Pro-Tip for CAD Designers & Engineers: 📏
A single ambiguous dimension can kill a perfect design. I’ve put together a short video decoding the General Principles of Dimensioning (ISO 129) to help you eliminate manufacturing errors at the source.
Quick highlights:
Difference between functional and non-functional dimensions.
Proper placement for maximum legibility.
Standardized symbols for geometric features.

“When Things Break — What Goes Wrong Before You See the Crack”
“In a recent engagement I reviewed a component that repeatedly cracked under low cyclic loading. The culprit? A combination of insufficient fillet radius + unexpected thermal stress. By re-modelling the geometry in ANSYS and adjusting the radius by 15 % we reduced peak stress by ~20 %.
If your component is giving you grief, sometimes the fix is in the geometry + boundary conditions, not just material swap.
Comment below your toughest failure issue or send me a message — perhaps I can help.
