Core Viewpoint - The event at Harbin Engineering University involved over 1,200 students and faculty members creating a giant snow sculpture of the "Fujian" aircraft carrier and three carrier-based aircraft, showcasing teamwork and engineering skills [1][3]. Group 1: Event Details - The snow sculpture project took place on December 28, with participants working for about one and a half hours to complete the 230 meters long and 112 meters wide design [1][3]. - The project was characterized by a collaborative effort, with sounds of shovels and brooms creating a lively atmosphere during the construction [1][3]. Group 2: Design and Technology - The design process began in September and involved over 60 iterations, utilizing a top-down three-dimensional composition to enhance visual impact [3]. - The final design included more than 1,300 feature points, representing a significant advancement in both visual representation and engineering practice [3]. - The CAD drawing team played a crucial role in extracting key contours and setting positioning coordinates for the construction, ensuring precision in the final output [3][5]. Group 3: Precision and Technology Utilization - The project employed Beidou satellite positioning technology to achieve centimeter-level accuracy in placing over 1,300 feature points on the construction site [5]. - Teams were organized into ten groups, each led by a graduate student, to accurately mark the designated points using real-time differential positioning technology [5].

Group 1 - The event involved over 1,200 students and faculty at Harbin Engineering University creating a snow drawing of the "Fujian" aircraft carrier, showcasing a blend of art and technology [2][4] - The drawing utilized advanced technology, specifically the Beidou satellite positioning system, achieving centimeter-level accuracy for the placement of over 1,300 coordinate points [4] - The scale of the event has grown significantly since its inception in 2018, expanding from around 100 participants to over 1,200, and evolving from simple outlines to a multidisciplinary approach with advanced technical support [5] Group 2 - The event was live-streamed online, attracting positive feedback from viewers who appreciated the creativity and execution of the project [5] - The "Fujian" aircraft carrier's commissioning marks China's entry into the "three-carrier era," instilling pride among participants who contributed to the snow drawing [5]
