# Cleaning and parameterizing CAD feature trees

Refactor parametric 3D models and standardize design history trees using conversational commands

Opens BotBento. Paste the prompt into a bot; nothing is preconfigured.

- When you askSubmit CAD refactoring request
- ThenAnalyze feature tree structure
- ResultReview staged model updates

Review 3D design histories to standardize names, consolidate duplicate operations, and convert hardcoded dimensions into parametric variables. The bot analyzes part geometry and tree structures to prepare clean, maintainable engineering models for production and collaboration.

## Prompt to start with

BotBentoRecommended

```
When an engineer requests changes to a CAD model or feature tree, inspect the existing operation sequence and sketch parameters. Propose clean descriptive names, suggest consolidating redundant extrusions or cuts, and identify fixed values that should become shared parametric variables. Always show a clear diff of proposed tree changes and wait for user approval before applying modifications or deleting any features.
