The line will appear TL in
one view
since it is parallel to one of the projection planes.
When a line is inclined to one plane and parallel to the other its projection on the plane to which it is inclined?
When the line is inclined to one plane and parallel to the other, the
trace of the line is obtained
only on the plane to which it is inclined, and no trace is obtained on the plane to which it is parallel.
When the projection are parallel to each other and also perpendicular to the plane the projection is called?
Explanation: In
orthographic projection
, the projectors are parallel to each other and also perpendicular to the plane but in oblique projection, the projectors are inclined to the plane of projection and projectors are parallel to each other. … Explanation: Oblique projection is one method of pictorial projection.
When a line is inclined to VP and parallel to HP the front view will be to XY ?
If a line is parallel to H.P., its front will be to
XY line
. 12. If a line is parallel to V.P., its top view will be to XY line. 13.
What do you call the plane parallel to your projection?
A parallel projection (
or axonometric projection
) is a projection of an object in three-dimensional space onto a fixed plane, known as the projection plane or image plane, where the rays, known as lines of sight or projection lines, are parallel to each other.
What is the position of point in third quadrant?
When point is in 3rd quadrant, its plan will be
above XY
and elevation will be below XY.
When a line is inclined to both HP and VP its front view will be?
Explanation: Since the line is parallel to both HP and VP, both the front view a’b’ and the top view ab are
in true lengths
. Since the line is perpendicular to the right PP, the left side view of the line will be a point a ́ ́(b ́ ́).
Which lines on a drawing should be the thickest?
The
direction of the cutting line
is shown with a line called a cutting plane lineHeavy dashed line that shows a theoretical cut through an object.. This is the thickest line that may appear on a drawing.
Which projection satisfy the following condition projection lines are perpendicular to the view plane?
Orthographic projection, common method of representing three-dimensional objects, usually by three two-dimensional drawings in each of which the object is viewed along parallel lines that are perpendicular to the plane of the drawing.
When the line is inclined to VP and parallel to HP we get its true length in?
The projected length on the plane to which it is inclined will always be shorter than the true length. A line is parallel to H.P. and inclined to V.P., its true length will be seen in
H.P. i.e. top view
.
When the line is perpendicular to HP its front view appears as?
| S. No. Orientation/Position of line Front view or elevation | 1. Line parallel to both H.P. and V.P. True length, parallel to xy | 2. Line perpendicular to H.P. True length, perpendicular to xy | 3. Line perpendicular to V.P. Point | 4. Line inclined at θ to H.P. and parallel to V.P. True length, inclined at θ to xy |
|---|
When a plane surface is inclined to both HP and VP both its front view and top view will be?
3. Surface of plane is
perpendicular
to both H.P. and V.P. (i.e., parallel to profile plane).
When a point is above HP and in front of VP The point is resting in which quadrant?
Explanation: The position of reference planes will be similar to quadrants in x, y plane co-ordinate system. As the
1st quadrant
lies above the x-axis and in front of the y-axis here also the 1st quadrant is above H.P, in front of V.P.
Which projection gives a realistic view?
A perspective projection
produces realistic appearance, but does not preserve relative proportions. Points on the viewing plane (z=0) do not change.
Which is not true for Parallel projection?
What is not true for parallel projection?
Parallel projection rays are not perpendicular to the viewing plane
. Parallel lines in space appear parallel on the final projected image. Used exclusively for pictorial purposes rather than formal working drawings.
What are the 3 planes of projection?
These are
Top View, Front View, and Side View
. If the plane is kept in a vertical position, then it is called the vertical plane. If the plane is kept in a horizontal position, then it is called the horizontal plane.
