Useful CAD Tools & Converters
AutoCAD Utilities for Drafters, Designers, Engineers and CAD professionals
Welcome to my collection of free, easy-to-use CAD tools designed to save time and improve accuracy in your design workflow. As a CAD expert, I’ve created these utilities to solve common challenges that architects, engineers, and designers face daily.
​
Currently available tools:
-
DPI to DPMM Converter – Quickly convert DPI (dots per inch) to DPMM (dots per millimeter) for precise scaling and print accuracy.
-
Hex Color to AutoCAD True Color Converter – Easily transform web hex color codes into AutoCAD-compatible true color values.
-
These tools are lightweight, browser-based, and built to give you fast, accurate results without unnecessary complexity. Whether you’re preparing technical drawings, setting up plotting parameters, or ensuring color accuracy in AutoCAD, these converters are here to streamline your workflow.
I’ll be adding more CAD utilities soon, so check back for updates or bookmark this page.
GitHub also available.
