Three-dimensional parameterization rapid modeling method for crane

The invention discloses a crane three-dimensional parameterization rapid modeling method, which belongs to the technical field of mechanical design and manufacture, and comprises the following steps: selecting a crane structure through a visual interface, inputting corresponding specification and model data, displaying a preview graph of the selected crane structure on an interactive interface, and automatically updating the preview graph along with the change of the data. The method comprises the following steps: dynamically reflecting the real structure of a product, calculating input data, calling out corresponding data from a product database, displaying the data in an interface for designers to use, generating a two-dimensional engineering drawing and a three-dimensional model of a selected crane structure, assembling the three-dimensional model according to the type of the selected crane, and displaying the assembled three-dimensional model in the interface. According to the method, an overall three-dim
