Abstract: With the increasing competition in the automotive industry, the development of new models focusing on quality improvement, cost reduction and delivery acceleration is being optimized. To further enhance the visual perception quality, this paper conducts research on the automotive dimensional refinement technology, establishes relevant processes, and clarifies the focal points of each stage for sub-models. The primary focus is on explaining the evaluation methods for refinement technology during the design stage. These methods involve standardizing evaluation perspectives and dimensions, leveraging software tools like CATIA and VRED for digital modeling and rendering analysis, and utilizing wearable devices for virtual reality simulations. Furthermore, the article summarizes seam division strategies and details specific methods for enhancing delicacy from three dimensions: visual gap, visual surface difference, and appearance R angle.
