INT 123 EXTRA CREDIT

AN EXAMPLE OF REQUIRED 11” X 17” SUBMISSION:

TOOLS NEEDED FOR COMPLETING SUBMISSION:

• Drawing files: Bessey Your Bessey lab model from previous assignments Temp1117 11’ x 17’ template from course website Ceiling Ceiling components from course website W_north North wall elevation from course website W_south South wall elevation from course website W_east East wall elevation from course website W_west West wall elevation from course website

INSTRUCTIONS FOR COMPLETING SUBMISSION:

The purpose of this assignment is to: • Merge the 4 elevations with the plan • Transform a 2-dimensional plan into a 3-dimensional model • Present two section views, two elevation views, and a perspective view of your choice on a presentation sheet

For this exercise, you will continue with your Bessey.dwg file from scan 3. Remember: To cancel a command, use the ESC key

INSERTING ELEVATIONS WITH UCS

1. Open, Find and select your Bessey.dwg file

2. Layer:

Current layer: A-WALL-FULL Create new layers: CEILING, I-WALL-FULL-E, I-WALL-FULL-N, I-WALL-FULL-S, & I-WALL-FULL-W Freeze all layers except A-GLAZ, A-GLAZ-SILL, A-WALL-FULL, & S-COLS

3. UCS, world

4. OSNAP: Intersection & Endpoint NOTE: In AutoCAD, thickness means “in the Z direction”. When the UCS is in World position (flat on the floor), thickness means height. To avoid confusion, you will change the thickness on the interior walls before changing thickness on the exterior walls.

5. Properties Select the inside walls of the model, including the window sills along the east wall and all lines of the door jambs. Zoom and pan as needed. You may find this step easier if you pick objects in small amounts. (NOTE: You may need to hold down the Shift key to select multiple objects). Change the Thickness from 0’0” to 12’8” (this is intentionally higher than the wall height of 9’10” because the wall continues past the suspended ceiling)

3

Close the Properties box by pushing the X in the upper right corner

6. Freeze all layers except: 0, A-GLAZ, A-GLAZ-SILL, A-WALL- FULL & I-WALL-FULL-E, I-WALL-FULL-N, I-WALL-FULL-S, I- WALL-FULL-W, & S-COLS.

7. Current layer: I-WALL-FULL-N Each elevation available on the course website was created flat on the floor in plan view, parallel to the UCS. Each elevation was then “blocked” with the UCS in world. Therefore, each elevation will insert parallel to the UCS, which you will put on each individual wall. After completing the following instructions to insert the north elevation on the north wall, you will need to repeat these steps to insert the remaining three elevations (east, west, and south). When you insert each elevation into the drawing, you will use the intersection at the lower left corner of the wall. This keeps the elevation lined up with the wall.

8. From the View menu, select 3D Views, NE Isometric

UNDERSTANDING AUTOCAD’S MEASURING SYSTEM

Measuring in AutoCAD is based on the Cartesian coordinate system. This system has 3 axes: horizontal (X), depth (Y), and height (Z). The X and Y axes are on the same drawing plane, which is the default drawing surface in AutoCAD. The Z axis is perpendicular to this surface. When in the plan view, this is called the World Coordinate System. The X axis goes from right to left on the computer screen and the Y axis goes from top to bottom. With this in mind, the Z axis would be coming straight out of your screen toward you. All three axes connect at the origin, or the 0,0,0 point. From that point, you can locate any point in space by entering its X coordinate, Y coordinate, and Z coordinate. In AutoCAD, you would enter this as X, Y, Z (obviously, using numbers in place of the letters). All angles are measured counter‐ clockwise. In AutoCAD, you can only draw on one plane or flat surface at a time ‐ ‐ the XY plane. To draw on a surface other than the floor (i.e., plan view), you need to move the coordinate system to a different plane. This is done with the UCS command. This is a great advantage of AutoCAD over other CAD software applications. 9. Open the AutoCAD software again and Open, Basics.dwg

10. Vports, Single

11. Plan, World (or View, Top)

12. The Coordinates panel may be hidden. To display it, select the

VIEW ribbon and right‐click. Then select Show Panels, Coordinates.

