Hidden lines.
Each line time is used to show different things. Some of the lines are, Center lines( long- and short-dashed lines.)cutting plane lines( thin, medium-dashed lines, or thick long- and double short-dashed) and section lines(thin lines in a pattern).
Dashed lines typically represent a range of concepts depending on the context in which they are used. In graphs or charts, they may indicate a trend, boundary, or threshold that is not solidly defined. In diagrams, dashed lines can signify a relationship or connection that is not direct or is conditional. Overall, they often convey a sense of uncertainty, approximation, or distinction from solid lines, which usually represent definite or established parameters.
To draw two water molecules with dashed lines to indicate hydrogen bonds forming between them, represent each water molecule as an oxygen atom (O) with two hydrogen atoms (H) bonded to it. Then, draw dashed lines connecting the oxygen atom of one water molecule to the hydrogen atoms of the other water molecule. These dashed lines represent hydrogen bonds forming between the two water molecules.
In electrical floor plans, dashed lines typically represent items that are not physically present in the current view but are relevant for understanding the layout. This can include elements such as hidden electrical wiring, circuits, or future installations. They help convey information about the overall electrical system without cluttering the main plan. Additionally, dashed lines can indicate relationships or connections between components that are not directly visible.
The Different drafting lines are the following:visible - are continuous lines used to depict edges directly visible from a particular angle.hidden - are short-dashed lines that may be used to represent edges that are not directly visible.center - are alternately long- and short-dashed lines that may be used to represent the axes of circular features.cutting plane - are thin, medium-dashed lines, or thick alternately long- and double short-dashed that may be used to define sections for section views.section - are thin lines in a pattern (pattern determined by the material being "cut" or "sectioned") used to indicate surfaces in section views resulting from "cutting." Section lines are commonly referred to as "cross-hatching."phantom - (not shown) are alternately long- and double short-dashed thin lines used to represent a feature or component that is not part of the specified part or assembly. E.g. billet ends that may be used for testing, or the machined product that is the focus of a tooling drawing.
On a topographic map dashed lines can represent boundaries (e.g. national, state, etc). A dashed line can also represent a hiking trail or a telephone, or above-ground oil or gas line.The color and length of the dashes can distinguish between one type and another. Check the map legend to understand the exact meaning.
Visible lines are lines that are drawn in a technical drawing to represent the edges or outlines of an object that can be seen in the finished product. Invisible lines, on the other hand, are used to represent features that are hidden from view or are behind other objects in the drawing.
The short dotted lines are the type of lines on a drawing that are designed to represent the hidden details.
Dashed yellow lines on the road indicate that passing is allowed when it is safe to do so.
The word that describes dashed lines in a polygon is "dashed." In geometric terms, dashed lines often indicate segments that are not solid or complete, representing boundaries, constraints, or areas that are not included. They can also signify certain conditions or properties in geometric diagrams, such as lines of symmetry or hidden edges in 3D representations.
these lines represent that the drawing is too large for he required space so the lines help the spectator to understand that the drawing is too big.
it means to rush
