Type L in the command line and press Enter.

Specify the start point i.

Specify next point:@.12, 0

Type O or offset on the command line and press Enter.

Specify the value of offset distance:.20

Select the object to offset ij

(We need to select the line ij with a small square cursor.)

Move the cursor inside to place the line and continue till required.

Give the dimensions as per the drawing using dimension command from the command bar.

The C.S of the isolated footing is completed

Isometric view of steps.

Aim: To draw the isometric view of steps.

Commands used:

• Line.
• Isometric plane.

Procedure:

1. To work with isometric view -command "ds" - snap off, grid off. Put isometric snap on .
2. Make sure that ortho mode is on .

Step :1 - From isometric drafting select iso-plane left.

• Give command "l" and moving the cursor to -x direction(left) give 1unit .
• Moving the cursor to+ y direction (top), give 0.15 units.
• Moving the cursor to + x direction again give 1 unit and cursor to -y direction(downwards) give 0.15 unit.

Step:2 - Change the isometric drafting to iso-plane top

• Move the cursor to back and give 0.3 units from the last drawn point.
• Move the cursor to right direction and give 1 unit.
• Move the cursor to front and give 0.3 unit.

Step:3 - Change the isometric drafting to iso-plane right

• Copy the object drawn, ortho off .
• Command "co" and specify the base point and place it to new point.
• Repeat it until 4 steps are formed.

Step:4 - With iso-plane right join the two ends with ortho off.

Result: The steps are drawn in isometric view.

Isometric view of gable wall.

Aim: To draw the isometric view of gable wall.

Commands used:

• Line.
• Isometric plane.

Procedure:

1. To work with isometric view -command "ds" - snap off, grid off. put isometric snap on
2. Make sure that ortho mode is on

Step:1 - From isometric drafting select iso-plane left.

• Give command "l" and moving the cursor to right give 1 unit
• Pointing the cursor upwards give 3 units
• Draw 0.3 units to left and 3 units downwards and 0.3 units to left.

Step:2 - Using isometric right, take line command and draw line upwards of 2.42 units from the starting point of step 1

• Draw 1 unit towards the right and 2.42 units downwards.
• Using isometric left again, using line command draw 0.3 units to left side and draw a line which intersects the top line.

Step 3 – Using iso-metric right with the line command draw 1.0 unit to right Side and 3.0 units upwards.

Step:4 - By using the line command draw a line from bottom left corner @1.5 units and extend line 4 units upwards i.e., total 3.25 units from bottom.

Step :5 - With ortho off, draw a line between the corner of left side and the projected line done in step 4

• Draw it to the other side also till it meets the right corner.

Step:6 - Draw the vertical line with ortho on @0.3 and join the vertical line using line from left and right end same as in the step 5 remove unwanted lines by using erase.

Result: The isometric view of gable wall is draw
