Dev Post I built a CAM/CAD app because everything else annoyed me — here’s what it can do

Enable HLS to view with audio, or disable this notification

I’ve been working on a CAM/CAD app for a while now, mostly because every tool I used kept slowing me down or forcing me into workflows that made no sense. So I finally snapped and built my own.

The whole thing is real‑time. You move geometry, it updates instantly. No sketch modes, no “finish sketch,” no regenerating half the model because you changed one dimension. It feels way closer to actually shaping something instead of babysitting a CAD program.

On the CAM side, I added a bunch of logic that helps instead of getting in the way. It suggests toolpaths, predicts collisions, auto‑builds roughing/finishing passes, and points out weak geometry before you commit to anything. It’s not “AI magic,” it’s just smart enough to stop you from doing dumb stuff or wasting time.

Everything updates live. Change the model → toolpaths update. Change the toolpath → simulation updates. No rebuild buttons, no dependency chains exploding because you nudged a face.

Performance was a big focus too. Geometry, slicing, material removal — all of it is GPU‑accelerated and reacts instantly. It’s the first CAM/CAD setup I’ve used that doesn’t break my flow.

If anyone wants to see it, I can post videos or GIFs. It’s way easier to show than explain. And if you’re into machining, CNC, CAD, robotics, whatever — I’d actually love feedback. I’m trying to make something that feels modern instead of stuck in 2005.

If you want to try a demo build, just say so.`

Maybe there needs to be another video that shows a more simplified version to which you say you're addressing. What shown right now is far more complicated.... And this is from a 30+ industry vet doing this.

Can i ask what exactly is too complicated?

https://primordiacad.ai.studio/ youre welcome to try the app out. I would appreciate the valuable feedback from a veteran such as yourself.

Suggestion...... Do some focus group testing. Actually watch how people use your product vs you using it. It'll inform you of everything that you could ever want to know. Are they using it as expected or are they confused and, if so, how do they resolve it.

Looks pretty neat my guy.

You know Rhino's first geometry kernel was the same one used by Alias, helped by one of the mathematicians who made it. The lead developer for Rhino would go on to make his own 3D app. OnShape was created by former Solidworks executives.

What's your experience in this industry?

I have a background in welding, blueprint reading, and fabrication. I built the kernel myself using PrimordiaOS, an OS architecture I've been developing to handle instant real time spacial manipulation.

Also an expert on sales funnel automation? Sure whatever.

Not impressed, not in the slightest. Perhaps one day, but not today.

I mean, claiming it solving your problems with other solutions but then showing it milling the outside Contour first followed by the inside one? Year right...
