1. Open the tool palette that you want to use, and select a hidden line projection tool.
2. In a 3D view select one or more objects that you want to use to create your hidden line projection, and press Enter.

Best answer for this question, how do you make a projection line?

Frequent question, what is the purpose of a projection line? Projection lines are extensions of lines that assist in 2D drawing. You can use projection lines to help you create new geometry, and any constraints you create with them remain active even after you turn projection lines off.

Correspondingly, how do you draw an orthographic projection in AutoCAD?

1. In the Browser, right-click the Base view icon, and then choose New View.
2. In the Create Drawing View dialog box, select the view type Ortho, and choose OK.
3. Select a location for the orthographic view directly below the base view, and then press ENTER.

Furthermore, how do you draw different views of an object in AutoCAD?

1. Click Drawing View Creation tab Select panel Model Space Selection. Find.
2. SHIFT-click the objects you don’t want to include in the base view. Tip: If you accidently removed an object that you didn’t intend to, click the object.
3. Press ENTER to return to the layout.

Explanation: Thick-thin-thick are used for cutting planes, dashed thick (wide) is used for surface treatment, zigzag lines are used for long-break lines and continuous thin line is used for dimensions, extensions and projection lines.

What is Projector line in engineering drawing?

The figure or view formed by joining, in correct sequence, the points at which these lines meet the plane is called the Projection of the object. The lines or rays drawn from the object to the plane are called Projectors. The transparent plane on which the projections are drawn is known as Plane of Projection.

What are the types of projection?

1. A. Parallel and Orthographic.
2. Station-point and Perspective.
3. Parallel and Convergent.
4. Perspective and Parallel.

Why do you need to draw projection lines when making an orthographic projection drawing?

Projection lines have been included to emphasize the importance of correct view location. Information is projected between the front and top views using vertical lines and between the front and side views using horizontal lines.

What are the 3 planes of projection?

Figure 5-4 shows the three principal (or primary) planes of projection, known as the VERTICAL, HORIZONTAL, and PROFILE PLANES. The angles formed between the horizontal and the vertical planes are called the FIRST, SECOND, THIRD, and FOURTH ANGLES, as indicated in the figure.

How do I draw an isometric projection in AutoCAD?

At first, you need to change your snap settings to isometric. Type DS on the command line and press enter. Drafting settings window will pop up from this window select snap and grid tab and make sure Isometric snap radio button is checked. Click OK to exit drafting settings window.

How do you do 3rd angle projection in AutoCAD?

1. Click Layout tab Styles and Standards panel Dialog box launcher. Find.
2. In the Drafting Standards dialog box, in the Projection type section, click the desired projection angle.

What is isometric projection in AutoCAD?

An AutoCAD isometric drawing is a 2 dimensional drawing just like a paper drawing. AutoCAD provides some tools to aid us in creating the drawing, but not very many. Mostly, we will be using the same commands that we used in creating orthographic drawings. We are going to draw the figure shown on the right.

How do you draw an orthographic projection?

1. Choose a front view.
2. Decide how many views are needed to completely describe the object.
3. Draw the visible features of the front view.
4. Draw projectors off of the front view horizontally and vertically in order to create the boundaries for the top and right side views.

What is first angle projection in AutoCAD?

1. First Angle Projection : In the first angle projection, the object is placed in the 1st quadrant. The object is positioned at the front of a vertical plane and top of the horizontal plane.

What is the difference between orthographic projection and isometric projection?

Isometric: a method of representing three-dimensional objects on a flat surface by means of a drawing that shows three planes of the object. Orthographic: a method for representing a three-dimensional object by means of several views from various planes.
