## Overview - The **Indent Feature** is a modeling tool that reshapes a solid body by pressing the geometry of a second intersecting body into it - It creates precise pockets, deformations, or cuts based on the exact contours of a secondary shape - Requires at least two distinct bodies in the workspace to function ## Key Concepts - **Target Body** – the primary solid body that will be modified or reshaped - **Tool Body** – the secondary body (solid or surface) whose shape drives the indent or cut - **Clearance** – an offset distance added between the tool body and the resulting indented surface to allow tolerance - **Thickness** – the specified wall thickness of the indented geometry when forming a pocket - **Keep Selections** – creates the indent pocket around the region of the tool body that was clicked - **Remove Selections** – inverts the logic, forming the pocket on the opposite side of the clicked tool body region - **Cut Option** – changes the operation from a deformation into a material removal (boolean-style slice) ## Detailed Notes ### Basic Indent Operation - **Prerequisites:** - The workspace must contain at least two distinct bodies - When creating the Tool Body, the **merge result** (boolean add) option must be **unchecked** to keep bodies separate - **Accessing the tool:** - If not on the standard toolbar, it is typically found under the top menu path: **Insert > Features > Indent** - **Selection logic:** - Selecting a **Tool Body Region** defines two things simultaneously: 1. Which body acts as the tool 2. Which side/face of the tool body dictates the resulting shape - **Keep vs. Remove:** - **Keep** – wraps the indent around the face you clicked - **Remove** – applies the indent to the opposite side of the face you clicked - **Direction control:** - A reverse direction toggle determines whether the resulting geometry wraps **larger** than the tool body or offsets **smaller** ### Handling Multiple Tool Bodies - The Indent feature **cannot be directly patterned** - **Correct workflow:** 1. Create a **pattern of the Tool Bodies** first 2. Apply the Indent feature to all patterned tool bodies at once - **Performance optimisation:** - Selecting multiple tool bodies triggers real-time preview generation, which can cause lag - **Select Tool Body regions first**, then select the **Target Body last** so the system only calculates the complex preview once - After completing the feature, **hide the tool bodies** to clearly inspect the resulting indents ### Managing Multiple Tool Regions - When the Target and Tool bodies intersect in complex ways (e.g., passing through a grid of ribs), the software divides the tool into multiple distinct **regions** - **Selective indenting:** click specific regions individually to apply the indent only where needed - **Efficiency shortcut for selecting all regions:** 1. Select the single, unbroken face of the tool body from the **opposite side** (e.g., the top) 2. Switch the setting to **Remove Selections** 3. This inverts the logic, effectively keeping all regions on the other side with a single click ### Surfaces and the Cut Option - **Valid body combinations:** - Solid Target + Solid Tool → **Allowed** - Solid Target + Surface Tool → **Allowed** - Surface Target + Surface Tool → **Not Allowed** (at least one solid body is required) - **Cut option behaviour:** - Changes the operation from deformation to **material removal** - When enabled, the Keep/Remove selections toggle **disappears** - Select a surface as the tool body, then choose which side of the solid target body to cut away - The surface acts as the slicing boundary - **Clearance offsets** can still be applied in Cut mode ## Tables ### Feature Options Reference | Feature Option | Function | Primary Use Case | |---|---|---| | **Keep Selections** | Wraps the indent around the selected face | Standard pocket creation | | **Remove Selections** | Inverts the selection, applying the indent to unselected regions | Quickly selecting many disjointed regions | | **Cut Option** | Uses the tool body to slice and remove material from the target | Trimming a solid using a complex surface | | **Clearance** | Adds a gap between the tool shape and the new target surface | Designing packaging or mating parts requiring tolerance | ### Valid Body Combinations | Target Body | Tool Body | Supported | |---|---|---| | Solid | Solid | Yes | | Solid | Surface | Yes | | Surface | Surface | No | ## Diagrams ### Indent Feature Workflow ```mermaid flowchart TD A[Start Indent Feature] --> B[Ensure two separate bodies exist] B --> C[Select Target Body] C --> D[Select Tool Body Region] D --> E{Choose Selection Mode} E -->|Keep| F[Indent wraps around clicked face] E -->|Remove| G[Indent applied to opposite side] F --> H[Set Thickness and Clearance] G --> H H --> I[Toggle Direction if needed] I --> J[Confirm Feature] J --> K[Hide Tool Body to inspect result] ``` ### Multiple Tool Bodies Workflow ```mermaid flowchart TD A[Need to repeat an indent pattern] --> B[Create Tool Body geometry] B --> C[Pattern the Tool Bodies first] C --> D[Select all Tool Body regions] D --> E[Select Target Body last] E --> F[Apply Indent Feature] F --> G[Hide Tool Bodies] ``` ### Cut Option Decision Flow ```mermaid flowchart TD A[Enable Cut Option] --> B{Tool Body Type?} B -->|Surface| C[Select surface as slicing boundary] B -->|Solid| D[Select solid tool body] C --> E[Choose which side of target to remove] D --> E E --> F[Apply Clearance offset if needed] F --> G[Confirm Cut] ``` ## Key Terms - **Multi-body Part** – a single file containing more than one contiguous solid or surface volume - **Feature Manager / Tree** – the UI panel listing the chronological history of operations and bodies in a part - **Section View** – a temporary visual slice of the model used to inspect internal geometries and clearances - **Boolean Operation** – a set operation (add, subtract, intersect) combining two or more bodies - **Merge Result** – a toggle that, when enabled, automatically combines a new body with an existing one into a single volume - **Patterning** – duplicating a feature or body in a linear or circular array ## Quick Revision - The **Indent feature** reshapes a **Target Body** using the geometry of a **Tool Body** - Always **uncheck "merge results"** when creating the tool body to maintain separate bodies - The Indent feature **cannot be patterned directly** — pattern the tool bodies first, then apply Indent to all at once - **Keep selections** forms the indent around the clicked face; **Remove selections** forms it on the opposite side - To quickly select many intersecting sub-regions, select the opposite face and choose **Remove** - Select **Tool Body regions first** and the **Target Body last** to minimise preview lag - Valid combinations: **Solid + Solid** or **Solid + Surface** — never **Surface + Surface** - The **Cut option** converts the indent into a boolean-style slice that removes material - **Clearance** adds a tolerance gap between the tool shape and the resulting surface - After completing the indent, **hide tool bodies** to clearly view results
