Agree with the other commenter, this definitely needs more details to describe the nature of the breakthrough. Sophisticated CAD in the browser is not a new thing. For example, Onshape is a CAD application meant for design and manufacturing of rather sophisticated products, and the user portion runs in the browser.
The problem in CAD space isn't the tooling or design capabilities - it's the data model.
It is a freaking nightmare trying to unwind interlinked assets, class libraries, custom components, manually entered specs and annotations, and convert it into something resembling a database (of any variety, we went with a graph DB because it offered more flexibility ...)
AVEVA has a lot of the pieces for this, but they've never put it together into a compelling product.
Ripe for disruption, especially with ML-assisted design.
Let me describe my interpretation of the program. You are presented with a "marble" cube which lets you chisel the shape you want. The problem I see with this application is that you can't even do something as basic as set the depth of the cuts you're taking. It's just removing everything in a straight line based on the camera angle.
Unfortunately, it's just free-hand sketches plus boolean "and" operations. I don't see the breakthrough.
It seems you can use the cutting tool to also 'lock' volumes of the model, which could then be used to set the depth of a perpendicular cut. Not very precise though
I’m a bit hesitant to post a “what about X?” so read this knowing that I’m fully in support of new open source CAD projects.
It seems to me there are no options for open source CAM, is this something you’re interested in? I can use a variety of CAD but when it comes to producing the tool paths and G code, I have to import into something like F360 which is unfortunate.
