Open walterbender opened 6 months ago

We have support for a "hollow line" in the JavaScript version of Turtle. It appears on the Pen Palette and implemented in the Turtle Painter code.

The block is really useful for 3-D printing, where you can directly extrude from the exported SVG using programs like TinkerCad.

Josh Burker has lots of fun lesson plans that use this feature:

The goal here is to provide similar functionality to the Python code.
