Everyone's habit is different, haha, my habit is like this: 1, open a new file first; 2. Press the PL shortcut key and enter a larger number (depending on the scope of drawing); 3. Under normal circumstances, the straight line will exceed the intuitive interface, and no matter how it is reduced, just press Z+ space and A+ space 4 to save it as a file; 5. And mark the size. 6. Arrange the space according to the planned ideas (you should know how you need to feel about the house before doing this). 7. Draw the top floor plan (mainly ceiling, ventilation equipment, lighting, etc. ) according to the plane layout. 8. Draw the elevation. 9. Draw the detailed plan and section structure 10, and draw the construction drawing description 1 1
