Tools

1: Draw.io diagram/drawing template generator

Generates a Draw.io template that broadly follows the BS EN ISO 5457:1999 standard for technical product documentation.

To generate a template, fill in the form below and click the “Generate Template” button. Note that the template is generated in the Draw.io XML format, with all non-text elements locked.

2: Drawing/PDF diff tool

Generates a visual comparison between the first pages of any two PDF documents. This tool generates the diff by:

1. Extracting the first page from each document and converting it to a raster image.
2. Desaturating each image to yield a grayscale version.
3. Using screen blending modes to apply a blue screen (#0000FF) to the original image and an orange screen (#F28522) to the revision image.
4. Overlaying the revised image with the original image at partial opacity.
