Question:

I follow the door/window identification procedure to identify them, but nothing is identified.

Solution:

When identifying door/window, identify the door/window schedule first, and then prick wall sideline.

In 2D drawings, there is no height information on door/window openings, so the door/window openings cannot be identified correctly by identifying them directly. To identify door/window openings correctly, you need to identify the door/window schedule first to complete their attribute info, and then follow the door/window identification procedure to identify them.
