The invention relates to the technical field of data processing, in particular to a data storage method and system for CAD drawing data, and the method comprises the steps: obtaining all data points on the CAD drawing data; according to the bifurcation degree of each data point and the continuity degree of each data point, the segmentation degree of each data point is obtained, and then all segment data points and all segments on the CAD drawing data are obtained; obtaining CAD drawing data under a plurality of scales, and obtaining all fitting data points in each segment under each scale according to the fitting degree of each data point in each segment under each scale; obtaining an optimal scale according to the optimal degree of each scale; and carrying out data fitting on all fitting data points in each segment under the optimal scale to obtain a fitting result, and carrying out compression storage on the CAD drawing data. According to the method, it is guaranteed that CAD drawing data are in lossless ch
