A flange wall is a specific type of structural or modeling element described as an attached secondary wall that is dependent on a first wall.
Based on the provided reference, here's a breakdown of what defines a flange wall:
- Nature: It is a secondary wall, meaning it's not the primary structure or element.
- Dependency: Crucially, it is dependent on a main or "first" wall to exist and be positioned.
- Creation Method: It is generated by taking an open cross-sectional sketch and extending it (either by extrusion or sweeping) along a defined path or trajectory.
- Attachment Point: The edge where the flange wall attaches to the first wall can be either straight (linear) or curved (nonlinear).
- Surface Requirement: The surface of the first wall immediately next to the attachment edge does not need to be flat or planar.
Think of it as an added feature or extension that springs from an existing wall, shaped by a 2D profile moved along an edge of that main wall.
Here's a summary of its key characteristics:
| Characteristic | Description |
|---|---|
| Type | Attached Secondary Wall |
| Relationship | Dependent on a First Wall |
| Cross-Section | Open Sketch |
| Formation Method | Extruded or Swept |
| Attachment Edge | Can be Linear or Nonlinear |
| Adjacent Surface | Does not need to be Planar |
Understanding flange walls is important in various design and modeling contexts where secondary features are added to primary wall elements, often in software applications like CAD.
