What is hidden detail in engineering drawing?
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.
How can I see engineering drawings?
The title block contains information such as:
- Name and address of the company or agency who prepared or owns the drawing.
- Part number and description.
- Material.
- Mass.
- Finish.
- General tolerances.
- Projection details.
- Scale used in the drawing.
How do you show hidden details in a drawing?
Solution:
- Right-click the view.
- Click in the drop-down menu Edit View…
- In the dialog box Drawing View click on the Hidden Line button.
- If you see this icon. , it means that you have activated the checkbox on Style above the buttons.
- After clicking the OK button, you should see the hidden lines, in the view(s).
What does a hidden line look like?
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.
What are hidden lines engineering?
It is standard practice to use dashes to represent any line of an object that is hidden from view. The number of hidden lines in a view of a complicated object may be very great. …
Do isometric drawings show hidden lines?
Usually only the visible surfaces of an object are drawn in isometric, with hidden lines left out. Although this is considered the preferred practice, there are always times when hidden lines are needed to clarify very complex isometric drawings.
What are the three types of engineering drawings?
Listed are detail drawings, assembly drawings, schematic drawings, and many other content specific drawing types.
What type of lines are used for hidden details?
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 three hidden views of isometric drawing?
You may be wondering about the three views that are hidden. They are called the Bottom View, the Left Side View, and the Rear View. Can you determine where they go? The next drawing shows the relationship of isometric surfaces to the views in orthographic drawings.
What are hidden lines on an engineering drawing?
The line thickness varies – the outer contour uses thicker lines and inner lines are thinner. Hidden lines can show something that would not be otherwise visible on the drawings.
Which is the best way to draw an engineering object?
Any engineering drawing should show everything: a complete understanding of the object should be possible from the drawing. If the isometric drawing can show all details and all dimensions on one drawing, it is ideal. One can pack a great deal of information into an isometric drawing.
When to use plan view and elevation view drawings?
The type of drawings most commonly used on job sites are plan and elevation views. Usually the plan and one elevation view are used to fully describe an object, however in some instances more than one elevation view is needed. Explain. The plan view is the view as seen from above the ob- ject, looldng down on it or the top view.
How are broken lines used in three view drawings?
In a three-view drawing, solid limes are used to rep- resent the details of an object which can be seen in each view. Broken lines are used to illustrate the openings which are “hidden” in the Front and Right-Side Views. See Fig. 2-7. rnnrr-vrrw, 1-LAN VlLW AND ELEVATION VIEW DRAWINGS 3 TOP View The Front View, Top View, and the Right-

When to use break lines in engineering drawing?
The dimension line has two arrowheads between the extension lines and the measurement on top (or inside, like in the image above) the line. Break lines indicate that a view has been broken. If you have a part that is 3000 mm long and 10 mm wide with symmetric properties, using a break-out makes gives all the info without using as much space.
What are the different types of engineering drawings?
Engineering drawings (also sometimes known as blueprints, manufacturing blueprints, prints, manufacturing prints, dimensional prints, drawings, mechanical drawings, and more) are a rich and specific outline that shows all the information and requirements needed to manufacture an item or product.
