A STEP BY STEP APPROACH

Launch AutoCAD Application

1. Create your first column using Rectangle Command.

Command: REC RECTANG (ENTER)
Specify first corner point or [Chamfer/Elevation/Fillet/Thickness/Width]: 0,0 (ENTER)
Specify other corner point or [Area/Dimensions/Rotation]: @300,300 (ENTER)

Command: Z ZOOM (ENTER)
Specify corner of window, enter a scale factor (nX or nXP), or [All/Center/Dynamic/Extents/Previous/Scale/Window/Object] : E (ENTER)

2. Multiply the column.

Command: AR ARRAY 1 found (ENTER) Enter array type [Rectangular/PAth/POlar] : R (ENTER)

Type = Rectangular Associative = Yes
Select grip to edit array or [ASsociative/Base point/COUnt/Spacing/COLumns/Rows/Levels/eXit]: COL (ENTER)
Enter the number of columns or [Expression] <4>: 4 (ENTER)
Specify the distance between columns or [Total/Expression] <450.0000>: 8000 (ENTER)
Select grip to edit array or [ASsociative/Base point/COUnt/Spacing/COLumns/Rows/Levels/eXit]: R (ENTER)
Enter the number of rows or [Expression] <3>: 2 (ENTER)
Specify the distance between rows or [Total/Expression] <450.0000>: 7000 (ENTER)
Specify the incrementing elevation between rows or [Expresson] <0.0000>: (ENTER)
Select grip to edit array or [ASsociative/Base point/COUnt/Spacing/COLumns/Rows/Levels/eXit]: X (ENTER)

Command: Z ZOOM (ENTER)
Specify corner of window, enter a scale factor (nX or nXP), or [All/Center/Dynamic/Extents/Previous/Scale/Window/Object] : E (ENTER)

3. Create Exterior Wall

Command: ML MLINE (ENTER)
Current settings: Justification = Zero, Scale = 150.00, Style = STANDARD
Specify start point or [Justification/Scale/STyle]: S (ENTER)

Enter mline scale <150.00>: 150 (ENTER)

Current settings: Justification = Zero, Scale = 150.00, Style = STANDARD
Specify start point or [Justification/Scale/STyle]: J (ENTER)

Enter justification type [Top/Zero/Bottom] : Z (ENTER)

Current settings: Justification = Zero, Scale = 150.00, Style = STANDARD
Specify start point or [Justification/Scale/STyle]:

Command: MLINE (ENTER)

Current settings: Justification = Zero, Scale = 150.00, Style = STANDARD
Specify start point or [Justification/Scale/STyle]:

Command: Z ZOOM (ENTER)
Specify corner of window, enter a scale factor (nX or nXP), or
[All/Center/Dynamic/Extents/Previous/Scale/Window/Object] : E (ENTER)
Command: Specify opposite corner or [Fence/WPolygon/CPolygon]:

4. Create Doors and Windows

It’s preferable if you already have a library of blocks. However, if you do not have this library, let us begin the process of building one.

Door: 1000mm(W) x 40mm thickness
Window: 1200mm(W)

After you’ve created the blocks for the doors and windows, copy, paste, mirror, rotate and move it to complete the plan. After you’ve finished the layout, double-click the window to alter the blocks. Add detail to the blocks, and most significantly, add wipeout to the window openings, then repeat the process for door blocks.

Then, change the wipeout frame settings to “0” to see the opening.

Command: WIPEOUTFRAME (ENTER)
Enter new value for WIPEOUTFRAME <1>: 0 (ENTER)

5. Create interior wall

Since layout is typical just copy the exterior wall to inner wall location, and then change the Mline scale in the object properties dialog.

Congratulation you Have made your classroom layout plan!!!
