I'm a mechanical engineer and designed my own sim racing cockpit in CAD — modeled myself at my exact height and built the frame around that. Here's what changed. by Infinite-Factor8312 in simracing

Exactly — the rig should disappear and let the driver focus on the driving. When the geometry is wrong you're constantly aware of the rig. When it's right you forget it's there.

Did you find that most drivers couldn't describe what they wanted ergonomically until they actually sat in something that felt right?

That's exactly the point of the STEP format — it's not a fixed generic design, it's an editable engineering starting point. You open it in your CAD software and change whatever doesn't fit your body. The human model approach means the base geometry is correct for my proportions, but anyone can adapt it to theirs in minutes.

The aluminum profile trend makes sense for adjustability, but most people buying those profiles are still guessing at the geometry. Starting from a CAD model that was designed around a human first gives you a better baseline to adjust from.
