What angle is a miter line drawn at?

45 degrees

What is a Miter line in Autocad?

The Miter Line and Projection Lines The use of a 45° miter line and Projection Lines provide a quick, accurate method of drawing the other views once one view is completed. Sometimes you will need to work on separate views and project lines to each other to fully complete any view.

What is the purpose of 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. Often they are omitted in an isometric view.

How do I find hidden lines?

Hidden lines are used to show surfaces that are not directly visible. All surfaces must be shown in all views. If an edge or surface is blocked from view by another feature, it is drawn using a hidden line. Figures 4-11 and 4-12 show objects that require hidden lines in their orthographic views.

What are alphabet lines?

Why is it important to recognize the alphabet of lines? The lines in the Alphabet of Lines are used to describe shape, size, hidden surfaces, interior detail, and alternate positions of parts. Each conveys a particular meaning on the drawing.

What are the 7 types of lines?

There are many types of lines: thick, thin, horizontal, vertical, zigzag, diagonal, curly, curved, spiral, etc.

What are the 4 types of lines?

In Geometry, there are basically four types of lines….They are:

Horizontal Lines.
Vertical Lines.
Parallel Lines.
Perpendicular Lines.

What are the five basic types of lines?

There are 5 main types of lines in art: vertical lines, horizontal lines, diagonal lines, zigzag lines, and curved lines. Other types of lines are simply variations of the five main ones.

What are three basic kinds of lines?

Types of Lines

Vertical lines: are straight up and down and perpendicular to horizontal lines.
Horizontal lines: are straight up and down and perpendicular to vertical lines.
Diagonal lines: are lines that straight in any direction except vertical or horizontal.

Arches. Arc-like curve.
Spirals. winding or circling around a central point.
Circle.

What is a straight line called?

A line is sometimes called a straight line or, more archaically, a right line (Casey 1893), to emphasize that it has no “wiggles” anywhere along its length. Two lines lying in the same plane that do not intersect one another are said to be parallel lines.

What is the heaviest line in a drawing?

The heaviest line weight indicates the ground line cut. The next heaviest line weight “profiles the planes closest to the plane of projection” (Ching & Juroszek, 1998, p. 152). Medium line weight indicates distance from picture plane, progressively getting lighter to describe objects further from the picture plane.

What is short break line?

Short break lines are thick, wavy solid lines that are drawn freehand. When either of these break lines is used to shorten an object, you can assume that the section removed from the part is identical to the portions shown on either side of the break.

What are visible lines?

Visible lines are the edges or “outlines” of an object. They are drawn as solid lines with a thick/heavy weight.

How line is being created?

A line is an identifiable path created by a point moving in space. Lines often define the edges of a form. Lines can be horizontal, vertical, or diagonal, straight or curved, thick or thin.

What are the different types of lines in drafting?

Using the Alphabet of Lines

Construction Line. This line is used mainly in sketching, which is a freehand drawing technique.
Visible Object line. This line is used to draw all the edges of the object.
Hidden Object Line.
Centre Line (or centreline)
Extension Line.
Dimension Line.

What is reference line?

A reference line, also referred to as a base line, is a user-defined vertical or horizontal line in the graph. Use reference lines to compare, reference, or measure against the data values displayed in the graph. Reference lines are available if the X or Y axis contains a metric.

How do you use reference lines?

To add a reference line:

Drag Reference Line from the Analytics pane into the view.
The Line option is already selected at the top of the dialog box.
Select a continuous field from the Value field to use as the basis for your reference line.
Select an aggregation.
Select how you want to label the line:

What is reference point?

A reference point is a place or object used for comparison to determine if something is in motion. An object is in motion if it changes position relative to a reference point. Objects that are fixed relative to Earth – such as a building, a tree, or a sign – make good reference points.

What is reference line in EG?

: an arbitrary fixed line (as an x-axis or a polar axis) from which coordinates of a point are computed.

What is a plane scale?

Plane scale (Naut) a scale for the use of navigators, on which are graduated chords, sines, tangents, secants, rhumbs, geographical miles, etc.

What is principal plane projection?

The plane, horizontal or vertical, which are kept perpendicular to each other are called Principal Planes. 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 is reference line XY?

2.1.6 Main Reference Line, x-y. The line of intersection of Horizontal plane (HP) and Vertical plane (VP) is the main. reference line, x-y (refer Figure 2.1). The lines of intersection of auxiliary planes with principal planes are auxiliary. reference lines.

What is XY line in engineering drawing?

line of intersection of HP and VP is denoted as XY. line, XY, to represent the line of intersection of HP and VP.

What is VP and HP?

VP: The plane in front of observer is the vertical plane. HP: The plane which is Horizontal and perpendicular to VP is Horizontal Plane. Top View (TV): The projection on the HP is called the Top View (TV) or Horizontal Projection or Plan. Note: The planes HP and VP are called Principal Planes.

When a point is above HP and behind VP The point is resting in?

Answer. Explanation: The position of reference planes will be similar to quadrants in x, y plane co-ordinate system. As the 2nd quadrant lies above the x-axis and behind the y-axis here also the 2nd quadrant is above H.P, behind V.P.
