# Digital Twin SDK overview

> Scope of Assets/_MolcaDT in molca-sdk-dt and how it relates to Molca Core.

**Source root:** `Assets/_MolcaDT/` (example repo: **molca-sdk-dt**)

The **Molca Digital Twin (DT) SDK** is a **separate product layer** from the [VR training SDK](/vr/sdk-overview). Both can depend on [Molca Core](/core/runtime-manager) (`Packages/com.molca.core/`) for runtime, settings, and networking primitives where the template wires them.

## What ships in `_MolcaDT`

High-level areas (see [Project layout](/dt/project-layout)):

* **`Code/Scripts/Managers`** — app flow: root, preload, login, main menu, loading, search, floor/material/highlight, machine hierarchy, factory menu, interface shell, application access, version check, etc.
* **`Code/Scripts/Network`** — HTTP/SSE-style integration (`NetworkManager`, `TokenRenewalManager`, API mapper invokers, editors).
* **`Code/Scripts/POI`** — points of interest (`POIManager`, `POIHandler`, follow targets).
* **`Code/Scripts/Handler`** — panel and machine UI handlers (overview, data, working order, taskbar, machine selection, …).
* **`Code/Scripts/JsonMapping`** — JSON mapping assets and evaluation.
* **`Code/Scripts/UI`** — twin-specific UI helpers.
* **`Code/Scripts/Editor`** — tooling, inspectors, scene/bundle helpers.

## Recommended reading path

1. [DT architecture](/dt/architecture) — layers and domain terms
2. [DT project layout](/dt/project-layout)
3. [DT startup flow](/dt/startup-flow)
4. [DT network and mapping](/dt/network-and-mapping)
5. [DT POI and panels](/dt/poi-and-panels)

## Cross-links

* [Molca Core](/core/runtime-manager) — shared runtime concepts
* [HTTP client](/core/http-client) — if DT shares `HttpClient` / request assets
* [Architecture](/overview/architecture) — product-neutral Core map
* [VR architecture](/vr/architecture) — contrast: training scenarios (not used by typical DT flows)
