1. Sketch and procedures:

Aim: To sketch the layout of a residence as shown in the Figure 1.

Consider all dimensions as reference to sketch the unit plan. Also the text in the layout are only for reference. Assume the missing dimensions. Also, refer the schedule for size of the doors.

(i) Sketch 1: Residence layout:

Procedure:

Set units to "Engineering". Type "dimstyle or D" in the comment line and then press the Enter. The Dimension Style Manager window will appear.

Select the modify option or overrides option.

In the new window, go to the "Primary Units" tab and then from there change the units to Engineering units.

Now create the boundary of the given plot by using the rectangle tool. Now create a rectangle using the rectangular tool with 25' width and 43'-6.5" length.

Now create the outer walls. Use the offset command and offset the rectangle by 9". After creatin the inner rectangle. Select all and then use the Explode command to explode the rectangle/onject. This will rendered the rectangular object into the seperated lines.

Create the inner boundary of the Bedroom#1. Select the left inner wall and then use the offset command to offset it by 11'-7.5". to the right. Select the upper inner wall line and use the offset tool to offset the upper wall by 12' downwards.

Now trim the edges using the fillet tool with 0 radius to create the inner boundary of the bedroom#1.

Now create the inner boundary of the bedroom#2 using the offset tool.

Select the right inner wall of the bedroom#1 and then use the offset command to offset it by 11'-6.0" to the right. Select the upper inner wall line and use the offset tool to offset the upper wall by 12' downwards.

Now trim the edges using the fillet tool with 0 radius to create the inner boundary of the bedroom#2.

Create the inner bondary of the toilet#1. Select the lower outer wall of the bedroom#1 and give offset of 4'-6" downwards. Select the left inner wall of the boundary and offset it by 8'-30" by right side.

Trim the edges to create the inner boundaries of the Toilet#1 .Again do the same procedure as we have done in the bedroom#1 to create the wall of the toilet.

The inner wall thickness is 4.5".

To trim the edges,use the trim command. Type trim in the command line and then press Enter. Trim command invokes and then we can use the trim command for trimming the edges.

Select all the unwanted edges and then press enter.

To create the corner of the rectangle,use the fillet tool of radius 0.

Proceed with the door openings. Select the right inner wall line of toilet#1. Offset or copy the line 2'-6" to the left using offset tool or copy tool. When using the copy tool, make sure the ortho mode is ON.

Also extend the right inner line of the bedroom#1 wall using the extend tool. To extend the line, select the Extend tool and then press enter to select all the boundary edges.

Using the trim tool,trim the unnecessary lines. Type the trim in the command line and then press Enter.

Select the inner wall of the toilet#1.

Select the mirror tool.First point of mirror line: Centre of vertical inner wall. Second point of mirror line: Any point downward. Make sure Ortho Mode is on.

Use the fillet tool with radius 0 to enclose the rectangle. This is the toilet#2 area.Above this area there is Bedroom#2.

Now extended the lower inner line of toliet#2 to the outer line.

Once it is extended,select the line and offset it by 2'-6" in the upward direction.

Select trim tool and then press the enter to select the all as cutting edges. Delete the unwanted lines to form the opening of the Toilet#2.

Using the offset or copy command,create the wall lines for the below area.

Select the two lower external lines of the Toilet#1 and Toilet#2.Select copy tool and point downwards (Ortho mode should be ON). Offset distance is 11'.

Using the similar method. Select the copy or offset at 4.5" for the two new created lines and 9" for the right line.

Using the copy tool,copy the created line object on the left 6'-8" in the downward direction.

Copy the new created line by 9" in the downward direction.

For the staircase use the line tool to connect the lower tight corner of the kitchen wall to the corner created below when the outer wall is trimmed.

Create the stairs.

Using the move tool, move the boundary line in the below image 9" to the left.

Select the same line and then select the tool command and then press enter.

Set 12" or 1' as the offset distance.

Select the Multiple to apply the consecutive offsets to the given offset distance.

