2.1 Windows 10: Autosketch

All modern versions of Windows 10 (and 11) are 64-bit by default. Microsoft removed the NTVDM layer completely from 64-bit editions. Therefore, if you try to double-click AUTOSKET.EXE on a standard Windows 10 64-bit PC, you will see:

"This app can’t run on your PC" or "The version of this file is not compatible with the version of Windows you’re running."

The Smart Dimension Assistant modernizes the AutoSketch 2.1 experience without breaking the lightweight, minimalist nature of the software. By reducing the click-count required for basic dimensioning, it brings a taste of modern CAD efficiency to a classic platform.
