Agentcad can now compare two models to each other visually and quantitatively. This allows your agent to perform more complex cad design work, such as reducing the number of blades from 5 to 7 as in this cadgenbench challenge.
I've been gearing up to submit agentcad to cadbench which is an eval set for CAD models.
As I've been going through that, I've found some error scenarios where everything "looks" right to me and to the agent but is actually off by a small amount here or is missing a specific shape over there.
