- Step 1. Set LIMITS to 60 x 60 drawing units, set GRID
and SNAP spacing to 2.0 units, then set GRID and SNAP to ON, in
order to display the grid and enable Snap to the Grid points.
If there is an error message that says there is insufficient
resolution to display the grid, try (a) zoom factor = 2, or (b)
grid/snap spacing = 4. If the LIMITS command does not work,
then check the drawing size and scale your drawing to the
existing limits. CIRCA may have set for another class the
limits you see as defaults on your workstation.
Step 2. Draw a bounding box for the drawing using the RECTANGLE command. The bounding box should leave about 1 inch margin around the edge of the 8-1/2 x 11 inch sheet of paper.
Step 3. In the lower right-hand corner of the box drawn in Step 2, draw a small box that will appear 0.75 inch high and 3 inches long on the final drawing, similar to Project #1. You have to figure out how to scale this, so that the bounding box drawn in Step 2 prints out at approximately 6-1/2 inches by 9 inches on the 8-1/2 x 11 inch sheet of paper.
Step 4. Draw the outline of the house (as shown in Figure 1, below) using single lines, and preserving the position of doors and windows. Size of the house is approximately 50' North- South by 50' East-West, including the bay window. Windows are filled in white in the illustration of Figure 1, so you can see them more easily. In your drawing there should be only black lines and white background. Use the LWT button at the bottom of the AutoCAD interface to show the different lineweights, which you can select from the lineweight pulldown menu, as we discussed in class.
Step 5. Draw the doors and partitions as shown in Figure 1, with the room dimensions as shown in Figure 1. Use the ARC command to draw the path described by the door edge, as shown in class. The front door and all doors to the porch must be a double door, and it must be drawn as being closed. (All exterior doors, including the door to the garage are typically represented as normally closed). This is shown in Figure 1 by putting a line across the door opening where the doors would close. You will have to set SNAP to OFF to do some of this, especially the arcs for the doors.
Step 6. Put in the windows using thin rectangles drawn using the RECTANGLE command. Fill in the floor tiles using the HATCH command, and appliances, including bathroom sink, toilet, and shower or tub, using the LINE, CIRCLE, or ELLIPSE commands, as shown in class. Again, you will have to set SNAP to OFF for some of this work, and you should use ZOOM to magnify the drawing big enough to draw the stove burners, sink basins, etc. in their correct places.
Step 7. Fill in the names of the rooms, using the TEXT command, and insert the room dimension similar to what is shown in Figure 1. It is important to note that the room dimensions given in Figure 1 are not necessarily correct - you need to figure out the dimensions for the house that will fit into a 40x50-foot bounding box.
Pay special attention to making the text approximately the same size in proportion to the drawing as is shown in Figure 1. You can use Text, Roman, Arial, or Helvetica fonts for this. Also, you must calculate the room dimensions for the major rooms in which there are no dimensions, and insert the dimensions you calculated in these spots. For example, you must calculate the dimensions of the master bathroom and kitchen.
Step 8. After setting GRID and SNAP to the OFF position, set the TEXT height parameter to 0.15 or 0.2 inches (or whatever appears that height if the drawing is scaled differently due to CIRCA preset values). Then, place your name and last four digits of your UF ID number in the top half of the box drawn in Step 3. In the bottom half of the box, place the following text: "CGS2470-P3-F08".

Project #3: Floorplan of a small house -- not drawn to scale, and
boundary box not included.
Qualifications. Because the setup of AutoCAD software appears to vary among CIRCA laboratories, you may not be able to get thick lines, or dotted lines, as shown in Figure 1. Thus, you must check the LWT button at the bottom of the AutoCAD screen - if the button is pushed in, then the Lineweight feature is on.
Appearance. Print out your draft versions (the ones you use for making corrections) using the dot-matrix printers. Print your final version (the one you hand in) using a black-and-white laser printer. Make sure the drawing is centered in the middle of the page. You may rotate your drawing 90 degrees or 270 degrees, if needed to center the drawing on the paper. You can perform these rotations using the PLOT command dialog box, with the landscape and portrait options and the upside-down setting.
Grading. The maximum number of points is 100, allocated as follows:
Bounding Box and Text Box . . . . 3 points Name and CGS2470...in Text Box . . 2 points Exterior walls as shown. . . . . . 15 points All windows placed correctly . . . 10 points Front door drawn as shown . . . . 5 points Internal partitions as shown . . . 20 points Doors as shown . . . . . . . . . . 15 points Room names and dimensions . . . . 10 points Appliances/fixtures as shown . . . 15 points Vertical text in bath & laundry . 5 points -------------------------------------------- TOTAL 100 points
Hardcopy. The completed project (drawing) should be printed on a black-and-white laser printer. Use black for the lines and white for the background. Do not hand in a Xerox copy or printout of Figure 1 -- if you do, it will be regarded as cheating.
Items Due. Give the instructor your completed project in class on Tuesday 30 September 2008. Projects turned in a day late will be penalized -10%; two days late: -20%. Projects turned in more than two days late will not be accepted unless accompanied by a documented excuse (note from your physician or advisor).
