In this project, you will do the following:

• Set up the drawing, including Limits, Units, and Layers.

• Use the LINE, PLINE, and BHATCH commands to create objects.

• Use the ARRAY command to create objects from existing objects.

• Use the FILLET and TRIM commands to modify objects.

SET UP THE DRAWINGStep 1: Start the AutoCAD program.

Step 2: To create a new drawing, invoke the NEW command from the Quick Accesstoolbar.

AutoCAD displays the Select Template dialog box. Select acad.dwt as the tem-plate file and choose Open. AutoCAD creates a new drawing. Set the Units,Limits, Snap, and Grid to the values shown in the Settings/Value table.

Step 3: Invoke the LAYER command from the Layer panel. AutoCAD displays theLayer Properties Manager dialog box. Create 10 layers, rename them asshown in the table, and assign appropriate colors and linetypes.

DRAWING THE CONCRETE SLAB, BRICK WALL,AND FRAME WALLStep 4: Set Slab as the current layer. Invoke the PLINE command with a width of

0.125 to draw the concrete perimeter and a width of 0.0 to draw the “break”line, as shown in Figure P9–2. Figure P9–1 shows all the required dimensionsto draw the layout. After you draw the layout, the drawing should look likeFigure P9–2.

Step 5: Set Wall as the current layer. Invoke the PLINE command to draw the bricks.The bottom brick is 2-3/8 00 � 3-1/2 00 and is 3/8 00 above the brick ledge.

Step 6: In order to create the arc that represents the mortar joints, invoke theCIRCLE command with the Three point option. Select the corners of theconcrete and the brick that the desired arc touches, and then drag the cursorto a point that gives you a radius slightly larger than the joint gap. Then,using the TRIM command with the concrete and the brick as the objects totrim to, remove the outer part of the circle, leaving the desired arc. Invokethe MIRROR command to create an arc on the opposite edge of the brick,using the Midpoint Osnap on the bottom line of the brick as the basepointabout which to mirror. The completed drawing should look like Figure P9–3.

Chap t e r 9 • Hat c h i n g and Bounda r i e s 9-3

Step 7: Invoke the ARRAY command to duplicate the bricks and mortar joints andcreate a stack of 10 bricks. Draw a “break” line through the top brick, anduse the TRIM command to trim off any brick extending past the “break”line, as shown in Figure P9–4.

Step 8: Invoke the LINE command to draw the 1/2 00 gypsum board and the 1/2 00

exterior sheathing comprising the frame wall. The 2 � 4 sole plate is 1-1/2 00

thick and is shown by crossed lines. The heavy flashing at the bottom can bedrawn with the PLINE command, with 0.125 width; then use the FILLETcommand to round the corner, as shown in Figure P9–5.

Step 9: Set Hatchboundary as the current layer. Draw copies of the two faces of thebottom brick and the two bottom arcs representing the mortar joint. Set theWall layer to OFF. The layout should look like Figure P9–6.

Step 10: Invoke the ARRAY command to duplicate the faces of the bricks and mortarjoints into a stack of 10 double faces and double arcs. Set the Wall layer toON, and using the “break” line through the top brick, invoke the TRIM com-mand to trim off the brick faces extending past the “break” line. Invoke thePLINE command and trace over the parts of the “break” line between thebrick faces. Set the Wall layer to OFF. The layout should look like Figure P9–7.

Step 11: Set Bricksection as the current layer. Invoke the BHATCH command, andusing the ANSI31 pattern at a scale of 6 and a hatch angle of zero (0), selecta point in the boundary of brick faces and mortar arcs just created. Invoke theLINE command, and draw the necessary lines as shown in Figure P9–8 tocomplete the boundaries for the Sand and Earth hatch patterns.

FIGURE P9–6 Layout of the brick and mortar joint

FIGURE P9–7 Layout of the brick wall with mortar joint



Step 12: Set Concrete as the current layer. Invoke the BHATCH command, and usingthe AR-CONC pattern at a scale of 1/2 and a hatch angle of zero (0), selecta point in the boundary representing the concrete slab.

Step 13: Set Sand as the current layer. Invoke the BHATCH command, and using theAR-SAND pattern at a scale of 1/2 and a hatch angle of zero (0), select a pointin the boundary representing the sand beneath the concrete slab.

Step 14: Set Earth as the current layer. Invoke the BHATCH command, and using theEARTH pattern at a scale of 9 and a hatch angle of 45, select a point in theboundary representing the earth beneath the sand and concrete slab.

Step 15: Set Insulation as the current layer. Invoke the BHATCH command, and usingthe FLEX pattern at a scale of 3 and a hatch angle of 45, select a point in theboundary representing the frame wall between the exterior and interiorsheathings. Set the Hatchboundary layer to OFF. The layout should look likeFigure P9–9.

Step 16: Set Text as the current layer. Invoke the LEADER command, and draw thetext object with the leader lines as shown in Figure P9–10.

Step 17: Set Dimension as the current layer. Draw all the required dimensioning tocomplete the exterior wall section as shown in Figure P9–11.

HINT Using the dimensions in Figure Ex9–6b, draw the front elevation of the house. The mainconcern about being able to draw hatch patterns within the proper boundaries is to makesure the boundaries are closed. Overlapping at the intersections of the segments thatmake up the boundary is acceptable. But AutoCAD will not complete the hatch pattern ifthere is a gap between any of the boundary segments.
