Thank you very much, this is exactly what I'm looking for !

Hello everyone,

I would like to "cleanly" code small extensions for SketchUp.

Is there somewhere an empty code template with best practices ? with comments that say "you have to put (this) here"

For example, I'm wondering about :

• how many folders ?
• where (folder) to put toolbar icons, what formats are supported ?
• where to put menu descriptions in the code ?
• how to separate the code into different files ?
• which "containers" to use in the code ?

I'm not a strong coder, so I'm sorry if these questions seem trivial.

Do you have anything like this to hand?

Thank you for your help,
Renaud

Hi @thomthom and folks,

I just managed to insert custom cursors to this usefull plugin.
Attached are the .png files.
The images are in the same folder than "core.rb"

And this is the code :

def initialize(settings)
      @settings = settings
      
		folder_path = File.dirname(__FILE__)
		
		cursor_name = 'cursor_select_curve.png'
		cursor_select_curve_path = File.join(folder_path, cursor_name)
	   @result = File.file?(cursor_select_curve_path)
	   unless @result
		  msg = "Can't find the 'cursor icon' path"
		  UI.messagebox(msg, MB_OK)
		  return
		end
		
		cursor_name = 'cursor_select_curve_plus.png'
		cursor_select_curve_plus_path = File.join(folder_path, cursor_name)
	   @result = File.file?(cursor_select_curve_plus_path)
	   unless @result
		  msg = "Can't find the 'cursor icon' path"
		  UI.messagebox(msg, MB_OK)
		  return
		end
		
		cursor_name = 'cursor_select_curve_minus.png'
		cursor_select_curve_minus_path = File.join(folder_path, cursor_name)
	   @result = File.file?(cursor_select_curve_minus_path)
	   unless @result
		  msg = "Can't find the 'cursor icon' path"
		  UI.messagebox(msg, MB_OK)
		  return
		end
		
		cursor_name = 'cursor_select_curve_plus_minus.png'
		cursor_select_curve_plus_minus_path = File.join(folder_path, cursor_name)
	   @result = File.file?(cursor_select_curve_plus_minus_path)
	   unless @result
		  msg = "Can't find the 'cursor icon' path"
		  UI.messagebox(msg, MB_OK)
		  return
		end
		
		@cursor_select        = UI.create_cursor(cursor_select_curve_path, 9, 5)
      # @cursor_select        = TT;;Cursor.get_id( ;select )
      @cursor_select_add    = UI.create_cursor(cursor_select_curve_plus_path, 9, 5)
      # @cursor_select_add    = TT;;Cursor.get_id( ;select_add )
      @cursor_select_remove = UI.create_cursor(cursor_select_curve_minus_path, 9, 5)
      # @cursor_select_remove = TT;;Cursor.get_id( ;select_remove )
		@cursor_select_toggle = UI.create_cursor(cursor_select_curve_plus_minus_path, 9, 5)
      # @cursor_select_toggle = TT;;Cursor.get_id( ;select_toggle )
		
      @ctrl   = false
      @shift  = false
    end

(I'm not good in Ruby, sorry)

Hope this helps.

Hello @thomthom, thank you very much for this very usefull plugin.

Is there a way to add a modified cursor? (I can draw it if you tell me the specifications.)

Thank you very much for this explanation and for the special case.
It helps a lot.

Hello,

I'm creating faces with 3 points :
face = model.entities.add_face(pts)

Could you tell me if there is a way to know the orientation of the face according to the "direction of the rotation" between the 3 points?

Thank you very much.
Renaud.

Hello,

If the making process of a component is a duplication by symetrical operation, then "make unique", the axis are inverted.
(Sorry for this bad english! )

This is a problem for me for a plugin containing arcs exportation.

Do you know how to test the orientation of the axis and how to change it temporarely in my calculations if it's not direct (red, green, blue)?

I think it must be here in my code :

# Recursively export faces and exploding groups and components
def self.write_content(file, selection, tform, z)  # if z==1, it's a 3D export file, if z==0, it's a 2D export file (all the Z values are equal to "0.0" and the normal.z is equal to "1.0"
   selection.each do |entity|    
      if entity.is_a?(Sketchup;;Face)
      transform_vector_of_group(entity.normal, tform)
         if z == 1 || (z == 0 && transform_vector_of_group(entity.normal, tform).parallel?(Z_AXIS) && transform_point_of_group(entity.vertices[0].position, tform).z.abs < 0.001 ) # Sketchup tolerance ; 0.0001 inch
            $number_of_exported_faces +=1
            write_face(file, entity, tform, z)
            result = Sketchup.set_status_text $number_of_exported_faces.to_s, SB_VCB_VALUE
         end
      elsif entity.is_a?(Sketchup;;Group) || entity.is_a?(Sketchup;;ComponentInstance)
         if entity.is_a?(Sketchup;;Group)
            definition = entity.entities.parent
         else
            definition = entity.definition
         end
         write_content(file, definition.entities, tform * entity.transformation, z)
      end
   end
end

Thank you very much.
Renaud.

Thank you very much for these complementary solutions.

Renaud.

TIG, your solution is working fine. Thank you very much.

@jim said:

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

Yes Jim, not working.

BR,
Renaud.

OK, will try it. Thank you!