Do the offset until we finish the 8th step.

Select the middle line and offset it 1" in upward and downward direction.

Using the trim tool,delete the unwanted vertical lines inside the horizontal lines.

Usin the line tool to enclose the horizontal lines.

Move the left line 1" to the left and trim the horizontal lines on the left.

Using the line tool connect the corner edges.

Add an arrow at the middle of the stairs to show its direction.

Make the upper lines of the stairs as the hidden type.

Now create the opening of the kitchen. Select the right outer wall of the kitchen and copy it to 6'-4" to the left direction.

Using the trim tool,delete the unnecessary lines for the kitchen.

Create the kitchen counter,select the inner wall of the object of the kitchen and offset it by 2'.

Copy the lower external wall of the kitchen to the 3' in the downward direction.

And extend the right inner line of the outer boundary wall in the downward direction.

To finish the kitchen counter table use the fillet tool with radius 0.

For the parking area,use the trim tool to delete the inner line of the outer wall.

To create the door symbols,follow the steps below:

On the corner of the opening,create a rectangular object with dimensions 1" width and 3" length.

Add the hinge symbol by adding a horizontal line in the middle of the rectangular object. The line length can be of any length, but here we assume as 1".

Make a vertical line connecting from the horizontal line towards the horizontal line towards the direction of the door opening.

Make a circle with the endpoint of the horizontal line as the centre. Specify the radius of the circle as the midpoint of the rectangle on the opposite corner.

Extend the vertical line to the circle and trim the outer edges to form the arc. Use vertical line and rectangle object touching the circle as the cutting edges.

Now trim thr unwanted lines and arcs using the trim command.

Now do these steps to create the all the doors sizes.

Continue the sketch. Create the doors at their specified locations.

Now create the cabinet in the bedroom#1 and bedroom#2.

For this select a rectangular tool. The first corner is the lower left corner of the bedroom#1. Rectangle dimensions are 5'-6" X 1'-6" these are the standard dimensions.

Offset inward by 1" to create the cabinet boundaries.

Select both the rectangles and copy it to the lower right corner of the bedroom#2.

Trim the unwanted lines from the outer walls.

Now add the text using the text tool.Select the text tool and specify the start point of the text within the walls.

Specify the height of the text as 6" or any desired height.

Use the dimlinear tool to add the dimensions at the desired points.

Final result:

2. Sketch and Procedure:

Aim : To sketch the seating plan for an outdoor canopy. Assume the dimensions for the seating. Also, consider the dimensions in mm.

Procedure:

The dimensions that are used in this sketch is assumed and is given below: All the dimensions used in this sketch is in mm.

Firstly sketch the seat. To sketch a seat we need a rectangular tool. So select the Rectangle tool and make a rectangle with 400 dimension.

Create a circle inside this rectangle with 400 units diameter.

To create a circle we need a circle tool. Type C or circle in the command line and then press Enter.

Now specify the centre point of the circle, as the centre of the rectangle.

Select the diameter and specify the diameter as 400.

Select the trim tool to delete the all unwanted lines from the geometry.

Now type trim in the command line and then press Enter.

Now delete the outer rectangle of the geometry on the top and the inner circle of the object on the bottom.

Select the semi circle object. Select the offset too.

Specify the offset distance as 20 and then click outside the object.

Now select the created semi circle object and using the same method. But this tyme give the offset of 40 units.

Close the two outer semi circle by using line command.

Create a rectangular object on the lower left part of the semi circle.

Select the rectangular tool. Specify the lower left point of the outer-semicircle as first corner point.

Dimensions of the rectangle are 40 units and 120 units.

Move the rectangular object 20 units in the downward direction.

After moving the rectangular object in the downward direction,mirror the object with the mirror plane located vertically in the middle of the object.

Finish the skech of the seat by doing a fillet on the lower corners of the rectangle.

Select the fillet tool.Specify the radius of the fillet as 80 units.