13. Set the user coordinate system to measure in “world” or flat on the floor. View > Coordinates > UCS World Or type UCS, World <‐ 14. Turn the UCS icon off. Ucsicon <‐ Enter an option [ON/OFF/All/Noorigin/ORigin/Properties] : off <‐ 15. Turn the UCS icon back on. Ucsicon <‐ Enter an option [ON/OFF/All/Noorigin/ORigin/Properties] : on <‐ SPEED TIP: By pressing the Enter key or spacebar at a blank command prompt, the last command will repeat. 16. Turn off ALL the tools in the bottom Status bar (right below the command line) EXCEPT OSNAP.

UCS Alters the User Coordinate System

 UCS stands for “User Coordinate System” and is the way to define a unique measuring system.

 This will shift the base point and set the orientation for a new drawing plane.

 The UCS command is used extensively in three-dimensional drawing.

 No matter where the coordinate system is moved, the plan view origin (0,0,0) always remains in the lower left corner of the

plan view drawing plane.

 Options:

New Creates a new location for the UCS

Move Defines a new origin point (0,0,0) relative to the current origin

Orthographic Specifies one of 6 predetermined UCS settings

Prev Steps back (as many as 10 times) to the previous UCS

Restore Sets the UCS to a previously saved UCS

Save Stores the current UCS with a user-specified name

Del Removes a saved UCS

Apply Puts the current UCS in one specified viewport or in all viewports

World Returns the coordinate system to the default plan view

DRAWING ON THE WALLS IN 3D

17. The Views panel may be hidden. To display it, select the VIEW ribbon and right‐click. Then select Show Panels, Views.

18. Change from this perspective view to View 1.

19. Place the model in an isometric view.

From the View ribbon, Views, select NE Isometric.

An isometric view is a three‐dimensional (3D) view that shows the length, width and height of the model (i.e., its XYZ). All sides are equally inclined to the drawing surface in an exact proportion of 1:1:1. The X, Y, and Z axes are 120 degrees apart and all have the same scale. All vertical elements remain vertical and X and Y axes are shown 30 degrees from the horizontal.

20. Find out what layer the walls are on by picking on any pink wall section. Right‐click to access a menu. Select Quick Properties at the bottom. (You can also double‐click on an object to open the Quick Properties box).

In the Properties box that appears, it lists Layer 2 as the layer for the walls. Push the X in the upper corner to close this window. 21. With the wall still highlighted, right‐click to access the same menu.

Select Properties at the bottom. Notice this box is larger and provides more information about the geometry selected. It can also be used to CHANGE the object’s properties, like to change its layer or linetype. We’ll come back to this Properties box later.

UCSicon Controls the display of the User Coordinate System icon

 The measuring system is represented by the ucsicon (the XYZ arrows in the lower left corner of the screen).

 The ucsicon can be turned on (shown) or off (hidden).

 It can be displayed in all viewports or in just the current viewport with the option All.

 The default setting is Noorigin, which puts the UCS icon in the lower left corner of the viewport.

 The size, color, and appearance of the UCS icon can be controlled in the UCS Icon Properties box.

22. Press the Esc key to get rid of any blue grips on your screen.

23. Open the Layer Properties box. Layer <‐ Double‐click on the Status option next to Layer 0 to make it current (if not current already) To freeze all layers except the walls and layer 0, right‐click to access a pop‐up menu. Select “Select All” All layers will highlight. Select any sunshine icon. A warning box will appear. Push Close. The sunshine icons will turn to snowflakes. Pick on the “2” of layer 2 to un‐highlight the selection. Change layer 2’s snowflake icon to a sunshine icon. Close this box You should now see only the walls of the drawing. This is helpful when trying to create new user coordinate systems.

7

Put the Coordinate System on the South Wall 24. Put the User Coordinate System on the south wall (the two door openings). This alters the measuring plane so you can draw

vertically on this surface. If using the ribbon menu, select View, Coordinates, 3‐point.

UCS <‐ Specify origin of UCS or [Face/NAmed/OBject/Previous/View/World/X/Y/Z/ZAxis] : n <‐ Specify origin of new UCS or [ZAxis/3point/OBject/Face/View/X/Y/Z] <0,0,0>: 3p Specify new origin point <0,0,0>: pick the lower left corner of the interior south wall (this is the wall with the 2 openings) Specify point on positive portion of X‐axis <#, #, #>: pick ANY POINT along the south wall baseline Specify point on Y‐portion of the UCS XY plane <#, #, #>: pick the upper left corner of the interior south wall NOTE: The UCS icon will flip up and your crosshairs will also alter. When changing the placement of the coordinate system, always confirm that your crosshairs are aligned in the correct direction. In this case, one crosshair should be at a 45‐degree angle and the other one should be perfectly vertically. If this is not the case, do UCS, 3 point again.

