There is no dimensional tolerance on the paper. What should I do?

There is also a national standard: GB/T 1804-2000 "Tolerance of Linear and Angular Dimensions Without Tolerance", but the drawings should indicate that "Tolerance without tolerance conforms to GB/T 1804-2000" and so on. Pay attention to this problem in the future. /down/download.asp？ Id = 695/read-htm-tid-528381.html/soft/sort024/sort052/521923.html = = = = = That's not easy. I wonder how big the difference is. After all, you didn't make it clear. Unless others are too outrageous, according to the limit deviation value of linear dimension within the range of 6~30mm, the roughest error can reach1mm. If even this is exceeded, it can definitely be said that it is his problem. Personally, I think that since 7mm is marked, the error should be within 0.5mm, which is more in line with the intuitive understanding of ordinary people, and this is also the approximate tolerance in the standard. General tolerance, tolerance-free linear and angular dimensional tolerance shall be implemented according to the following standards (GB/T 1804-2000). The limit deviation value of linear dimension in table 1 is millimeter tolerance level. Basic size segmentation > 6 ~ 30 accuracy F 0. 1 medium m 0.2 coarse c 0.5 coarsest V 1.
