- [Import GTC package](https://support.toolingmetrics.com/en/library/tutorials/import-gtc-package.md): Bulk-import a cutting tool manufacturer's product catalog into Tooling Metrics from a GTC package file.
- [Create custom product](https://support.toolingmetrics.com/en/library/tutorials/create-custom-product.md): Add a single product to Tooling Metrics from individual asset files when no GTC package is available.
- [Build your first tool assembly](https://support.toolingmetrics.com/en/library/tutorials/build-tool-assembly.md): Combine products into a complete tool assembly in Tooling Metrics, with a 3D model, drawing, and bill of materials.
- [Calculate cutting data](https://support.toolingmetrics.com/en/library/tutorials/calculate-cutting-data.md): Use the Tooling Metrics machining calculator to define cutting parameters and estimate machining results for an operation and workpiece material.

This series is for the **Tooling Engineer or CNC Programmer**, who keeps the tool library and builds the tool assemblies the shop uses. It takes about 45 minutes.

**Before you start:** finish the [Administration](https://support.toolingmetrics.com/en/admin/tutorials/) series. Following the [Quickstart](https://support.toolingmetrics.com/en/start-here/quickstart/library/) demo instead of your own data? Use its product list and tool assembly table.

**After this series:** the CNC Programmer starts the [Engineering](https://support.toolingmetrics.com/en/engineering/tutorials/) series.
