scripts" folder.

sudb.zip

You can try it by downloading this file.

Extract the .zip and start Notepad++ by clicking the notepad++.exe file inside.

Open a Ruby extension to debug. Press F5 to start SketchUp in Debug mode.

Press the SketchUp Icon in the toolbar - this will start SketchUp and add a new margin in the editor - click on the margin to set breakpoints.

I'm not sure. The actual format of the 3D data is U3D. The Wikipedia page lists some software that can handle U3d. I'm not sure how to extact the U3D from the .pdf.

If you open the .pdf in a text editor, maybe you can search for the 3D data, select it and save it to a separate file. Then try to open it in Meshlab.

I have a question,the notepad++ v6.6.2.is old ,how can I use the script for my notepad

Hi Ying,

I haven't tried it in years. This was more a proof-of-concept than a finished plugin. I was disappointed with the poor integration of the plugin with the Notepad++ user interface. The plugin is written in Python and uses the PythonScript plugin for Notepad++.

I have just now been trying to get this to work on version 6.9.1 but so far have not had success getting Python Script to work.

Right-click a edge and click "Select Lines Parallel"

jf_select_parallel_lines.rb

Maybe try this forum: http://sketchucation.com/forums/viewforum.php?f=50

Do you know about Windows Sticky Keys?

Google Search

(www.google.com)

In Windows 10, go to Settings > Ease of Access> Keyboard for several more options.

10K isn't much. It's probably the embedded thumbnail image changing on each save. You can disable it in the Model Info > File dialog.

You can miminizse the thumbnail size by pointing the camera off into blank space then save the file. That is, if you don't need the thumbnail preview.

Your code is not correct - look at my example more carefully. Layer objects have names. A Layer's name is represented as a String.

You're so close.

Sketchup.active_model.selection.each do |entity| 
  if entity.layer.name == "Some Layer name"
    entity.material = "Red"
  end
end

What you were seeing is the representation of a Layer object. Layer objects have these methods.

Also note the comparison operator in Ruby is == and not =

You will want to check out this Github repository[1]

I hope someone who knows better will correct me, but it is my current understanding that you will need Visual Studio 2010 in order to build compatible .dll files for SketchUp plugins on Windows.

If you pin them, you can drag the tabs at the bottom to order them. Once unpinned, they will be arranged.

I would like the tabs to be at the top of the Tray instead of the bottom. It's just where my mouse naturally wants to go.

Hi Nate - Can you post a small example model?
