1a : strong hard-laid line that is used to form the main line of a setline and is usually provided in bundles of 300 fathoms weighing 48, 40, or sometimes 32 pounds. b : the main line of a setline consisting of one or more bundles of groundline.
What is ground plane in perspective drawing?
: the horizontal plane of projection in perspective drawing.
What are the 3 parts of a picture plane?
In the technique of graphical perspective the picture plane has several features: Given are an eye point O (from oculus), a horizontal plane of reference called the ground plane γ and a picture plane π…
What is a false ground line?
With a false ground, the frame becomes connected to the neutral instead, and any connection of the frame to a grounded object will result in current flow. If that connection is a person, there is the possibility of a fatal shock.
What is a ground line in architecture?
Noun. groundline (plural groundlines) (art) A line drawn to signify the surface of the ground, especially in architectural blueprints and in drawings by children which lack dimension.
What is line projection?
Projection lines are extensions of lines that assist in 2D drawing. … For example, in a drawing, you can use projection lines on an auxiliary view to enable creation of additional views with proper alignment and size.
What are the orthogonal lines?
Orthogonal lines are parallel to the ground plane and move back from the picture plane. Orthogonal lines set the varying heights or widths of a rectangular plane as it recedes from view. Orthogonal lines always appear to meet at a vanishing point on the eye level.
What is ground line quizlet?
Ground line. a base line upon which figures stand. Hierarchy of scale. a system of representation that expresses a persons importance by the size of his or her representations in a work of art.
What are the 3 planes of projection?
These include the Frontal Plane, Profile Plane, and Horizontal Plane: In addition to this, if a plane is placed at any other place, then it is called Auxiliary Plane.
What are the types of projection?
There are two main types of projection:
- A. Parallel and Orthographic.
- Station-point and Perspective.
- Parallel and Convergent.
- Perspective and Parallel.
What is a hidden line?
A hidden line, also known as a hidden object line is a medium weight line, made of short dashes about 1/8” long with 1/16”gaps, to show edges, surfaces and corners which cannot be seen. Sometimes they are used to make a drawing easier to understand.
What does line of sight refer to?
1 : a line from an observer’s eye to a distant point. 2 : the line between two points specifically : the straight path between a transmitting antenna (as for radio or television signals) and a receiving antenna when unobstructed by the horizon.
What is Station Point art?
: the position of an observer that determines the perspective rendering of the objects or scene being represented in a drawing — compare linear perspective.
What are the differences between one point and two point perspective?
What is the difference between one point perspective and two point perspective? In one point perspective, all the lines that are not vertical or horizontal vanish into one point in the image. … In two point perspective, all non-vertical lines vanish into two points of the same height at the border of the image.
How can you tell false ground?
A false ground or bootleg ground involves using a jumper wire to connect the ground screw and the neutral screw on a receptacle. This is done to trick the hand held testers most inspectors use to check for open grounds. This is a common trick used by misinformed do-it-yourselfers and some clueless handy men.
How can you tell if you have a bootleg ground?
To find out if you have a bootleg ground, turn off the electric at the panel box. Remove the receptacle cover and see if there is a jumper wire. If you are not sure, pull the receptacle out of the wall to check. Also, check that the white wires go to the white metal screws.
What is the plane of the ground?
(in perspective drawing) the theoretical horizontal plane receding from the picture plane to the horizon, beginning at the level of the base line.
What is a picture plane in drawing?
When an artist creates an impression of space within a painting the picture plane is the transparent division between this fictive internal space and the real space outside, in which the viewer is placed.
What is a plane in a drawing?
: the surface of a picture drawn in linear perspective regarded as a transparent plane perpendicular to the lines of sight on which the points of objects in the scene may be considered as projected by straight lines drawn from these points to the eye.
What are the 2 types of projection?
Projection are defined as mapping of three-dimensional points to a two-dimensional plane. There are two type of projection parallel and perspective.
Which are the two main types of projection?
The most common types are the perspective and orthographic projections. The CAMERA_TYPE should be the first item in a camera statement.
