Circular cylinders and prisms, representation

Circular cylinders and prisms can be represented lying or standing in the oblique image or in the two-panel image. In cavalier projection - do my homework , the oblique image is displayed very clearly.

In a vertical two-panel projection, the representation takes place simultaneously in two planes.

Circular cylinders and prisms can be displayed lying or standing in the oblique image or in the two-panel image.

The oblique image of a lying circular cylinder is obtained as follows :

- The base area is drawn and the centre point is entered.

- The centre of the top surface is determined by drawing the oblique image of the axis.

- The top surface is drawn.

- Common tangents are drawn to the circles.

To draw an oblique image of an upright circular cylinder - do my math homework , the oblique image of the base surface must first be drawn. To simplify matters, the depth lines can be drawn at an angle of 90° (as opposed to 45° for the cavalier projection). The oblique image of a circle is called an ellipse.

To represent a standing prism in Cavalier projection, the oblique image of the base surface must first be drawn. If there are edges in the base that do not run in the depth direction, auxiliary lines must be drawn in the depth direction:

For the oblique image of a prism lying on its side, the base surface is drawn first. Then the depth lines are drawn at an angle of 45° and shortened by half - statistics homework help . Now the top surface is drawn in. The visible edges are drawn thicker and the invisible edges are drawn dashed.

Representation in the two-panel image

For two-panel images of prisms and circular cylinders, as many surfaces as possible should lie parallel to the ground plan or elevation plane.
