What is an Intermediate Throw Event?

A None Intermediate Throw Event represents a process milestone without any triggering behavior. When the token reaches this event, it passes through immediately-useful for marking significant process states or checkpoints.

Visual Representation

The event shows a double-line circle that is empty inside (no icon). The double border indicates intermediate positioning; the empty interior shows no specific trigger or action.

Key Characteristics

  • No trigger or action: Token passes through immediately
  • Milestone marker: Documents significant process states
  • Monitoring hook: Provides a point to capture metrics or status
  • Visual checkpoint: Helps readers understand process progression

Common Use Cases

Mark the "Order Confirmed" milestone for tracking progress through the fulfillment process.
