This invention relates to the field of 3D model generation technology, and discloses a sketch-based 3D model generation
system and its operation method. The
system includes: a
computer module, a central
processing module, a sketch import module, a sketch extraction module, a sketch feature capture module, a specification information construction module, a component generation module, a component recognition module, a component
assembly module, a shape generation module, a shape
information acquisition module, a 3D model output module, and a 3D
shape display module. The
computer module is equipped with the central
processing module, sketch import module, sketch extraction module, sketch feature capture module, specification information construction module, component generation module, component recognition module, component
assembly module, shape generation module, shape
information acquisition module, 3D model output module, and 3D
shape display module. This
system can effectively liberate labor, avoid omissions and errors, reduce costs and save time, improve operational efficiency, and facilitate viewing.
