I have created a custom tool that allows users to select an edge and a point. When the user moves the mouse, one endpoint of the edge will move along with the mouse. The selected point is marked as @ip1. If @ip1 is not located on the edge, its position will not change. However, if @ip1 is located at…

I tried to run this, but I’m not sure what I’m supposed to do to reproduce what you’re seeing. Can you add some screenshots or a video capture to illustrate?

[image] killernova: mod.entities.transform_entities(tr, @vertex) this should be view.model.entities.transform_entities(tr, @vertex) Then I suggest to modify the draw method to visualise better: e.g.: def draw(view) @ip.draw(view) view.draw_points(@ip1.position, 10, 1, "red"…

[image] killernova: mod.entities.transform_entities(tr, @vertex) Sorry, mod is an instance method defined in the Object class in my code base, I just forget to replace it with Sketchup.active_model And yes, your video shows what I’m confusing.

[image] killernova: I just forget to replace it with Sketchup.active_model As I mentioned above you can use: the View #model method to retrieve the model for the current view.

[image] killernova: Sorry, mod is an instance method defined in the Object class in my code base, I just forget to replace it with Sketchup.active_model DO NOT modify Ruby Core classes or SketchUp API classes ! SketchUp Ruby is a shared environment and doing this this will effect ALL other e…

Thanks for your advice. I know that the code for this tool is incomplete and not rigorous, and I am not trying to create a MOVE tool. As the name suggests, this is just a temporary test tool created to demonstrate a somewhat strange behavior of Sketchup::InputPoint#pick method. Thanks anyway.

[image] DanRathbun: With recent Ruby versions warnings will be output if an object has not defined @instance variables before accessing them. In older versions of Ruby nil would be returned when accessing uninitialized @variables. But this is no longer the case. I searched on Google and didn’…

[image] DanRathbun: [image] killernova: @ip1.pick(view, x, y) # Here is the only place to change @ip1 vertices = @edge.vertices.sort do |a, b| a.position.distance(@ip1.position) <=> b.position.distance(@ip1.position) end @vertex = vertices.first This might be simplif…
