We recently shared the drawing below on social media and asked our audience to spot all the mistakes. In this video, Jason reviews the same drawing, walking through each error and explaining why it violates the rules of ASME Y14.5.

 

 

For this exercise, only errors that break ASME Y14.5 standards are called out. Design choices, such as datum feature selection or material choice, are left to the designer’s discretion and are not evaluated here. 

 

Before you watch: 

Take a look at the drawing—how many mistakes can you spot before hitting play?
