Description
Fins are used to aerodynamically control the direction of flight.
Usage
- There are several ways to invoke the command:
- Press the Fin button.
- Select the Rocket → Fin option from the menu.
- Double click on a Fin object in the model view.
- Set options and press OK.
Options
- Optional. List the command options here. Check out two examples, Draft Line and PartDesign Pad.
Example
Optional.
Notes
- Optional. Use a bullet list if there are multiple items. You can also mention limitations here.
Properties
Rocket Component
These parameters are provided for information and have no effect on the design of the component.
- DataManufacturer: Manufacturer when known
- DataPart Number: Manufacturer part number
- DataDescription: Description of the component
- DataMaterial: Material when known
Nose Cone
- DataFin Type: Defines the shape of the fin. At the moment, only Trapezoidal fins are supported.
- DataHeight: The fin height.
- DataSweep Length: The distance from the front of the fin root to the front of the fin tip along the x axis. This may be negative. Setting this value will cause the Sweep Angle to be adjusted.
- DataSweep Angle: The angle of the front of the fin, with a vertical front being 0 degrees. This may be negative. Setting this value will cause the Sweep Length to be adjusted.
- DataFin Root Cross Section: The cross section shape of the fin at the root, see Options
- DataFin Root Chord: The distance between the fin leading and trailing edges at the root
- DataFin Root Thickness: Maximum thickness at the root of the fin
- DataFin Root Use Percentage: Expresses the Fin Root Length 1 and Fin Root Length 2 properties as a percentage of the Fin Root Chord
- DataFin Root Length 1: Usage depends on the Fin Root Cross Section and will apply to a taper length or similar, see Options
- DataFin Root Length 2: Usage depends on the Fin Root Cross Section and will apply to a taper length or similar when multiple values are required, see Options
- DataFin Tip Cross Section: The cross section shape of the fin at the tip, see Options
- DataFin Tip Chord: The distance between the fin leading and trailing edges at the tip
- DataFin Tip Thickness: Maximum thickness at the tip of the fin
- DataFin Tip Use Percentage: Expresses the Fin Tip Length 1 and Fin Tip Length 2 properties as a percentage of the Fin Tip Chord
- DataFin Tip Length 1: Usage depends on the Fin Tip Cross Section and will apply to a taper length or similar, see Options
- DataFin Tip Length 2: Usage depends on the Fin Tip Cross Section and will apply to a taper length or similar when multiple values are required, see Options
- DataTTW Tab: True when a tab for Through the Wall fins is required, see Options
- DataTTW Offset: Distance from the front of the fin to the front of the TTW tab
- DataTTW Length: Length of the TTW tab
- DataTTW Height: Height of the TTW tab
- DataTTW Thickness: Thickness of the TTW tab
Scripting

The ExampleCommandModel tool can be used in macros and from the Python console by using the following function:
Object = makeExampleCommandModel(Data1, Data2)
- Creates an
Object
usingData1
andData2
.
Example:
import FreeCAD, Base
Model = Base.makeExampleCommandModel(FreeCAD.Data1, FreeCAD.Data2)
