FLOOR PLAN LAYOUT
STEP 1:
Create the basic template:
ü Title block and border
ü All layers you will use in the drawing
ü Pen table (DSN 204) color based
ü Text styles
ü Dimensions
ü Units
ü Limits (the default value is <1’-0”, 0’-9”>, this is the opportunity to change the size of your drawing area to fit your current project. ON will keep the default value. OFF will disable limit checking but retain the limit values for future use of limit check) AutoCAD 2004 for Architecture. Alan Jefferies, Michael Jones, Tereasa Jeffris.
ü Set the scale factor
STEP 2:
Consider the orientation of the house. There are two standard ways:
1) A common method is to draw the house on the sheet with the entry door at the bottom of the sheet. (CHOOSE THIS ONE)
2) Another method is to place the house on the sheet with the north direction pointing toward the top of the sheet.
STEP 3:
§ Lay out exterior walls 5-1/2” and interior walls 3-1/2”. Use the Wall layer.
§ Start with all the horizontal walls continue with vertical walls
§ Review overall dimensions of the house according to the drawing given in class. Avoid using fractions i.e. 45’-0”; 45’-6”; 45’-9”; no 45’ 6-1/8”; 9’3-1/4”.
§ Use commands like TRIM or CHAMFER (Dist 1 and 2 = 0’-0”) to remove lines from walls intersection
§ Draw the fireplace. (See textbook for details)
STEP 4:
§ Block out all doors and windows in their proper locations. Create the templates according to the directions given in class. Use the corresponding layers, colors and sizes.
STEP 5:
§ Draw cabinets. Base kitchen cabinets D = 25-1/2” (countertop dim.); H = 36”. Counter layer, color by layer, and continue line. Upper cabs D = 12”. Discontinues line. Bathroom cabinets vary.
§ Draw closets according to the directions.
STEP 6:
§ Draw all appliances and utilities. Appliances layer.
§ Use the AutoCAD symbols. Check their dimensions.
STEP 7:
§ Draw stair. 10-1/2” wide treads. Stair layer, color by layer. Handrail: Handrail layer, color by layer. Draw arrow (up or down). (See textbook for details and specifications)
STEP 8:
§ Check the accuracy of the drawing.
o Turn off layers to check that you are using the correct layer for each element of the drawings – Go to Layer Properties Manager; set the layer you are going to check as a current layer; right click, select all but current; turn off the other layers- when you finish checking the layer, turn back on the other ones.
o Check the line types of the drawing.
STEP 9:
§ Draw hatch patterns. When you draw patterns before including symbols, notes and numbers, the pattern will be visible under this information. If you place the patterns after the other information there will be a blank area around it.
STEP 10:
§ Label all rooms using an 8” text size. Create a Label layer color 150.
§ The interior room dimensions may be place between the room name and room number. Use a 6” text size, Text layer and color by layer.
§ Letter the title of the drawing. Use a 12” size text, Title layer, Arial black font, and color by layer.
STEP 11:
§ Draw symbols schedule key. Doors: a circle 14” Diameter; Windows: a rhomb inscribed in a circle of 10” radius, Plumbing: a hexagon inscribed in a circle of 8” radius. Room Number: a rectangle 18”x 10”. Create a Symbol layer, color red.
§ Complete the information about:
o Number of door, windo w and plumbing fixture. Start from left-top corner to right always trying to keep a clear sequence.
o Door sizes
o Windows commercial reference.
o Room number. Use 100 as a first number for the first floor and 200 for the second floor.
STEP 12:
§ Place dimensions. Dimension layer, set dimension style.
§ The exterior dimensions go from particular to general dimensions:
o First line: corner of the house to center of windows and exterior doors.
o Second line: rooms dimensions
o Third line: from exterior face to exterior face of major jogs.
o Fourth line: overall dimensions
§ Interior dimensions:
o Lay out dimensions as needed
o Do not dimension cabinets or appliances but to the immovable elements as walls and stairs, doors and windows openings.
STEP 13:
§ Specifications notes (See textbook for details).
SCALE FACTOR
LETTERING HEIGHT LINE TYPE SCALE
Drawing Scale Text Scale LTSCALE
1” = 1’ – 0” 12 6
3/4” = 1’ – 0” 16 8
1/2” = 1’ – 0” 24 12
3/8” = 1’ – 0” 32 16
1/4” = 1’ – 0” 48 24
1/16” = 1’ – 0” 64 32
1/8” = 1’ – 0” 96 48
3/32” = 1’ – 0” 128 64
1/16” = 1’ – 0” 192 96
¼” x scale factor = 1’ – 0”
.25” x scale factor = 12” (convert to inches)
Scale factor = 12 / .25
Scale factor = 48
To determine the required text height:
Multiply the desired height (1/8” plotted) by scale factor.
For drawings at ¼” = 1’ -0”
1/8” (.125) x 48” = 6” Text height
LINETYPE
The linetype scales is determined by the size the drawing will be plotted at.
For a drawing to be plotted at ¼” = 1’-0”, a dashed line that should be 1/8” when plotted, would need to be 3” long when drawn a full scale.
1/8” x scale factor
.125 x 24 = 3”
PSLTSCALE: 0
No special linetype scaling. Linetype dash lengths are based on the drawing units of the space (model or paper) in which the objects were created. Scaled by the global LTSCALE factor.
PSLTSCALE: 1
Viewport scaling governs linetype scaling. If TILEMODE is set to 0, dash lengths are based on paper space drawing units, even for objects in model space. In this mode, viewports can have varying magnifications, yet display linetypes identically. For a specific linetype, the dash lengths of a line in a viewport are the same as the dash lengths of a line in paper space. You can still control the dash lengths with LTSCALE
