Tutorial - Floor Plan

Aims and Objectives

To help you gain an appreciation of applying AutoCAD commands in engineering drawing production, you will create a floor plan by using multilines. See Figure 1. In making this drawing, you will use multiple, polyline, trace, donut, and 2D solid object.:

Multiple Lines

Multiple lines are sets of parallel lines. They are very useful in 2D architechural or interior design drawings. By using the MLINE command, you may create up to 16 parallel lines at the same time. The style of the multiple lines is set by the MLSTYLE command. To edit a multiple line, you may use MLEDIT command,

From the format pull-down menu, select the Multiline Style... item to use the MLSTYLE command to set up four multiline Style. See Figure <Menu <Browser> <Format>    <Multiline Style....>

Command: MLSTYLE

Next to the item Name:, key in 120WALL. Description is Internal Wall. Select  the [Add] Button to create a new style.

Regions

A region is a special kind of entire. It is defined from a 2D closed area. You may create a closed area using a combination of lines, arcs, polylines, planar 3D polylines, circles, arcs, ellipse, elliptical arcs, and splines. The entires that form a closed area must not intersect each other. With two or more regions, you can combine them together by joining (use the UNION command), cutting (use the SUBTRACT command), or intersecting (use the INTERSECT command).

Figure 18 shows three wash room facilities for the floor plan. You will create them as 2D regions in the chapter and insert them as blocks to the floor plan.

Figure 18 : Wash room facilities

Rectangle

First you will draw a rectangle. A rectangle is a closed rectangular polyline. From the Draw pull-down menu, select the Rectangle item to use the RECTANG command. Set the fillet radius and chamfer distance of the four corners to zero.

<Menu Browser> <Draw>  <Rectangle>
Command: RECTANG
Specify first corner point or [Chamfer/Elevation/Fillet/Thickness/Width]: F
Fillet radius for rectangles <0.0000>: 0
Specify first corner point or [Chamfer/Elevation/Fillet/Thickness/Width]: C
Specify first chamfer distance for rectangles <0.0000>: 0
Specify second chamfer distance for rectangles <0.0000>: [Enter]
Specify first corner point or [Chamfer/Elevation/Fillet/Thickness/Width]: 600,4100
Specify second point: @600,1200

After making a rectangle, select the 2 Points item from the Circle cascading menu of the Draw menu to create a circle. See Figure 19.

<Menu Browser> <Draw>     <Circle>    <2 Points>

Command: Circle
CIRCLE 3P/2P/TTR/<Center point>: 2P
Specify first end point of circle's diameter: MID of [Select A (Figure 19).]
Specify second end point of circle's diameter: [move cursor horizontal to left to display a horizontal tracking line]
type: 4000

Figure 19 : Rectangle and circle created

Use the REGION command to create two regions from the rectangle and the circle. When you form a region from a closed area, you may choose to retain or to delete the original objects. To delete the original object after they are used to form a region, set the DELOBJ system variable to 1.

Command : DELOBJ
New value for DELOBJ : 1

From the Draw pull-down menu, select the Region item to use the REGION command. Because you have set DELOBJ to 1, the original rectangle and circle are deleted after creating the regions.

<Menu Browser> <Draw>     <Region>

Command : REGION
Select object : [Select B and C (Figure 19).]
Select object : [Enter]

Although there is no noticeable visual change in your screen display, the two objects are no more rectangle polyline or circle. They are regions.

Complex Region

As aforementioned, you may combine two or more regions to form a complex region. You can unite, subtract, and intersect regions by using the UNION, SUBTRACT, and INTERSECT commands, repectively. The union of two regions is a complex region whose area contains the area of the first region and that of the second region. The subtraction of two regions is a complex region whose area is found in the first region but not in the second region. The intersection of two regions is a complex region whose area is found in both the first region and the second region.

From the Modify pull-down menu, select the Booleam cascading menu and then the intersect item to use the INTERSECT command to form an intersection of the rectangular and circular regions. See Figure 20.

<Menu Browser> <Modify>     <Solids Editing>    <Intersect>
