When you encounter the following problems, you can use this function.
1. When drawing the entities, due to too many and complicated elements, you need to hide the elements that don't need to be referenced temporarily, in order to improve drawing efficiency.
2. You want to directly display the name of the element in the drawing area to make it easy to check.
Step 1: click View > Entity Display Setting to open Element Entity Display Settings window.
Step 2: Click the check box in front of the element type to add or remove "v" to control whether to display the entity and name of the element or not in the current layer. Click OK to finish the operation.
1. During the drawing process, pressing shortcut key can quickly hide or display the entity or name of an element. There is a default shortcut key for each element, e.g. D is the shortcut key for Door.
