Where do you put 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 does a phantom line do?
Phantom lines indicate the alternate position of parts of the object or the relative position of a missing part. Phantom lines are composed of one long and two short evenly spaced dashes. Sectioning lines indicate the exposed surfaces of an object in sectional view.
How are hidden lines represented on a drawing?
It is standard practice to use dashes to represent any line of an object that is hidden from view.
What is double dimensioning?
4.5/5 (66 Views . 14 Votes) Dual dimensioning is the drafting practice of using multiple units of measure in a dimension in the same direction of a feature. SolidWorks and many other CAD programs support dual dimensioning.
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 are 5 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.
Which construction drawings shows property lines?

What are leader lines?
A leader line is a line that establishes a connection between a graphical representation of an item and some text. A leader points to a bit of our drawing and says: ‘Oi – Look Here’ and ‘Read This! ‘.
What is the purpose of hidden lines and centerlines?
Hidden lines show edges of details that are not visible from the point of view shown in the drawing. Center lines define the center of arcs, circles, or symmetrical parts.
Can you dimension hidden lines?
Dimensioning to hidden lines should be avoided wherever possible. Use auxiliary cross sectional views instead. … Longer dimensions should be placed outside all intermediate dimensions so that dimension lines will not cross extension lines.
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 is the meaning of hidden line?
[′hid·ən ′līn] (graphic arts) For a three-dimensional object, a line that cannot be seen because view of it is obstructed by part of the object or of another object.
Do you draw hidden lines in isometric drawings?
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. … In general, use centerlines sparingly in isometric drawings.
What are the 8 rules of dimensioning?
Terms in this set (8)Rule 1: Dimensions should not be duplicated, nor should the same info be given in two different ways.Rule 2: Dimensions should be attached to the view that best shows the contour of the feature being dimensioned.Rule 3: … Rule 4: … Rule 5: … Rule 6: … Rule 7: … Rule 8:
What is the difference between a size dimension and a location dimension?
Size dimensions describe the size of each geometric feature. … Location dimensions show the location of each geometric feature within an object or view. Location dimensions tell the viewer where edges occur inside an object view.
What is a hidden line in architecture?
Hidden lines are used to show the concealed edges of an object or a completely hidden object, like for example the foundation of a building or a structure covered by earth. Of course, only the most important features are shown by hidden lines, otherwise the drawing would be cluttered.
Which type of line is used for showing invisible parts?
Phantom linesPhantom lines are used to indicate imaginary features such as alternate positions of moving parts and adjacent positions of related parts.
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 do phantom lines look like?
Center Line: Centerlines consist of alternating long and short evenly spaced dashes, with a long dash at each end and short dashes at point of intersection. Phantom Lines: Phantom lines are thin lines used to indicate alternate position of the parts of an object, repeated detail, or the location of absent parts.
