Ever wondered why tool handles, barbells, and press-fit parts have that textured pattern on them?
It’s called knurling — and it’s more than just decoration.
In this video, we break down:
• What knurling is
• Common knurl patterns and applications
• How knurling is called out on engineering drawings

For years, we've been building our GD&T resources the old fashioned way...manually, from scratch, one chart at a time.
But looking around LinkedIn, it's clear we've fallen behind. Everyone else has been using AI to create their GD&T content.
We didn't want to be the last ones to jump on the bandwagon, so we did too.

If composite profile has ever sparked a debate between engineering and inspection, this one’s for you:
In this Question Line video, Jason explains composite profile interpretation, taking a closer look at how to understand the lower frame. Using a real drawing example, he walks through the composite profile callout, drawing considerations, and inspection implications.

Knowing a little GD&T might be more dangerous than knowing none at all.

The Dunning-Kruger effect is dangerous in technical fields. Just enough knowledge to feel confident. Not enough to see what you're missing. And no idea that the gap even exists.

GD&T is a perfect example. Partial understanding can feel like complete understanding...right up until production reality disagrees with you. Loudly and expensively.

Not knowing what you don't know is fine, until it isn't. The question isn't whether the gap exists. It's whether you find it before production does.

If you’re trying to control the alignment of the ID and OD on a cylindrical part, which GD&T control is the better choice—Position or Concentricity?

In this Question Line video, Jason walks through several form error scenarios to compare position and ASME concentricity measurements and explains the best approach based on the part’s intended function.

The fastest way to make better drawings is to watch someone try to make your parts.
When's the last time engineering visited the shop floor? Be honest.
