Description

A Centering Ring is a solid object used to hold one or more body tubes inside another body tube.

Conical

Usage

  1. There are several ways to invoke the command:
    • Press the Centering Ring button.
    • Select the Rocket → Centering Ring option from the menu.
    • Double click on a Centering Ring object in the Tree view.
  2. Set options and press OK.

Options

Notch

Centering rings, especially those used for low power rocketry, often need a notch to accommodate an engine hook. The Centering Ring tool can generate those for you.
