AutoCAD draws multiple lines, reference lines and rays

Example 4 Drawing House floor plan

Step 1 Create a new graphics file

Starting the AutoCAD 2002 system and creating a new graphic file with "ACADISO.DWT" as the template;

Step 2 Draw Guides

(1) First use the "xline" command to draw the horizontal reference line. Select the icon on the Draw toolbar and, as prompted, enter the command line:

Command: _xline Specify a point or [Hor/ver/ang/bisect/offset]: H Enter
 	Select the Hor option to draw a horizontal reference line
Specify through: Enter /p>	//Specify the first reference line to pass the point (0,0)
Specify through point:0,400 Enter	//Specify the second reference line through point (0,400)
Specify through point:0,900 Enter	//Specify the third reference line to pass point (0,900)
Specify through Point:ent ER	//press Enter to determine

(2) then use the "xline" command to draw the vertical reference line. Select the icon on the Draw toolbar and, as prompted, enter the command line:

Command: _xline Specify a point or [Hor/ver/ang/bisect/offset]: v Enter
	Select the Ver option to draw a vertical reference line
Specify through point:0,0 Enter	Specifies the first line of reference to pass through the point (0,0)
Specify through point:450,0 Enter	Specifies the second reference line to pass the point (450,0)
Specify through Point:enter	Press the ENTER key to determine

(3) Use the "Ray" command to draw the Rays. Select Menu "Draw (draw)" → "Ray (Ray)" and, as prompted, enter at the command line:

Command: _ray Specify start point:450,600 Enter	Specifies the beginning of the Ray (450,600)
Specify through point:t:950,600 Enter	Specifies the beginning of the Ray (950,600)
Specify through Point:enter	Press the ENTER key to determine

(4) Again using the "Ray" command, specify points (950,400), (950,900) and points (1100,400), (1100,0) and points (700,600), (700,900) and then draw three rays respectively, When finished, the results are shown in Figure 4-9 (the dots in the figure are used to illustrate the subsequent drawing work).
