3. Drawing form fields and Forms Three Dimensions
Drawing angle Moving angle
Create an arc with A as the center of radius R cut any legs AB and AC point in n and m
Create all of the A1 arc of radius R1 (R = R1) that cut leg angle A1 C1 in m1
Create a circular arc with radius r = nm
Create an arc with the same radius of r1 = r m1 point in this arc cuts the first arc (radius R1) at the point n
Pull the line A1 n1 which is the foot angle A1 B1

5. Dividing Two Angle Angle Being the Same Great
A circle arc to point A as a center of radius R cut any corners leg AB and AC at points P and O
Start with P and O as the center of the circle arc with any radius R2 and R3 (R2 = R3) are equal. The second arc intersecting the circle at T.
Pull the line AT BAT angle = angle TAC

7. b. Drawing Triangle
To be able to draw a triangle then it must be determined at least 3 pieces so that the triangle can be made according to the desired.
The elements that can be used as a guide in drawing a triangle if specified: Side angle side
Start by measuring the line AB measurement line with the term 1
Move the angle which is determined by measuring the sequence 2, 3, 4 and 5 at point A
Long lines Ukurkan size 6 to a line that has formed angle at point C
Triangle ABC is drawn (figure 2.4)

8. Start by measuring the line AB measurement line with the term 1
Angle side angle 
Start by measuring the line AB measurement line with the term 1 
Move the angle which is determined by measuring the sequence 2, 3 at point A and the sequence 4, 5 at point B 
The second meeting point of forming lines cut point C

11. Determine or measure one side for example AB
This triangle is an equilateral triangle because the three sides the same length 
Determine or measure one side for example AB 
Measure the order of 1 from point A along the line AB 
Then come back ukurkan sequence 2 from point B along the AB

13. Determine the circle with center M
Square 
Determine the circle with center M 
Pull the center line cut points A and B 
Wrapping the fingers of the points A and B are the same length 
Connect the intersection of the circle from point A and B, so determined to cut the circle at point C and D 
Points A, B, C and D are connected to form irregular rectangle or square

18. Drawing a tangent to circle
Determined point P and the circle centered at point M
Drag from point M to the P and determine the value of N in the middle between the MP line. Way for the same arc from point M and from the point P to the intersection of the bow when drawn line would cut the line at point N MP
Create a circle as the center point N with a radius of NP or NM
The circle is cut the first circle at point R1 and R2
PR1 and PR2 lines are tangents to circle

20. Five Aspects Drawing Irregular
Determined circle with center M
Pull the center line through M cuts the circle at point A and point B
Make the same arc from point A and point B. The intersection of the arc in a circle to cut the line pull at point C and D and the point M
Then make the same arc at the point M and point B. The intersection of the arc to cut the line drawn at point E
Connect the line from point E and point D
Round from point E along the ED to the Supreme Court until the cut at the point F DF is a side line of the regular pentagon
And so on round the sides of the circumference of a circle will form a regular pentagon

22. Drawing ellipses
Divide the axis AB in the same length 4, then the obtained points M1, M2, M3 and M3
Draw a circle 2, 2, and 3 with a radius of ¼ length axis with the circle center point M1, M2, and M3
Three circles intersect at point C, D, E and F
Pull line M1C, M1E and M3D, which cut M3F circumference of a circle at point G, H, I and J
M2C and M3D line intersecting at point N1, while M1E and M3F intersect at point N2
Points N1 and N2 as the center of the arc Bh and LJ

24. Drawing Parabola
Draw a line parallel to the upright support 10 parts with the same distance
Create help lines are also parallel to the direction of the horizontal part of the same length 5
Horizontal distance is wider than the vertical distance
Connect from the 0 point to point 1, 2, 3, 4 and 5 also connect the middle or the line from point to point 5 was 1, 2, 3, 4 edge
Results will pull the line straight line dipotongkan ie 01, 51 with a vertical line A, line 02, 52 with a straight line B, line 03, 53 with a straight line C and line 04, line 54 with a peak D and E5 line
The intersection of these lines is the point of connection in the manufacture of parabolic lines

28. Drawing Isometri Selinder
All you need to understand is the line connecting the top and bottom of the circle is the intersection point of the circle
To be able to load without the need to run with the help lines
Create square
For the square into 4 equal parts of both the horizontal length and vertical directions
Help lines connecting the center to the corner diagonal from the square to 4 parts
Connect the help lines from the middle to the side of the intersection for the four parts
The results point to the intersection of the sides 4 and the 4 points of intersection that are connected to form a circle.

29. To create a isometric ellipse, without must run with the help lines.
Create a isometri square
For isometric square into 4 equal parts of both the horizontal length to the corner toward the left or right corner
Connect the help lines from the center to the corner diagonal from the square isometric to 4 parts
Connect the help lines from the middle to the side of the square isometric intersection to the four parts
The results point to the intersection of the sides 4 and the 4 points of intersection that are connected to form the ellipse
For cylindrical shapes to make 2 pieces ellipse bottom and top In order to fit the ellipse form a line drawn connecting the intersection altitude
