1 Page 1 Introduction to AutoCAD 2012 Alf Yarwood Chapter 16 Exercise 1 1. Open AutoCAD 2012 with a double-click on its shortcut icon in the Windows desktop. 2. Open the template acadiso.dwt. 3. Construct the required building symbol drawings to a scale of 1: Save each symbol as a block within the drawing. 5. Save the drawing to the file name blocks for all exercises.dwg and close the drawing. 6. Open another acadiso.dwt template. 7. Left-click the DesignCenter icon in the View/Palettes panel and select from its Folder List the drawing blocks for all exercises.dwg. 8. Left-click the cross to the left of the drawing name and left-click again on Blocks. The building symbols appear in the right-hand side of the DesignCenter palette. 9. Working to the scale 1:50, construct an outline of the required building plan using the Polyline tool set to a Width of 1. Make the outer walls from plines 5 units apart and the partitions from plines at 2 units apart. 10. Drag the necessary symbols from the DesignCenter into the drawing. 11. Because the symbols dragged into the drawing area are blocks they may need to be exploded (Explode tool from the Home/Modify panel) and some trimming and stretching may be necessary in order to clear unnecessary details or to change the scale of some symbols - e.g. windows. 12. When completed save your drawing to a memory stick with the file name 16_Exercise01.dwg. 13. Close the drawing window.

Following the same procedures as described for the drawing in answer to Exercise 1, construct the required drawing. The two floor plans below show one possible answer to the exercise. 4. Save your drawing to a memory stick with the file name 16_Exercise02.dwg. 5. Close the drawing window.

Following the same procedures as described for the drawing in answer to Exercise 1, construct the required drawing. The floor plan on the right shows the resulting drawing. 4. Save your drawing to a memory stick with the file name 16_Exercise03.dwg. 5. Close the drawing window. Chapter 16 Exercise 4 The illustrations throughout this and Exercise 5 before rendering are in Visual Style/Conceptual. 1. Open AutoCAD 2012 with a double-click on its shortcut icon in the Windows desktop. 2. Open the template acadiso3d.dwt. 3. Open the Layer Manager palette and make four new layers Blue, Green, Magenta and Red with colours the same as the layer names. 4. Make layer Red current. 5. Assuming the front wall height is m and working to a scale of 1:50 construct the front wall from an extrusion of height Then construct the rear wall. 7. Make layer Blue current and construct the window frames for the front and rear walls and the door for the front wall.

4 Page 4 8. Make layer Magenta current and construct the end walls, followed by making layer Blue current and constructing the end wall windows. 9. Place in the SW Isometric view and make a union of the four walls. 10. Make layer Green current and construct the roof from a pline of the end of the roof which is extruded. 11. Make layer 0 current and construct a floor for the house - an extrusion of height Features such as a paths, guttering can be added if thought fit. Published by Elsevier Ltd. All rights reserved

5 Page Turn off all layers other than Red. 14. Click the arrow at the bottom right-hand corner of the Render/Materials panel to bring the Materials Editor palette on screen. Click button at the bottom right-hand corner of the palette to bring the Materials Browser palette on screen. In the Autodesk Library list click Masonry-Brick. In the Sort list of brick icons which appears select Flemish and when the icon appears in the Different Materials area of the palette, drag the icon on to the wall. 15.

The Texture Editor palette appears. In the Scale filed enter 50 in the Sample Size/Width field, the Height figure automatically changes to retain the balance between width and height. 17. Render the walls model again. The result is shown on page Turn layer Red off. 19. Turn layer Green on. Add the material Roofing/Slate Blue to the roof model using the same procedures as when adding a material to the walls. 20. Turn layer Green off and layer 0 on and add the material Flooring-Carpet/Berber Pattern 3 to the floor. 21. Turn layer 0 off and layer Blue on and apply the material Paint/Paint to the door and windows. 21. With the 3DOrbit tool place the model in a new position. 22. Turn all layer on and render. 23. Change to perspective view and render again. 24. The results of items 21 to 23 are shown on Page 6.
