CAD structural part lightweight conversion and online browsing method and system

The invention relates to a CAD structural part lightweight conversion and online browsing method and system. The method comprises the steps that S1, a user submits a conversion request of a three-dimensional CAD model through an application system, and a lightweight model conversion queue receives the conversion request, creates a conversion task, releases the conversion task, monitors the state of the conversion task and carries out abnormal state processing; s2, the lightweight model conversion tool obtains a conversion task from the lightweight model conversion queue, and after the conversion task is executed, the task state is updated; and S3, performing dynamic calculation according to the spatial position matrix of the part, performing real-time rendering and loading, and performing display according to user requirements through a lightweight browsing component. According to the method provided by the invention, the model conversion process and lightweight display thoroughly get rid of the constraint of
