Abstract
The invention provides a position changing method of a zero-component three-dimensional model and aims to solve the problem that a position changing method of the zero-component three-dimensional model is quite troublesome in operation, less prone to causing errors and the like in the prior art. The position changing method includes adopting CATIA software to build a three-dimensional model of a zero component; before building the zero-component model, establishing a zero-component axis system, creating a structure sketch and an entity model of the zero component in the axis system, and maintaining all data and constraints of the zero-component model to only be related with the zero-component axis system during modeling; if coordinate position of the zero-component three-dimensional model need to be changed, double-clicking and editing the zero-component axis system to establish new coordinate position for the zero-component axis system according to the position needed to be changed, and refreshing. The position changing method has the advantages that when the coordinate position of the zero component needs to be changed, the zero-component model can be quickly changed to the new coordinate position only by modifying and editing the zero-component axis system, and the modeling process of the zero component is fully retained and can be used for reference, so that repeated design is avoided.
