What type of lines are used for hidden details?
Hidden line Hidden details are shown by a series of dashes making up a broken line.
It is normal practice that you place a dash at the beginning of the hidden line and another at the end where it meets an intersecting line..
How do I find hidden lines in an object?
A drafter—in deciding whether a line in a view should be represented as hidden or as visible—relies on the fact that in third-angle projection the near side of the object is near the adjacent view, but in first-angle projection the near side of the object is remote from the adjacent view.
What are the 7 types of lines?
There are many types of lines: thick, thin, horizontal, vertical, zigzag, diagonal, curly, curved, spiral, etc. and are often very expressive.
What are the two major methods of dimensioning?
The basic types of dimensioning are linear, radial, angular, ordinate, and arc length. Use the DIM command to create dimensions automatically according to the object type that you want to dimension.
What does a hidden line look like?
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. … The hidden portion of the line is drawn using a hidden-line pattern, and the visible portion of the line is drawn using a solid line.
Which type of lines are used to represent hidden edges?
Figure 5: Use of dashed lines to represent edges hidden in views of a complicated object.
How do you show hidden lines in paper space?
Show Hidden Lines in the Current ViewportSelect the viewport in which you want to show hidden lines.Click View tab Palettes panel Properties palette.On the Properties palette, under Misc, in the Shade Plot field, select As Displayed.
What does a hidden lines represent in drawing?
Hidden lines in a drawing represent the edges where surfaces meet but are not directly visible. Hidden lines are omitted from pictorial drawings unless they are needed to make the drawing clear. Figure 3.46 shows a case in which hidden lines are needed because a projecting part cannot be clearly shown without them.
What does a Dimension line look like?
The dimension line is a thin line, broken in the middle to allow the placement of the dimension value, with arrowheads at each end (see diagram below). An arrowhead is approximately 3 mm long and 1mm wide. That is, the length is roughly three times the width.
What are alphabet lines?
The Alphabet of Lines is a list of line symbols that engineers use in technical drawings to communicate specific shapes, sizes or surfaces. In the Alphabet of Lines, thick, dark lines represent the outline of an object, showing its visible surfaces and edges.
What is Lines and its types?
A line is a one-dimensional figure, which has length but no width. … The two points which lie on the same line are said to be collinear points. In geometry, there are different types of lines such as horizontal and vertical lines, parallel and perpendicular lines.
How do you hide a viewport line?

How do I make lines invisible in AutoCAD?
To Make Hidden Lines InvisibleAt the Command prompt, enter AM2DHIDE.Select the elements representing the foreground . The blue plate with the hole is the foreground. The Hide Situation dialog box appears.In the background tab select Invisible on Layer AM_9.
How do you use hidden lines?
Hidden lines are dashed lines used to represent internal features that are obscured by the object. These hidden lines represent the obscured corner of the notch. potential hidden lines in this sketch fall directly behind visible lines in the right side view.
What four lines are used to aid in dimensioning?
There are four methods: parallel, running, chain, and combined dimensioning. Some methods of dimensioning a drawing can create an accumulating error.
What is long break line?
Long break lines are thin solid lines that have zigzags to indicate a break. Short break lines are thick, wavy solid lines that are drawn freehand.
What are hidden lines in Autocad?
When you create hidden line projections, the 3D objects that you select are copied and collected into an unnamed (also called anonymous) 2D block. The unnamed block can be placed in your drawing in the current 3D view, or placed parallel to the XY plane to be viewed in plan view.
Which lines on a drawing should be the thickest?
Here, the typical rule is the closer the object, the darker the line; the further away, the lighter the line. This is because read thicker, heavier lines as being closest to us, whereas lighter lines recede into the background.
