Gear Blank Script Generator

When to use this CAD script generator

• Use it when you need a readable starter script for learning or drafting a simple open-CAD workflow.
• Use it when you want FreeCAD Python, CadQuery, or OpenSCAD text that can be reviewed before entering CAD software.
• Use it for early teaching, documentation, design exploration, and workflow support rather than final manufacturing approval.
• Use it when browser-local processing and no CAD execution are required.

How to use

1. Enter only the small dimensions, pattern counts, script target, and notes needed for the script template.
2. Review the browser-local privacy notice before generating any FreeCAD, CadQuery, or OpenSCAD text.
3. Click the exact generation button; default values, typed edits, URL values, and worked examples do not generate final script output automatically.
4. Review warnings, generated script text, preview visual, assumptions, limitations, downloads, and official documentation before using the script in CAD software.

Input guide

Script target

FreeCAD Python, CadQuery, or OpenSCAD text output.

Blank geometry

Outer diameter, bore diameter, and thickness.

Hub

Optional hub diameter and hub length checked against bore and outer diameter.

Keyway

Optional keyway note with width and depth validation.

Notation

Output interpretation

• The output is gear blank script text, geometry summary, hub/keyway summary, modeling-step explanation, warnings, visual preview, copy action, and downloads.
• Warnings identify review items that must be checked in the target CAD environment.
• Downloads contain the currently generated output only and disappear when inputs become stale.

Supported use cases

• Small browser-local CAD script templates with typed dimensions.
• Educational FreeCAD Python, CadQuery, and OpenSCAD starter workflows.
• Plain text previews, copy actions, and safe script or Markdown downloads after explicit generation.
• Simple primitives, cutout comments, hole layouts, and documented construction notes.

Unsupported patterns

• CAD execution, Python execution, OpenSCAD execution, CadQuery execution, server-side geometry, CAD kernels, and rendered model validation.
• File uploads, STEP/STL/DXF/DWG parsing, native CAD conversion, CAM output, G-code generation, AI design assistance, databases, analytics, tracking, authentication, and payments.
• Final engineering approval, manufacturability certification, standards compliance, or replacement of official software documentation.

Generated script interpretation

• Treat the script as editable starter text, not as a verified CAD model.
• Review part names, units, dimensions, feature order, cutout placement, and export lines before using output in CAD software.
• Check official FreeCAD, CadQuery, or OpenSCAD documentation for version-specific syntax and modeling behavior.

CAD script generation guidance

• Keep the first generated script small and verify one feature at a time in the target CAD software.
• Use the generated parameter block as documentation for design intent.
• Add tolerances, material notes, manufacturing constraints, and drawing details outside this text generator.

Worked examples

Assumptions

• Dimensions are emitted exactly as entered with a visible unit note; no hidden unit conversion is performed.
• Generated scripts are editable starter templates for a human-controlled CAD environment.
• Simple primitives, booleans, hole layouts, and comments are used instead of a geometry validation engine.

Practical guidance

• Use simple part names with letters, numbers, and underscores.
• Keep notes short and avoid pasting detailed proprietary model information.
• After generation, copy the script into a controlled CAD environment and review every generated line.

Common mistakes

• Treating generated script text as proof that the CAD model will rebuild in a specific FreeCAD, CadQuery, or OpenSCAD installation.
• Mixing millimeters, centimeters, meters, and inches without a project-wide unit convention.
• Leaving starter comments, simplified cutout positions, or construction notes unchanged in a production model.
• Using generated geometry for manufacturing without drawing review, tolerance checks, material checks, and fit checks.
• Expecting ScholarTool to execute, render, validate, or repair the CAD script.

Limitations

• ScholarTool does not run FreeCAD, CadQuery, OpenSCAD, Python, CAD kernels, shell commands, or generated scripts.
• The tool does not validate solids, export STEP/STL files, check manufacturability, or verify version-specific syntax.
• Critical geometry, tolerances, standards, materials, and safety decisions require official software documentation and professional engineering review.
