CREATING BASIC DRAWING OBJECTS IN AUTOCAD 2012

STEPS

CREATING A LINE WITH A SPECIFIC LENGTH.

CREATING A LINE WITH A SPECIFIC LENGTH AND ANGLE.

CREATING A CIRCLE WITH A SPECIFIC RADIUS LENGTH

CREATING A CIRCLE WITH A SPECIFIC DIAMETER LENGTH

CREATING A THREE-POINT ARC (DEFAULT ARC)

CREATING A SIMPLE RECTANGLE

CREATING A RECTANGLE WITH A SPECIFIC HEIGHT AND WIDTH

STEPS

CREATING A LINE WITH A SPECIFIC LENGTH

1) Goto Home Tab/ Draw Section. Click the Line icon.

2) Click a point on the drawing space. Drag the mouse away from the point (don’t lift the mouse button yet.)

Notice the length box appears above the line. We are going to specify the length (don’t lift the mouse button yet.)

3) Specify the length of a line.

Type 10 in the box and press ENTER (refer below)

4) Press ESC to stop drawing.

CREATING A LINE WITH A SPECIFIC LENGTH AND ANGLE

5) Repeat Step 1 and 2 length (don’t lift the mouse button yet.)

6) Type 15, Press Tab, Type 30.

7) Press ESC.

CREATING A CIRCLE WITH A SPECIFIC RADIUS LENGTH

8) Goto Home Tab/ Draw Section. Click the Circle icon.

9) Click a point on the drawing space,

move your mouse away from the point,

type 2 in the radius box,

and press ENTER.

10) Notice that AutoCAD records your input in the Command Window.

11) Notice also the text “or [Diameter]...”. It means that you can also enter a Diameter value instead of a Radius value. To do this, you have to enter a letter D followed by a value. (Clue the Command letter is always the first letter of the word in the brackets, ie [D...].

CREATING A CIRCLE WITH A SPECIFIC DIAMETER LENGTH

12) Repeat Step 8 and 9.

13) Press D and type 10.

CREATING A THREE-POINT ARC (DEFAULT ARC)

14) Goto Home Tab/ Draw Section. Click the Arc icon.

15) Click three consecutive points. AutoCAD automatically draws an arc based on the three points that you have clicked.

CREATING A SIMPLE RECTANGLE

16) Goto Home Tab/ Draw Section. Click the Rectangle icon.

17) Click a point on the drawing space and move the mouse away from the point.

19) Click another point to specify the rectangle dimension.

CREATING A RECTANGLE WITH A SPECIFIC HEIGHT AND WIDTH

19) Repeat Step 16 and 17.

20) Type 10, ENTER, 6.

21) Take note that AutoCAD draws a rectangle with a width of 10 and height of 6. By default, the generated edge point is placed towards upward and rightward from the starting point.  

22) Repeat Step 19 again. This time type 10, ENTER, -6. What is the result?

The new rectangle goes downward as oppose to the previous rectangle.
