This page collects a list of short (1-3 sentences) tips for using OpenRocket. Later on they may be included in the software as a "tip of the day" system.
- You can type in equations in the entry fields instead of numbers. For example, to double a length you can type 3.1*2.
- The component tree will display any component comments as tool tips. You can set the comment on the Comment tab of the component configuration dialog.
- If you want to always load a specific .ork file, you can specify the filename as a command line argument when starting openrocket.
- Motors can be attached to either body tubes or inner tubes. You can attach one on the Motor tab of the configuration dialog.
- You can configure all motor selections by selecting Edit configurations from the Motor configuration dropdown.
- You can scale a single component or an entire design using Edit → Scale...
- You can define custom materials by selecting Custom from the bottom of a material selection list.
- You can select ready components from the preset dropdown on the top-right of the component editing dialog. Tick the box in the table to add the component to the dropdown menu.
- You can select components by clicking them in the diagram, or edit them by double-clicking.
- To get the best accuracy possible, you can weight your components and enter the override the calculated weight on the Override' tab when editing components.
- You can define through-the-wall fin tabs on the Fin tabs tab when editing a fin set.
- Your rocket's surface roughness can affect flight altitude significantly. Select the appropriate roughness on the Component finish dropdown. You can set the same finish for all components by clicking Set for all.
- You will see immediate results of a flight simulation on the lower-left corner of the design diagram. This reflects a flight with your currently selected motor configuration.
- In case OpenRocket cannot reliably compute the aerodynamic properties of the rocket, you will see warnings on the lower-right corner of the design diagram.
- You can create clustered rockets easily using the Cluster tab when editing Inner tubes. Any motors or components attached to the inner tube will be present on all copies of the inner tube.
- Centering rings, Engine blocks, Couplers and Bulkheads can automatically compute the relevant dimensions from the other components when the Automatic checkbox is selected.
- You can simulate launch rails or pins by creating filled launch lugs of the corresponding size.
- Only body components and fin sets affect the aerodynamics of the rocket. Even if an internal component extrudes outside of the body tube, its effect will not be taken into account in simulations!
- You can add stages to your rocket by pressing New stage on the main screen. Stage separation is configured on the Separation tab when editing a stage.
