Nose cone dialog

The Edit Nose Cone Dialog in SpaceCAD 7 allows users to customize the design and properties of the nose cone, a critical rocket element that affects both aerodynamics and stability. This dialog offers several adjustable parameters, including material, shape, dimensions, and internal structure, to suit different design needs.

Key Fields and Features:

Nose Cone Name and Color

• Name: Displays the name of the selected nose cone (editable field).
• 2D Color: Allows users to choose a custom color for the 2D design view of the nose cone.
  • Custom Color Selector: Provides various options for 2D color customization, improving visibility and differentiation within the design.

Load from Database

• Load from Database: Provides access to a pre-defined list of nose cone designs from SpaceCAD’s parts database.

• Users can import designs directly from the database, saving time and using common industry-standard nose cones.

Material

• Displays the material used for the nose cone (e.g., Balsa).
• Change Button: Allows users to select different materials for the nose cone, such as plastic, wood, or composite materials, which affect weight and strength from SpaceCAD’s material database.

Weight and Center of Gravity (CG)

• Fix Weight at: Allows users to set a fixed weight for the nose cone (editable in grams).
• Fixed CG Position at: Users can manually set the Center of Gravity for the nose cone, optimizing the rocket’s overall stability.

Dimensions and Shape

• Shape Length: Sets the total length of the nose cone.
• Diameter: Specifies the maximum diameter of the nose cone (typically matching the body tube diameter).
• Base Length: Adjusts the length of the base, which can affect the aerodynamic profile.
• Shape Selector: Provides options for selecting different nose cone shapes (e.g., Ogive, Conical, Parabolic). Each shape affects the aerodynamics of the rocket differently.
• Shape Preview: Displays a visual preview of the selected shape, updating as changes are made.

Shoulder Dimensions

• Shoulder Length: Defines the length of the shoulder (the section of the nose cone that fits inside the body tube).
• Shoulder Diameter: Specifies the diameter of the shoulder for a snug fit.
• Autosize Shoulder: Automatically adjusts the shoulder size to match the body tube for a precise fit, ensuring a seamless transition between elements.

Nose Cone Structure

• Filled: Indicates that the nose cone is solid, which provides more weight and strength.
• With Core: Selects a nose cone with a hollow core. Users can adjust the core’s length and diameter for weight reduction or to fit specific internal payloads.
• Hollow: Allows users to set the wall thickness for a hollow nose cone, which reduces weight but may impact durability.

Additional Controls:

• Preview: Allows users to see a 3D preview of the nose cone before applying changes. The preview updates in real-time to reflect any adjustments made in the dialog.
• OK: Saves all modifications and applies them to the rocket design.
• Cancel: Closes the dialog without saving changes.

Example Workflow:

1. Adjusting Nose Cone Dimensions:

   • Open the Edit Nose Cone Dialog by selecting the nose cone in the main design area or element tree.
   • Adjust the Shape Length and Diameter to match your design requirements.
   • Use the Shape Selector to switch between different aerodynamic profiles (e.g., from Ogive to Conical).

2. Modifying Material and CG:

   • Click Change under Material to select a different material, such as switching from balsa to plastic.
   • Set a custom Fixed CG Position to adjust the rocket’s center of gravity and improve stability.
