2015 年以前的油田公司科技革新汇报中，零件设备类革新多以照片进行展示，由于拍摄角度等问题，往往不 能够将设备的细节展示清楚，而使用Solidworks 制作的3D模型可以全角度旋转，清晰地展示物体的所有尺寸、细节、轮廓图、 运行方法等，生成的工程图可以作为车间认可的图纸，对设备推广具有很强的辅助性，符合油田公司对于3D模型的展示要求。

In the report of scientific and technological innovation of Daqing Oilfield before 2015, the innovation of spare parts equipment was shown in photos. Due to the shooting angle, photos cannot show the details of the equipment. The 3D model made by Solidworks can be rotated at all angles. And all dimensions, details, contour maps and running methods of objects can be shown clearly. At the same time, the generated engineering drawing can be used as the approved drawing of the workshop, which has a strong support for the promotion of equipment. Thus the 3D model can meet the requirements of Daqing Oilfield for display.
