# Projections of Cylinder

### Sample Problem 1:Draw the projections of a cylinder, base 30 mm diameter and axis 40 mm long , resting with a point of its base circle on HP such that the axis is making an angle of 30º with HP and parallel to VP.

Steps for Projections of Cylinder:

1. Simple Position:

Assume the cylinder , resting with its base on HP and axis perpendicular to it. Draw top view first and then the corresponding front view.

2. Second Position:

Cylinder has to rest with a point if its base circle on HP such that its axis has to make θ=30º with HP.hence tilt the front view such that 3′ is on XY and base is at 60º (i.e., 90º-θ) to XY. thus obtain the second front view with the axis inclined at 30º to XY..

Project the corresponding second top view , in which the axis is parallel to XY.

JOin the ellipse by common tangents in the second top view. Draw dashed line for half of the ellipse for the hidden base.
