# ToolChecker
\
**ToolChecker** is a built-in visualization tool that helps ensure your fasteners can be assembled or disassembled using real tools. It simulates tool reach, access, and movement around your selected components.
This feature works **only with QuickInsert-generated components**.
***
### π§ Opening ToolChecker
1. In the **QuickInsert tab**, click the **ToolChecker** button
2. The **ToolChecker form** will open with 14 available tools and 2 hand models to choose from
***
### π Tool Snapping to Selected Component
When you select a **QuickInsert component** (like a bolt, nut, or washer):
* ToolChecker automatically detects the appropriate tool and **snaps** it to the correct position and size
* Example: Selecting a hex bolt auto-snaps a **wrench** or **torque wrench** to the correct size and face
Tool Snapping to Selected Component
> Only QuickInsert components are supported β snapping wonβt work on manually inserted or third-party parts.
***
### π Tool Types & Tool Points
Each tool (e.g., Allen key, wrench, socket) can have multiple **snap points** (e.g., long and short ends):
* You can manually switch between these snap points using a dropdown or button in the form
* For example, an Allen key can be snapped using the short or long side

### π Tool Size & Refresh
Once a tool snaps to a component, the correct size will be selected automatically.
* You can **manually change tool size** via the size dropdown
* If the component changes or needs resyncing, click the **Refresh** button next to the size list
* This resets the tool size and position based on the current component
***
### β» Rotate Tool
You can visualize tool rotation to check for collisions and space:
* Use the **rotation slider** to rotate the tool manually
* Or enable the **Auto-Rotation Animation**, which will spin the tool at a selected speed
* Choose from **3 rotation speeds** (slow, medium, fast)

### π¦ Tool + Component Movement
ToolChecker also lets you simulate movement along the **insertion/removal direction** β perfect for checking if tools can fit in tight spaces during actual assembly/disassembly.
* Use the **Move slider** to shift both the tool and component together
* Use the **Auto-Move checkbox** to move everything by the **length of the selected component**
* Example: If a bolt is 20mm long, the tool and bolt will move out 20mm automatically
* Use the **Refresh button** next to the slider to re-calculate move distance based on the current component
> Nuts and similar components **do not move**, only fasteners like bolts will shift.

### π Choosing Between Multiple Tools
Some components support **multiple compatible tools** (e.g., a hex bolt can use a wrench or torque wrench):
* ToolChecker allows you to select the preferred tool using a **tool selection dropdown** or button list
* The snapping and size logic will adjust based on your selection
***
### β Summary
ToolChecker gives you full control and visual feedback to:
* Snap tools accurately to QuickInsert components
* Rotate and animate tools for clearance checking
* Simulate tool and component movement for real-world disassembly planning
* Choose from multiple tool types with correct orientation and size