8

25. Place the UCS on the north wall using the 3-point

option learned previously. The north wall is toward the left on your screen.

Confirm that the coordinate system is straight and on the wall before you proceed. Confirm this by looking at the Y-axis of the UCS icon and the Y-axis of the crosshairs. If these are both perfectly vertical, the UCS is correct.

26. Insert <- Pick on the Browse... button Select w_north from the location you saved it (after downloading it from the course website) Push Open

Insertion point: Check box Scale: Uncheck box Rotation: Uncheck box Explode: Check box Push OK When transferred to the command line... INSERT Specify insertion point for block: pick the lower left corner of the north wall using your Osnap The north elevation will appear on the wall. Zoom to the corners and confirm that it is aligned with the floor. If it is not, undo and try again. Use the Properties command to select all the elevation pieces to put them on the correct layer (i-wall-full-n).

27. Repeat this process for the remaining three walls. Change 3D Views or use Orbit to get the best view of each wall. Change the wall pieces to their correct layer with the Properties command. Be careful not to miss a step! NOTE: Each elevation will return to its original layer, which is layer 0. If you cannot see the elevation, thaw layer 0.

28. UCS, world

29. Plan, world

30. Vports, Three: Right

31. Put your crosshairs inside the upper left viewport and change it to a Front view

32. Put your crosshairs inside the right viewport and change it to a SE Isometric; leave the lower left viewport as a plan view

9

33. Freeze all layers except A-GLAZ-SILL, A-WALL-FULL, and S-COLS

34. Current layer: A-WALL-FULL

ADDING HEIGHT TO THE MODEL

35. Use the Properties command to change the thickness on the exterior walls to 12’8”. It may be easiest to pick the lines

from the plan view.

36. Use the Properties command to change the thickness on the east interior walls to the proper ledge height of 37”.

37. Use the Properties command to change the thickness of the 8 column lines to 12’8”.

38. Thaw layer: I-DOOR & CEILING

39. Use the Properties command to change the thickness on the doors to 7’5/8”. Do not alter the door swings (arcs). They will be left on the floor.

Note on Thickness: There is a command called THICKNESS. If you are drawing lines and they are appearing as 3D planes, check that the Thickness command is set to zero.

10

INSERTING & MOVING THE CEILING

40. Current layer: CEILING

41. Insert the Ceiling.dwg file (after you have downloaded it from the course website). Use

an insertion point of 0,0,0. Do not explode this block.

42. Freeze ALL layers except the ceiling.

You will move all of the ceiling components (tiles, speakers, and X lights) up to their correct Z height. Using a base point of 0,0,0 (the origin) allows you to quickly alter an object’s location, without doing complicated math or identifying the exact coordinates of the object(s). When you do this, you will see the ceiling change locations in the isometric and front views. The change may not be apparent in the plan view.

43. Move <- Select objects: window the entire ceiling or type ALL Select objects: <- Specify base point or displacement: 0,0,0 <- Specify second point of displacement:0,0,9’10” <- 44. Layer: Thaw: A-WALL-FULL and I-WALL-FULL-W Current: I-WALL-FULL-W Freeze: Ceiling

MOVING THE COAT RACK

45. Zoom closer to the coat rack in the isometric view.

46. Move the coatrack lines back to the wall surface.

Move <- Select objects: window the coat rack <- Select objects: <- Specify base point or displacement: 0,0,0 <- Specify second point of displacement or : 3’7,0,0 <-

47. Copy the coatrack lines forward 11-1/8” to make the front of the shelves. Copy <- Select objects: window the coat rack <-

11

Select objects: <- Specify base point or displacement, or [Multiple]: 0,0,0 <- Specify second point of displacement or : -11.125,0,0 <- (that’s a negative number for the X coordinate because you are copying it to the left of where it is now)

48. OSNAP: Endpoint 49. Zoom closer to the coatrack 50. Use the LINE command to draw lines to connect the shelves from front to back. Don’t forget to connect them on both sides of the shelves!

