DXF Generator

Convert a photo of your tool drawer into precise CNC-ready vector files.

1. Quick Start Guide: From Photo to DXF Cut File

This application converts a single photograph of tools in a drawer/tray into a ready-to-use DXF file for CNC cutting foam inserts.

  1. Preparation: Place your tools in a drawer and include a reference coin (assumed to be 0.955 inches / 24.25mm wide, e.g., a US Quarter). Ensure clear, even lighting.
  2. Upload: Upload the image.
  3. Configure: Adjust the Offset Value (clearance around the tool) and select options like Finger Clearance and Boundary.
  4. Run: Click the "Submit" button (automatically generated by Gradio).
  5. Download: Review the Outlines and Output Image, then download the final DXF file for your cutting machine.

2. Expected Inputs

Image Requirements

  • Reference Object is Mandatory: The system must detect a specific reference object (default: coin roughly 0.955 inches wide) to correctly calculate the real-world scale (inches/pixel).
  • Placement: The image should be taken from directly above the drawer (minimal perspective distortion).
  • Lighting: Clear, shadow-free lighting is crucial for object detection and masking.

Processing Parameters

Parameter Purpose Default Value Guidance for Non-Tech Users
Offset Value The amount of space (clearance) added around the tool profile. This is the buffer to ensure the tool fits easily into the foam cutout. 0.075 Increase this value for thicker tools or if you need looser cutouts.
Offset Unit Specifies whether the offset value is in millimeters or inches. inches Match this to your preferred measurement system.
Add Finger Clearance? Adds a small circular cutout to the side of the tool profile to allow easy removal using a finger. Yes Recommended for most tools.
Add Rectangular Boundary? Defines the exterior rectangular shape of the entire foam insert (the boundary of the drawer). Yes Required if you need a rectangular outer boundary for cutting.
Boundary Length/Width The actual dimensions of the drawer/tray area for the foam insert. 50.0 (in the selected unit) Must be larger than the combined area of all tools plus margins.
Annotation Text to engrave/cut into the foam, typically placed at the top of the boundary box. (Max 20 chars) (Empty) Use this to label the tray (e.g., "Wrench Set").

3. Expected Outputs

Output Field Description Purpose
Output Image The original image overlaid with the detected tool outlines (including offset and finger clearance). Visual confirmation that the detection and sizing are correct relative to the original photo.
Outlines of Objects A clean, scaled, white-background image showing only the outlines (blue lines). This visually represents the final geometry exported to the DXF. Final quality check for shape and spacing before CNC cutting.
DXF file The final vector file containing the tool outlines, boundary box, and text annotation (if included). Ready to upload to CNC machine software (AutoCAD DXF R2000 format).
Mask The binary image used internally to generate the tool contours after applying the offset value. Technical output for debugging segmentation issues.
Scaling Factor The calculated real-world scale (inches per pixel) determined by the reference coin. Confirmation of measurement accuracy. Values close to 0.7 are common for phone photos.
