Hello Shibuya san
Today what time are you free I want to discuss with you about DWG rev process update from Customer to Sale to QA &Engineer dept to update into the file. This is one system that cause to problem when you want to match Engineer DWG with Customer DWG. Normally we should check internal between sale and engineer. And every customer have this problem. And depends on our sale that get DWG update and share to QA & Engineer?