MOVING THE ALCOVE BASEBOARD

51. ERASE the baseline of the west elevation. That is the line that runs along the bottom of the wall. Do NOT erase the 9’10” ceiling line. You will break and move it into the alcove later. 52. View, 3D Views, NW Isometric 53. UCS, 3Point: Put the UCS on the east wall. 54. Zoom to the alcove and set the OSNAP to Intersection.

55. Break the baseboard at the edges of the alcove. Break <-

Select object: pick the baseboard line Specify second break point or [First point]: F <- Specify first break point: select the intersection of the baseboard line and the wall Specify second break point: selecting the same intersection again

56. Repeat the BREAK command and break the baseboard line at the other wall.

57. BREAK THE CEILING LINE IN THE SAME MANNER. You must do this while the UCS is parallel to the west wall. If the UCS is back on the floor in World position, repeat step 38 (UCS, 3point) to put the coordinate system back on the wall.

12

58. UCS, World 59. Move both the baseboard line and the ceiling line to the back of the alcove. You could also use OSNAPs to move it. Move <- Select objects: pick the baseboard line in front of the alcove and the ceiling line Select objects: <- Base point or displacement: 0,0,0 <- Second point: 3’7,0,0 <- 60. Draw lines from the endpoints of the back-baseboard lines to the front baseboard lines. Draw LINES to connect the ceiling line in the alcove with the ceiling line on the front of the elevation. 61. View, 3D Views, SE Isometric

MOVING THE WINDOW LEDGE

62. Thaw layer: I-WALL-FULL-E

63. Freeze all layers except A-WALL-FULL & I-WALL-FULL-E

13

64. Current layer: I-WALL-FULL-E

65. Zoom closer to the windows

66. Move the top line (#1) of the window ledge back 8”. Do this for

all three locations. DO NOT MOVE THE BOTTOM WINDOW LEDGE LINE!

Move <- Select objects: pick the top line of the window ledge in each location (#1) <- Select objects: <- Specify base point or displacement: 0,0,0 <- Specify second point of displacement or : -8,0,0 <- (this is a negative number because you are moving it in the negative X direction)

67. Now copy the middle window ledge line back (#2). You will leave a copy of this line on the front of the ledge so you can connect the edges of the ledge by the columns. Copy <- Select objects: pick the middle window ledge line in each location (#2) <- Select objects: <- Specify base point or displacement, or [Multiple]: 0,0,0 <-

Specify second point of displacement: -8,0,0 <- (that’s a negative number)

68. Draw lines from the endpoints of the lines in the back to the endpoints of the lines in the front (see illustration at right). Don’t forget the edges of the ledge in the corners by the north and south walls!

69. Move the dividers for the vertical blinds 8” back. These are the 3

vertical lines that separate the window blinds for each window. There are 6 sets of 3 lines each. Move <- Select objects: pick all the lines that divide the blinds (18 total) <- Select objects: <- Specify base point or displacement: 0,0,0 <- Specify second point of displacement or : -8,0,0 <- (again, a negative 8” back)

14

70. Move the horizontal lines at the top of the window openings and the east wall ceiling line.

Move <- Select objects: pick the 2 horizontal lines at the top of the windows <- Select objects: <- Specify base point or displacement: 0,0,0 <- Specify second point of displacement or : -8,0,0 <- (again, a negative 8” back) (NOTE: You may need to hold down the Shift key to select multiple lines!)

71. Draw vertical lines from the top of the ceiling to the ledges.

72. Zoom, extents

73. Thaw all layers and save this file!

TEMPLATE PRESENTATION

74. Open temp1117.dwg (from course website) 75. Edit the title block information in the lower right corner. Include your full name, student number, and date. 76. Tilemode to model space (pick the Model tab above the command line) 77. Current layer: 0 78. Xref the Bessey model to your template on layer 0, using 0,0,0 as the insertion point. Reconcile any layers as needed. 79. Tilemode back to paper space (pick the 11x17 Template tab)

