At present,the field of new energy vehicles is developing at a high speed.In order to capture the market,the automobile factories require suppliers to reduce the cost by compressing the cycle from design,manufacture to installation and debugging,therefore,the efficient design method is particularly important.Automobile painting project design process generally includes more than ten professional,often crossprofessional design,collaborative design.By using advanced BIM technology,about 90% of the collision interference problem can been eliminated in the design stage,so as to reduce cost,shorten design cycle and improve the competitiveness of enterprises.
