Question：After hiding the model and pressing shortcut key 2, the clothing disappears. What is the reason?

Reason：It may be because an unsewn pattern has flown off to a very distant location.

Answer: You can right-click in the 2D interface and select 'Unsewnpattern' to individually select the unsewn pattern. Press 'F' to focus on them, reset the 2D position, and place them one by one. When the model is hidden, the shortcut for changing the view angle will affect the view of all boards. It is recommended to display the model and rearrange all the patterns. During production, freeze or deactivate any patterns that are not needed.