81. Mspace (or click inside the mview)

82. Plan, world

83. UCS, world

84. OSNAP: Clear all active settings

85. Create the East Elevation with the Dview command. Dview <-

Select objects or : all <- Select objects or : <- Enter option [CAmera/TArget/Distance/POints/PAn/Zoom/TWist/CLip/Hide/Off/Undo]: points <- Specify target point <#, #, #>: place your crosshairs anywhere inside

the east wall and pick any point Turn Ortho on (F8) Specify camera point <#, #, #>: with Ortho on, move your crosshairs toward the center of the room and pick a point Enter option [CAmera/TArget/Distance/POints/PAn/Zoom/TWist/CLip/ Hide/Off/Undo]: clip <- Enter clipping option [Back/Front/Off] : front <-

Specify distance from target or [set to Eye (camera)/ON/OFF] <#>: ignoring the slide bar at the top of the screen, enter 6” to cut in front of the target (a good first guess for elevations is 6”)

If the view is not apparent (i.e. 6” was not enough to get you outside the wall), do clip, front again using 8”, 10”, etc. until the elevation is visible. Enter option [CAmera/TArget/Distance/POints/PAn/Zoom/TWist/CLip/

16

Hide/Off/Undo]: press Enter

86. Zoom, extents

87. Set the elevation to display at 1/8” scale (i.e, Viewport Scale: 1/8” =1’0”).

88. PAN as necessary to get the view

visible inside the mview, closer to the left edge.

89. Pspace (or click outside the mview)

90. Zoom, extents; Do NOT panic if the other drawings do not appear!

91. Zoom closer to the second mview.

92. Mspace (or click inside the second mview)

93. If the Bessey model is not visible inside the mview, force the

computer to regenerate the view. Regen <-

NOTE: You can also right-click on the viewport boundary, deselect and re- select the option "Display Viewport Objects - Yes" to make the elevation display again.

94. Plan, world 95. UCS, world

96. Create the East Elevation with the Dview command.

Dview <- Select objects or : all <- Select objects or : <- Enter option [CAmera/TArget/Distance/POints/PAn/Zoom/TWist/CLip/ Hide/Off/Undo]: points <- Specify target point <#, #, #>: place your crosshairs anywhere inside the west wall and pick any point

Regen Regenerates the current viewport

• The regen command forces a regeneration of your screen. This is useful when working with multiple mviews or with curving entities such as arcs and circles. The ability to maintain these curving shapes on-screen requires an extra effort from the program. Rather than burden down your drawing time by constantly curving these shapes, AutoCAD gets rather “lazy” and often displays curved objects as segmented or box-like. The regen command makes AutoCAD recalculate the virtual screen.

• A major disadvantage to Regen is the time delay. The bigger your drawing, the longer it takes to regenerate. • Related commands - - REDRAW & REGENALL - - can be found in the Appendix on the course website.

17

Turn ortho on (F8) Specify camera point <#, #, #>: with ortho on, move your crosshairs toward the center of the room and pick a point Enter option [CAmera/TArget/Distance/POints/PAn/Zoom/TWist/CLip/ Hide/Off/Undo]: clip<- Enter clipping option [Back/Front/Off] : front <- Specify distance from target or [set to Eye(camera)/ON/OFF] <#>: ignoring the slide bar at the top of the screen, enter 6” to cut in front of the target (a good first guess for elevations is 6”) If the view is not apparent (i.e. 6” was not enough to get you outside the wall), do clip, front again using 8”, 10”, etc. until the elevation is visible. Enter option [CAmera/TArget/Distance/POints/PAn/Zoom/TWist/CLip/ Hide/Off/Undo]: press Enter when you are satisfied with the elevation

97. Zoom, extents

98. Set the elevation to display at 1/8” scale (i.e., Viewport Scale: 1/8” =1’0”).

99. PAN as necessary to get the view visible inside the mview, closer to the left edge.

100. Pspace (or click outside the mview)

101. Zoom, extents

102. OSNAP: Endpoint

103. ORTHO: Off

Remember, when using stretch, you must cross over the corner of the mview with a crossing-window from right to left.

104. Use the Stretch command to make the mview smaller and to essentially “hide” the outside walls and ceiling space in each

elevation. Stretch <- Select objects to stretch by crossing-window or crossing- polygon... Select objects: pick a point near the upper right corner of the right side of one of the mviews Specify opposite corner: cross over the upper right corner of the mview window and pick again (Do not enclose the entire mview!)

