1, open CAD, create a new file, and draw the room type that needs ceiling in the drawing area.

2. Open the original top plan, analyze the position and height of the quantity, and get the scheme of ceiling modeling.

3. Draw the model of the guest restaurant first. The guest dining room in the house is the key, plasterboard ceiling.

4. Gypsum board ceiling in the corridor in the drawing.

5. Next, draw the integrated ceiling of the bathroom and kitchen.

7. Up to now, the ceiling of every space has been drawn. Finally, make a copy of the smallpox map and mark the size of each place.

8. Using linearity, we will mark the drawn figure, so that our elevation will be drawn.

The ceiling width with light band is 350, and that without light band is 300. Press and hold the O key space, enter 350, and all four lines will be offset inward.

Connect the four sides with the F key, and the thickness of the connection represents the width of the ceiling.

When drawing the light band, hold down the O key space, enter the value 100, move the light band to the ceiling 100, change the color of the light band, and mark the value.

1 is divided linearly. For example, the hidden light bands are indicated by dotted lines, and others are indicated by various thick and thin lines. Grasp the principle of thick main line and thin auxiliary line.

Make the elevation clear, don't mark it wrong. The altitude is measured in meters. The outline of the drawing shall be marked with modeling dimensions in millimeters.

Clear marking of lamps and lanterns; 4. Appropriate addition of text marking can clarify the purpose of your drawings.
