Database Selection Dialog

The Database Selection Dialog in SpaceCAD 7 allows users to select rocket elements from a pre-configured database, ensuring quick access to industry-standard parts like body tubes, nose cones, and other components. This dialog is typically accessed by clicking the “Select from Database” button in element customization dialogs, allowing users to import and configure elements that fit within their rocket design.

Key Fields and Features:

1. Filter Element List (Search Bar)

• Users can type in the name of a specific element to search for it in the database.
• This is useful when the user knows the exact name or identifier of the part they need (e.g., “Body Tube T-4”).

2. Filtered by Tube Diameter (Automatic Filter)

• SpaceCAD automatically filters the available parts to ensure they are compatible with the body tube.
• Example: If you are selecting a body tube insert or engine mount, only components that will fit inside the selected body tube are displayed.
• Users can remove this filter by clicking Clear Filter, but they must manually ensure the part fits within the desired rocket element after removing the filter.

3. Manufacturer Filter (Left Panel)

• Allows users to filter the list by specific manufacturers, such as:
  • Aerotech
  • BalsaMachining
  • Totally Tubular
  • Estes
• Useful for those who prefer specific brands or need consistency in their designs.

4. Material Filter (Left Panel)

• Filters the list by material types used in the elements, such as:
  • Paper
  • Plastic
  • Kraft Phenolic
  • Fiberglass
  • Blue Tube
• This filter ensures users find materials that meet their weight and structural requirements for specific rocket elements.

5. Element List (Right Panel)

• Displays a detailed list of all available rocket elements based on the applied filters.
• Columns:
  • Description: The part name or identifier (e.g., “Body Tube T-22”).
  • Base Diameter: The diameter of the part at its base.
  • Length: The overall length of the part, important for fitting within rocket stages.
  • Material: The material the part is made from (e.g., Paper, Kraft phenolic).
  • Mass: The weight of the part, which directly affects the overall rocket mass and flight dynamics.
  • Manufacturer: The producer of the part.

6. Select Button

• After choosing an element, users click Select to import the part into their design.
• The selected element’s properties are applied to the rocket, and it fits within the existing configuration based on the rocket’s structure.

7. Cancel Button

• Closes the dialog without selecting any elements or making changes.

Example Workflow:

1. Selecting a Body Tube:

   • Open the Database Selection Dialog from the body tube editor.
   • Use the Material Filter to select Paper and apply the Manufacturer Filter for Estes.
   • Choose a body tube that fits the design (e.g., 18 mm Body Tube from the list).
   • Click Select to apply the body tube to the rocket.

2. Adding an Engine Mount:

   • Open the Database Selection Dialog and ensure the Filtered to Max Diameter option is enabled so that only parts fitting within the current body tube are displayed.
   • If you don’t see the part you’re looking for, click Clear Filter and manually check the diameter to ensure compatibility.
   • Select an engine mount and click Select.

Important Notes:

• Automatic Filtering: One of the most common issues users face is not finding an element in the list. This usually happens because SpaceCAD automatically applies a filter to match the body tube’s diameter. Users can remove the filter using the Clear Filter button but must ensure the selected part still fits into the design manually.

Diagram Explanation:

A diagram or flowchart can be added to explain the filtering process and how different categories like material and manufacturer affect the available choices. Additionally, a visual guide can show how the automatic filter ensures part compatibility with the rocket’s body tube.

This documentation ensures users can efficiently navigate the Database Selection Dialog and import elements into their rocket designs while understanding the importance of the filters applied during the selection process.
