★Why are some drawing objects displayed in a layout space but not displayed in the model space

Issue:

Why are there some drawing objects that can be seen in a layout space, but not in the model model space?

Solution:

• Some objects are created in the layout space. Therefore, they can only be seen in the layout space, not in the model space.
  Go to the layout space, and try to select the objects without going into the viewport. 
  If the objects can be selected, then they are created in this layout space.
  
  
  
• Some objects, for example, texts, annotations, and hatches can be annotative.
  
  When the viewport scale in the layout space is the same as the annotative scale of the objects, they will be displayed.
  
  When the model space annotation scale is different from the object annotation scale, and the Annotation visibility is set to the current scale only, then these objects won't be displayed in the model space.
  In this scenario, click on the Annotation Visibility icon in the bottom-right corner, and then ZWCAD will show annotative objects for all scales in the model space.
