Projections of line

In first angle projection, the projection of a line involves creating 2D representations of the line from different viewpoints: the front, top, and side. This projection technique helps to visualize the true shape and position of the line relative to the principal planes of projection. 

Projection Planes:

• Front View Plane (Vertical Plane): Shows the projection of the line as seen from the front.

• Top View Plane (Horizontal Plane): Displays the projection of the line from above.

• Side View Plane (Profile Plane): Shows the projection of the line from the side.

Projection Process:

• Front View Projection:

  • Project the line onto the vertical plane by ignoring the yyy-coordinates.

  • This view shows the height and depth of the line segment.

• Top View Projection:

  • Project the line onto the horizontal plane by ignoring the zzz-coordinates.

  • This view shows the width and depth of the line segment.

• Side View Projection:

  • Project the line onto the profile plane by ignoring the xxx-coordinates.

  • This view shows the height and width of the line segment.

Arrangement of Views:

• Front View: Positioned on the vertical plane (left side of the drawing).

• Top View: Positioned below the front view.

• Side View: Positioned to the right of the front view.
