A post from our Founder & CEO Nathan.
CAD lies to you. Not intentionally or maliciously, but it does lie.
A 3D model looks finished and real... it has shadow, reflection, you can spin it, zoom in, show it to your board and investors, and they’ll likely nod and say, “yes, that looks about right.”
But a screen can’t tell you the button is in exactly the wrong place for a thumb. It won’t show you the assembly sequence is going to be a nightmare. It can’t tell you the grip feels wrong, or the lid flexes when it shouldn’t, or the whole thing is three millimetres too wide to fit the case it needs to ship in.
Those things only reveal themselves when something exists in the real world.
I’ve been doing this long enough to know that the moment someone holds a physical prototype for the first time, the conversation changes completely, every time and without exception.
Things they were certain about on screen suddenly feel wrong. Things they were worried about turn out to be fine. The product gets better in that moment more than it did in weeks of revision cycles.
That’s not a failure of the design process. That’s the design process working.
Get something into your hands, early, often and absolutely before you’re certain it’s ready.
The best decisions in product development aren’t made at a screen. They’re made when someone picks something up, turns it over, and says - ‘yeah, that’s not quite right’.
Trust that moment - it’s worth more than any render.
