If you are interested in the question of how to make an unfolded cylinder surface on your own, without using these calculators, then the next article is for you.

A cylinder is a simple geometric figure, which is an elongated body bounded on both sides by two planes (bases).
For ease of presentation, a straight pipe is a cylinder.
Figure 1 shows a right circular cylinder. Right - means that the angle between the axis of the cylinder and the plane of the base is right (equal to 90 degrees), circular - means that the base of the cylinder is a circle.

To construct a hollow right circular cylinder from a sheet, two quantities are required:
1) cylinder height (H),
2) the diameter of the circle that lies at the base (D),

Go to build.

The cylinder may not be circular. For example, figure 2 shows an elliptic cylinder. Elliptic - means that the base of the cylinder is an ellipse.

Also, the cylinder may be oblique. In an oblique cylinder, the angle of inclination of the axis is acute (less than 90 degrees). Figure 3 shows an oblique cylinder.

Three sizes are used for the hollow oblique cylinder design from a sheet:
1) cylinder height (H),
2) circle radius (R),
3) the angle of inclination of the axis (A),
Go to build.

If you unfold the lateral surface of the oblique cylinder, as in figures: 9 and 10. Then you get the the flat form which shown in figure 11.

Let's build the unrolled curved surface of the oblique cylinder (online calculator).

The unfolded lateral surface of an oblique cylinder is more complicated than that of a right circular cylinder and is limited above and below by smooth curves. Ellipses is located at the bases of an oblique cylinder (top and bottom).

Let's build the unfolded lateral surface of the right circular cylinder (online calculator).

As can be seen from Figure 8 (above), all surfaces of right circular cylinder consist of two parts:

  • the lateral surface of the cylinder, which is a rectangle,
  • two circles that located at the bases of the cylinder.
Dimensions of the rectangle (lateral surface of the cylinder):
1) the height of the rectangle is equal to the height of the cylinder (H),
2) the length of the rectangle (L) is equal to the circumference of the base:
L = π × D ,         where D is the diameter of the circle and π = 3.14159 (pi number)

Let's move on to building the unfolded lateral surface of the right circular cylinder (online calculator).

Let's build the unfolded lateral surface of the oblique cylinder (online calculator).

As can be seen from Figure 11 (above), an unrolled curved surface of an oblique cylinder is more complicated than a right circular one and consists of a flat form bounded on both sides by splines. And two ellipses. To build a spline, we divide the circle (with radius R - Figure 3) into a multiple of points, and then for each point we determine the coordinates. We will proceed in a similar way to construct ellipses. To switch to automatic computation, click unfolded oblique cylinder - online calculator.
