Selection of the three points

Beppe64 · October 23, 2019, 2:39pm

Hi, take a look at the attached video, taken from a plugin,
can you kindly give me precise directions, where to look
in the Ruby API manual, to get the same result…
selection of the three points…
point on the face…
point of origin or departure…
second point along horizontal axis…
Third Point along vertical axis…created the point…

Thank you

Joseph.

You need to download the Ruby examples and study the files.

https://extensions.sketchup.com/en/content/example-ruby-scripts

"linetool.rb" in particular in the "su_examples" folder.

Also, study these others …

https://extensions.sketchup.com/en/content/utilities-tools
https://extensions.sketchup.com/en/content/rotated-rectangle-tool

And there are more by the SketchUp Team.

One more thing, Mr. Dan…

and the folder “su_examples”… is located…??

Thank you

Joseph.

Mr. Dan…I found everything,
in the “plugins” folder of Sketchup…

Thanks again.

Joseph.

RBZ files are really ZIP archives. You can unzip them into a Documents subfolder so they are easier to find for study.

The example extensions isn’t maintained any more. It’s likely they’ll be removed from EW and migrated to GitHub.

Newer examples can be found in this repository:

A verbose example (tutorial) of a simple tool can be found here:

module Examples
  module CustomTool

    # Custom tools create a class which responds to various callback methods
    # from SketchUp.
    class LineTool

      # The `actvate` method is called whenever the tool is activated. This is
      # where you initialize and prepare your tool.
      # Note that this is different from Ruby's `initialize` method. You can
      # reuse Tool instances in which case `initialize` would not be the best
      # place to set up the tool.
      def activate

        # We will need to sample 3d points from the model as the user interacts
