Download and copy the "RadialTools CC 2020.atn" file below to the directory where you currently store your Photoshop actions. This will be something like: "{installation folder}\Adobe\Adobe Photoshop CC 2020\Presets\Actions" Alternatively, the ZIP file contains the same file with a "ReadMe.txt" with installation and help information.

Yes, these actions require the latest version of Photoshop. The more recent versions will likely have the fewest issues but you are welcome to try running them on older versions of Photoshop.
Unfortunately, most of the Radial Tools actions are designed to be used in this specific document size. This is not always as much of a liability as you might think. The Radial Document can be fully embedded in another document and it retains full editability and as the shapes are resolution-independent, the document can be scaled up without image degredation. If there is enough interest, I will write a How-To on how you can do this.
The Photoshop Symetry Tool is designed for Painting / Drawing bitmap images, while Radial Tools is predominently focused on creating precision vector shapes. I do expect some synergy between the two different approaches to Radial design and look forward to seeing how that will work.
