## Inspect a Process Modeling product

Use **PM product gadget** to answer where a Process Modeling product is in its flow,
which product type and component it uses, and whether it currently has an
assembly, feed, or transport relationship.

An in-assembly product identifies its containing assembly in **In Assembly**.

With the transport-solution overlay enabled, the 3D view labels the selected product and its route context.

## Before you start

* Select a runtime Process Modeling product, or a component whose `Product`
  relationship is populated
* Run the model far enough to create runtime products when the layout starts
  without any products

## Steps

1. [Open Inspector](https://inspector.4111778.xyz/docs/getting-started/open-inspector/) for the selected
   product or component.
2. In the gadget selector, select **PM product gadget**.
3. Read **Product Object**, **Product Type**, and **Component** to confirm that
   Inspector is showing the intended product.
4. Check **Is Assembly** and **In Assembly** when the question concerns
   containment or an assembly product.
5. Check **Current Flow State** and **Next Flow Info** to identify the current
   process-flow position and the next flow information exposed by the model.
6. Check **Product Feed** and **Transport solution** to investigate the
   product's current matching and transport relationships.
7. Use the overlay control beside **Transport solution** to show or hide the
   current transport links and nodes in 3D. Use the overlay control beside
   **Flow History** to show or hide the product's flow-history path.

## Interpret the result

* **Product Object**, **Product Type**, and **Component** identify the runtime
  object and the model objects associated with it.
* **Is Assembly** is `True` for an assembly product. **In Assembly** identifies
  a containing assembly when one is found; it can be `<null>` when the product
  is not in an assembly.
* **Current Flow State** and **Next Flow Info** are inspectable Process
  Modeling objects. Use their inspect actions when the state or next step needs
  more detail than the summary row provides.
* **Product Feed** is the feed matched to the product, when one exists. A
  `<null>` value means no current feed relationship was returned for the
  selected product.
* **Transport solution** is the current transport solution, when one exists.
  A `<null>` value means the selected product has no current transport solution
  in that state; the transport overlay has nothing to display until a solution
  is available.
* **Flow History** can visualize recorded flow events and product-type changes
  for the inspected product. The visualization service ignores visit-count
  reset records and uses the recorded world positions for the remaining path.

## Selection and simulation notes

The gadget can inspect a direct `ISimProduct`, a component with a non-null
product, or an object selection containing either. With a multi-selection, the
summary rows use the first eligible product while flow-history visualization can
track all eligible products in the selection.

The values shown by the gadget describe the selected product's current
simulation state. A relationship row can be `<null>` when that relationship is
not available for the selected product at that time; this does not indicate a
missing gadget.

gadget. Use [Object hierarchy](https://inspector.4111778.xyz/docs/gadgets/object-hierarchy/) to inspect the selected
product's simulation-object context, or [Object bounds](https://inspector.4111778.xyz/docs/gadgets/object-bounds/) to
check the associated component's dimensions and placement.
