The embodiments of the present specification disclose a model splicing method, device, equipment and readable medium. The scheme can include: obtaining a first model and a second model to be spliced; the first model has at least a first boundary corresponding to a second boundary of the second model; moving the first model and the second model, the distance between the first boundary and the second boundary after moving is less than a certain distance, and the first boundary and the second boundary after moving form a splicing surface; the angle between each predetermined shape pattern adjacent to the first model in the splicing surface and the first boundary is a first angle, and the angle between each predetermined shape pattern adjacent to the second model in the splicing surface and the second boundary is a second angle; adjusting the first model and the second model to obtain a spliced model, and the sum of the first angle and the second angle after adjustment is less than the sum of the first angle and the second angle before adjustment.
