Lecture 5

 

Using of Commands:-

We are now at the stage to draw some drawings. Many new commands will be introduced while drawing.

Wall Footing:-

So let us start with wall footing. It is a common kind of foundation. [Save this and every drawing after this as it will be used in future lectures)

1. Start the AutoCAD and set the units. But in units to scale drag and drop content should be centimeters. You might be asked to ensure that you have selected centimeters; click on OK.

2. Save this drawing by the name of

 3. Type l(enter). (Here we are making a rectangle of 70x15 cm)
4. Select any arbitrary point on screen.
5. Press F8 to straight the line (i.e. to ON the ortho, if it is OFF).
6. Now move the mouse towards your left or right and then type 70(enter) (It will act as our mirror line).

7. If you are unable to see the line, type z (enter) and then a (enter)to zoom all.
8. Now similarly make the breadth of rectangle 15 and further complete the rectangle as shown in Fig-w-01
9. Now make sure that in the object snap dialog box (type os (enter)for object snap dialog box), the Midpoint is checked and the oSNAP tag at the status bar is pressed in i.e. OSNAP is ON (we can also use F3 to ON/OFF the OSNAP).

10.Type l (enter) and move the cursor on the somewhat mid of  the top line of the rectangle. Here we will see a rectangular shape marked as Midpoint as shown in Fig-w-02. Using this midpoint, draw a line of approximately 50 as shown in Fig-w-03.

11. Now type o (enter) for offset. Type offset distance as 15¿. Then select the left side of rectangle and then move your cross hair towards the right an click. The command will be still active, so select the right side of the rectangle and move your cursor towards left and click on screen. Press enter to deactivate the command. You will now see the drawing as shown in Fig-w-04.

12. Now we got 15cm mark from the either sides. Type pl¿ for polyline and select left top offset, move your cursor (or you can say cross hair) upward and type 10¿. The command is still active, so move your cursor towards right and type 5(enter). Then move your cursor toward upward and type 10 (enter). Again move your cursor towards right and type5(enter). Now move your cursor upward and type 30 (enter) as shown in Fig-w-05

13. Type mi(enter) for mirror. Select the Polyline which has been drawn in above step and press enter. Now select the end points of the midline which was drawn is step no. e. then type no(enter) (or simply n) to avoid deleting our source Polyline. The Figure will be as shown in Fig-w-06
