FYI ... Julia Eneroth has released her own edition of this feature that uses the SketchUp 2023 (and later) Overlay feature. So, for those that despise popup windows, you can see the instance path as a text overlay upon the model view instead.

@Dan-Rathbun said in C SDK save in 2022 or 2023 formats:
What is different in the v22 and v23 file formats that need to be maintained?
I took a quick look at the release notes and I see only 2 new features that would be saved into the SKP file data:
v23 : Added Ruby Overlays and the model now has a flag collection with a Boolean state for overlays.
v24 : Added the Ambient Occlusion style properties (a state flag and numeric setting.)
Opening a SKP file on any older version back to 21 would just ignore any unknown data. This is known as SketchUp's versionless format since v21.
So WHY would you need to backsave to what v22 or v23 saved as ?
Ie, v22 did not add any new features that made the SKP any different from what v21 saved.
And, v23 only adds the listing for the overlays collection and would just ignore the new AO style attributes (added in v24) it does not know about. It might leave the attributes as is within the model data but do nothing with them, OR ignore them so as to not write them out when it saves a v23 SKP.
I think it is expected that you use SUModelSaveToFileWithVersion() with a SUModelVersion_SU2021 constant.
What is different in the v22 and v23 file formats that need to be maintained?
The only other thing I can think of is to compile 2 external utilities with old versions of the SketchUp SDK and have these utilities backsave the SKP files using the SUModelVersion_Current constant.
If it does not work using onLButtonDown then try renaming the callback to onLButtonUp. I recall back in the v8 days there were some quirks with one or the other callback method (I think on Mac platform mostly.)
@robertWan said in AI-Created Extension for SketchUp – Issues with CTRL Modifier Functionality:
Using
Sketchup::InputModifier::CTRLto check if the CTRL key is pressed.
Where did you get Sketchup::InputModifier::CTRL from? This is NOT a constant defined by SketchUp's Ruby API. Nor is there an InputModifier submodule. Be careful as the AIs have been known to just "invent" coding objects or functions to satisfy themselves in providing "solutions" (which are not guaranteed to work.)
FYI, the toplevel constants defined by SketchUp's Ruby API are listed at: Top Level Namespace
In the tool's onLButtonDown callback method, I think you should be using COPY_MODIFIER_KEY or COPY_MODIFIER_MASK instead of MK_CONTROL to test the flags passed in by the SketchUp engine. See the Sketchup::Tool abstract class overview.
Also, your extension submodule should be wrapped within a unique top-level namespace module. Ie:
module RobertWan # top-level namespace
module CustomSelectionTool # extension submodule
class SelectPlaneTool
# ... the tool code ...
end
def self.activate_select_plane_tool
Sketchup.active_model.select_tool(SelectPlaneTool.new)
end
if !file_loaded?(__FILE__)
UI.menu('Plugins').add_item('Select Plane Tool') {
CustomSelectionTool.activate_select_plane_tool
}
file_loaded(__FILE__)
end
end # extension submodule
end # top-level namespace
I did search this category but got no hits.
Discourse forums allow setting a size for images via the addition of a pipe character and size following the image filename within the square brackets, viz:
But specifying size this way is not honored by SCF's forum software.
Is there some other way?
@Gábor ?
@Jorgensen said in Parametric Modeling - development?:
I've been jealous of the users of Rhino for some years - that they have the node based tool - grasshopper.
I think node based modeling could be a big think for Sketchup, but it seems development stopped back in 2021, witch I find sad....
Sorry, Cannot help with contact.
But SketchUp Live Components and the Trimble Creator have not been abandoned AFAIK.
Discussion is still happening in its SketchUp Labs subcatgeory.
Purpose: Brings together extension dialogs scattered on multiple screens or possibly lost offscreen. May be a benefit to users with notebook docks or who move their machine between locations with differing display setups.
Will not work on native web-based dialogs such as 3D Warehouse, Extension Manager, etc. (These windows are hidden from the API.)
NOTE: SketchUp 2024 has may have had some fixes that can natively detect lost dialogs and move them back onto an active display. This extension is meant for older versions that do not have this fix or possibly as a complement for when the native fix might fail.
Localization: localized for SketchUp supported languages (and nl & uk.)
Adds a menu item to the Window menu.
Provides a toolbar with a button: 
Tested on MS Windows platform. Version 2024, 2023, 2022, 2021, & 2017.
I tried to write this so it might possibly even load under Ruby 1.8 for versions prior to SU2014.
