Hestus is an AI-driven CAD software that accelerates hardware development. It can understand the design intent to predict operations, complete sketch drawing with one click, and has native integration without cumbersome prompts. It provides constraint recommendations, such as connecting dangling points, applying various constraints, etc. It also has functions such as symmetry, mirroring, and arranging graphics, such as generating centerlines, mirroring geometric figures, arranging circular features, etc. It can automatically detect the axis of symmetry for chained mirroring and improve the dangling point function, which can be automatically connected to help engineers clearly express their design intent.
