For example, here's a bit of code I wrote which allows you to right click on a component which you wish to exchange for another component and select the new component to use by simply clicking an instance of it in the drawing.
Heres the code which handles adding a menu option to the UI
class SwapTool
# The activate method is called by SketchUp when the tool is first selected.
def activate
Sketchup::set_status_text("Select replacement component", SB_PROMPT)
end
def deactivate(view)
view.invalidate
end
# The onLButtonUp method is called when the user releases the left mouse button.
def onLButtonUp(flags, x, y, view)
ph = view.pick_helper(x, y) #pick helper deals with working out what you have clicked on
ph.do_pick(x, y)
entity = ph.best_picked
return nil if not entity.kind_of?(Sketchup::ComponentInstance) #if the thing thats clicked on is not a component then do nothing.
Sketchup.active_model.start_operation("Swap components") #tells sketch up that all the next commands will be one undo operation
swap_components(entity.definition) # calls the swap_components method
Sketchup.active_model.commit_operation #finishes the undo operation
Sketchup.send_action("selectSelectionTool:") #tells sketch up to activate the select tool
end
def onCancel(flag, view)
Sketchup.send_action("selectSelectionTool:")
end
end # class SwapTool
As you can see it's pretty simple and concise compared to pascal.
You could possibly use swig to generate bindings to your existing C++ classes automatically

Question
Will
I'd like much better support for scripting. The ruby scripting API for google sketchup is light years ahead of the pascal scripting system used by VW.
See here:
https://developers.google.com/sketchup/docs/tutorial_geometry
For example, here's a bit of code I wrote which allows you to right click on a component which you wish to exchange for another component and select the new component to use by simply clicking an instance of it in the drawing.
Heres the code which makes the swap:
def swap_components(theDef) ents = Sketchup.active_model.selection ents.each { |ent| ent.definition = theDef } endHeres the code which handles adding a menu option to the UI
class SwapTool # The activate method is called by SketchUp when the tool is first selected. def activate Sketchup::set_status_text("Select replacement component", SB_PROMPT) end def deactivate(view) view.invalidate end # The onLButtonUp method is called when the user releases the left mouse button. def onLButtonUp(flags, x, y, view) ph = view.pick_helper(x, y) #pick helper deals with working out what you have clicked on ph.do_pick(x, y) entity = ph.best_picked return nil if not entity.kind_of?(Sketchup::ComponentInstance) #if the thing thats clicked on is not a component then do nothing. Sketchup.active_model.start_operation("Swap components") #tells sketch up that all the next commands will be one undo operation swap_components(entity.definition) # calls the swap_components method Sketchup.active_model.commit_operation #finishes the undo operation Sketchup.send_action("selectSelectionTool:") #tells sketch up to activate the select tool end def onCancel(flag, view) Sketchup.send_action("selectSelectionTool:") end end # class SwapToolAs you can see it's pretty simple and concise compared to pascal.

Perhaps you could also use QT for the user interface.

I'd be happy with ruby, python, or any modern object oriented scripting language.
Kind Regards,
Will