But no guarantees for such old versions. (I do not have a machine ready that can run these old versions and I'm not really interested in trying to test for them.)
@paulofukuta said in [Plugin] Multiple Component Edit Warning:
When I install the Edit Flag v2.4.0 plugin in SketchUp in Brazilian Portuguese, the tool name does not appear. How could I fix this bug?
There were unicode character bugs in some of the language files resulting in silent failures for the menu command labels.
I fixed all the bugs in the language files with version 2.4.2 (see below).
@elijahpekaar said in [Plugin] Multiple Component Edit Warning:
@ashscott Is there a possibility of getting an updated version for 2024 sketchup?
I am the author of Ash's extension. (He hasn't been here in almost 2 years and not posted in the forum for almost 7 years.)
Changes for SketchUp 2024 and Ruby 3:
Updates specific to SketchUp 2024+ and Ruby 3.2:
- Changed File.exists? call to File.exist?
Re-focus the Sketchup window, so that the Edit Flag warning dialog no longer seizes the focus from the main modeling window.
Fixed the scrollbars showing in the edit warning dialog.
Added system font identifiers for both platforms to the "font-family" style for the dialog. The text should now show in the system font.
Localization:
- Fixed unicode characters in files: es, fr, it, pt-BR, pt-PT
- Added language hash files: cs, ko, ja, pl, sv, uk, zh-TW, zh-CN.
- Localized the extension description and name for the Extension Manager.
The extension is now signed.
@Sklik-Rab said in Ruby Sketchup Programmatic Union of Multiple items:
@Dan-Rathbun
How to check if @union become nil?
To check if the reference points at nil, you can use:
@union.nil? which is inherited by Array from Object#nil?
To check if the array is empty, you can use:
@union.empty?
@rcatedra I myself do not use this library. So, I cannot say for sure.
But the error given is that the module does not respond to a method named "key".
If it did respond to this method in the past under older SketchUp versions, then the reason for SU2024 is that an error during loading prevented the module code from defining its methods.
@TIG Good to know. (I did not see mention of the issue.)
The migration to the new software has broken all the code snippets (both inline and code blocks.)
Punctuation characters have been replaced with HTML Character entity codes.
So, this new forum uses markdown instead of bbCode ?
FYI, SketchUp has migrated to using the Qt GUI framework libraries. So, in many cases it is no longer possible to use the Windows SDK system calls to tweak SketchUp interface objects.
The C API is mainly written to act upon files.
There is only some limited things you can do with "live" models.
Currently, the C API cannot be used to modify the active model.
You can get the active edit path via: SUModelGetActivePath()
... and from it the transform via: SUInstancePathGetTransform()

I know this post is like a thousand years old, but I was using the "extract_png.rb" from "Jim". It doesn't seem to work in SU2023. I need this to compile a catalogue of all of my components. Is there an updated version out there somewhere? I really need this. Thanks in advance!
If you are doing this from within SketchUp, try something like:
# SketchUp 2015 or later.
def export_thumbnails(source_path = nil, dest_path = nil)
#
unless source_path && File.directory?(source_path)
models = Sketchup.active_model.path
if models.empty?
models = File.join(ENV['HOME'], 'Documents')
end
#
source_path = UI.select_directory(
title; "Select Model Directory",
directory; models
)
return unless source_path
end
#
unless dest_path && File.directory?(dest_path)
images = Sketchup.active_model.path
images = source_path if images.empty?
#
dest_path = UI.select_directory(
title; "Select Image Output Directory",
directory; images
)
return unless dest_path
end
#
Dir.glob( '*.skp', base; source_path ) do |skp|
source_file = File.join(source_path, skp)
image_file = skp.split('.')[0] << '.png'
output_file = File.join( dest_path, image_file )
Sketchup.save_thumbnail(source_file, output_file)
end # Dir loop
#
end ###
@areal3d said:
hello,
how can i get the whole path as in the pickhelper from a selected instance?
You will either need to build an InstancePath as you drill down or get the Model.active_path and add the selected instance to it.
@areal3d said:
hello,
... now when I iterate thru entities of a certain instance and want to get the parent, i do not get the higher INSTANCE, but the DEFINITION LIST.
Instances do not have Entities collections. Only definitions and the top-level model have an Entities collection.
@tig said:
In the very first line of your Ruby RB file add this.
# encoding; UTF-8
This should ensure your own code is properly formatted.
This magic comment does not ensure that the code file is saved as UTF-8 w/o BOM.
This must be set in whatever code editor is being used.
