I'm curious to know, what exactly is it that you're looking for that would make something better than Rhino? Rhino, as I understand, is a powerful 3D modeling tool widely used in various industries like architecture, product design, and animation. Are you looking for a tool that offers similar capabilities but with additional features or optimizations? Perhaps you're seeking a more intuitive user interface, a broader range of supported file formats, or even a solution that integrates better with your existing workflow. Clarifying your specific needs and requirements would help me provide a more accurate answer to your question.