18

Select objects: <-Specify base point or [Displacement] : pick the corner of the mview with your endpoint OSNAP Specify second point or : pick the corner of the elevation where the inside walls converge

105. Repeat the Stretch command to manipulate the other corner, hiding the outside wall.

106. Repeat the Stretch command to manipulate the second mview, hiding the outside areas of the second elevation.

107. Since the mview border (mview_elevation layer) is now overlapping the edges of the elevations, do NOT freeze it!

119. Mspace (or click inside the fourth mview)

120. Regen

121. Plan, world

122. UCS, world

123. Use the Dview command to create another section. Section BB is longitudinal, or cut through the room the long way.

20

Specify distance from target or [set to Eye(camera)/ON/OFF] <#>: ignoring the slide bar at the top of the screen, enter a small number to cut in front of the target (a good first guess for sections is 1/8”)

Enter option [CAmera/TArget/Distance/POints/PAn/Zoom/TWist/CLip/Hide/Off/Undo]: press Enter when you are satisfied

with the section You should be viewing the west wall, the one with the doors.

124. Zoom, extents

125. Set the section to display at 1/8” scale (i.e, Viewport Scale: 1/8” =1’0”).

126. PAN as necessary to get the view visible inside the mview, closer to the left edge.

127. Pspace (or click outside the mview)

128. Zoom, extents.

VIEWING PERSPECTIVES

A realistic representation of an object or space is the most effective way of showing a client what something will look like. Clients have a minimal knowledge of architectural graphics and often have difficulty understanding orthographic projections, such as plans and elevations. They better understand and can visualize drawings representing 3-dimensional spaces. A perspective is a view that represents looking through a 35mm camera. For more information on perspectives, refer to the Appendix, under Construction Drawings (available on the course website). You will create ONE two-point perspective view of your choice. You decide what to look at (target) and where to look from (camera). The perspective does not need to resemble the example presented at the beginning of this chapter. NOTE: A PORTION OF YOUR CEILING AND FLOORING MUST BE THAWED AND VISIBLE IN THIS DRAWING!

129. Zoom, extents

130. Mspace (or click inside the mview)

131. Plan, world

132. UCS, world

133. Use the Dview command to create a perspective view. The difference between presenting elevations and sections and presenting perspectives is the

21

addition of the Z coordinate. Whereas you picked X, Y points on the floor plan for elevations and sections, you will now need to type a Z coordinate for both the

target and the camera. A general rule of thumb for a realistic perspective is to keep the height of the target low (i.e., 18” - 36”) and the height of the camera (your eye) a bit higher (i.e., 48” - 60”)!

Dview <- Select objects or : all <- Select objects or : <- Enter option [CAmera/TArget/Distance/POints/PAn/Zoom/TWist/CLip/Hide/Off/Undo]: points <- Specify target point <#, #, #>: xy (there is a period in front of the XY) of Place your crosshairs at the spot where you would like to look and pick a point (need Z): make up a z coordinate for your target (usually between 18”-36”) Specify camera point <#, #, #>: xy (there is a period in front of the XY) of Place your crosshairs at the spot where you would like to place the camera and pick a point (need Z): make up a z coordinate for your camera (usually between 48”-60”) Enter option [CAmera/TArget/Distance/POints/PAn/Zoom/TWist/CLip/Hide/Off/Undo]: distance <- Specify new camera-target distance <#>: using the slide bar at the top, slowly move the diamond back and forth until the perspective appears as you would like it; the number 1 is the location of the target and camera points you selected; the closer you get to 0, the closer you get to the target and vice versa; be careful not to move the camera through the floor, ceiling, or walls by sliding too far to the right Note: While still in the Dview command, you can adjust the distance, pan, zoom or issue a quick hide to alter your perspective. Enter option [CAmera/TArget/Distance/POints/PAn/Zoom/TWist/CLip/Hide/Off/Undo]: press Enter when you are satisfied with the perspective.

134. You may need to go inside each mview and issue the REGEN command to ensure all views are correct and visible.

135. Thaw all layers. Freeze layer mview_sections.

NOTE: There needs to be a line at the bottom of both sections, especially section BB. If this line is not appearing below each doorway, confirm that the I-FLOR layer is thawed!

136. Plot this drawing to a printer of your choice. This may be printed black and white or in color. Print to an 11” x 17” piece of paper (try printing in the Design Building labs). Remember, use layout and keep the scale at 1=1.