Fillet the lower corners of the rectangle.

Using the centre of the seat as the centre of the sketch. Create a circle with 452 units of diameter and 1398 units of diameter.

Move the block 800 units upward.

Using array tool. Select the polar sttings.

Specify the centre of array as the centre of the sketch or we can say that the centre of the circle.

Select the item options.

Enter number of items as 4. Continue pressing the enter to end the command.

Use Dimradius command to identify the radius of the circle.

Final Result:

3. Sketch and Procedure:

Aim: To sketch the part plan for the toilers and utilities room.

Consider the outer wall thickness as 300mm and inner wall thickness as 150mm. Also, assume the missing dimension, Texts, dimensions, and hatches are only for references. Also, symbols for toilets and w/c are also for references.

Introduction:

• A toilet room usually consists of lavoratory and all the accessones such as grab bars and dispensers.
• There are many types of this layout but here we are using a very simple layout.
• This room contains laundary equipments such as washing mashing,dryer, ironing boards and space for ironing the clothes.
• The utility room has several uses but typically functions as an area to do laundary.
• This room is also used for closet organization and storage.

Procedure:

Firstly draw a rectangular object or the outer wall of the toilet and utility room.

To draw the outer wall of the toilet we use rectangular command.

Type REC or rectangle in the command line and then press enter.

Create a rectangle with dimension 1900X1700 units and 1900X2100 units spaced at 150 units vertically. This will specify the inner dimension of the toilet and the utility area.

Now select these two rectangles and use explode command to separate the line objects.

Offset the upper and left line by 300 units while the right and lower line by 150 units.

Use the fillet command with radius 0 to enclose the lines.

Create the windows and the doors opening.

Using a line tool, create a line object at each corner of the openings.

Now trim the all unwanted lines to make the opening of the doors and windows.

Create the window on the upper opening.

To create a window use rectangle tool. Type REC or rectangle in the command line and then press Enter.

Now create a rectangle of dimension 50X100 units.Specify the first point of the rectangle as the midpoint of the line enclosing the opening.

Use copy tool to create the rectangle object on the other side.

Now create another rectangular object using the rectangular tool with dimension 531X25 units with the upper corner of the created rectangle to the lower corner of the another rectangle to finish the window.

Now create the window on the right side.

Select the rectangle tool and create a rectangle of dimension 40X40 units.

Move the rectangle object 30 units right and 30 units below.

Using line tool create a line connecting the upper corner of the rectangle horizontally to the left line of the opening boundary.

Create another line using the midpoint of the line of the rectangle as the first points connecting perpendicularly to the right line of the opening boundary.

Mirror the created objects on the other side of the opening boundary.

Use the centre plane of the opening boundary horizontally as the mirror plane.

When the mirror object is created,connect the centre points of the rectangle object using the line tool.

The windows are created as shown below.

Now create the door for the utility room.

Create a line using the line tool.

Specify its first point as the centre of the lower line of the opening boundary with the length 100 units.

At the upper endpoint of the created line,make a horizontal line object with any length.

Copy this line by 50 units in the downward direction.

Create a circle using the circle tool with the endpoint of the vertical line as the centre point.

Click on the midpoint of the upper line of the opening boundary as the mid point of the circle.

Extend the upper horizontal line to the edge of the circle object.

And then trim the outer portion of the circle using the trim command.

Do the same procedure to create the door for the Toilet area.

Create the text to identify the different areas Select text tool specifying any points within the area as starting point.

Specify text height as 100 units and rotation angle as 0.

We can enclose the text by using line and rectangular tool.

To create the upper right part.

Select the rectangle tool and specify the upper outside corner as first corner point.

Create a rectangle with the dimensions 702 X 351 units.

Explode the rectangular object. And then use the offset command to offset the outer lines inward by 150 units.

Now trim the all unwanted lines using the trim tool.

Add the dimensions using dimlinear command and finish the sketch.

Object inside the Toilet area are for the reference only.
