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.
People ask also, what is a hidden line? 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. Sometimes they are used to make a drawing easier to understand. Often they are omitted in an isometric view. Section Line.
Moreover, what is a hidden line 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.
Amazingly, what are hidden object lines used for? 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.
Also know, what is the difference between a hidden line and a center line? In a scaled drawing, the hidden line can be measured from the start of the first dash, to the end of the last dash. Centre lines are drawn to indicate the exact centre of a component being drawn. They are made from a series of lighter long and short dashes.A hidden line projection tool is located with the Helper Tools in the Stock Tool Catalog. Alternatively, you can click Home tab Section & Elevation panel Hidden Line Projection. In a 3D view select one or more objects that you want to use to create your hidden line projection, and press Enter.
Hidden lines: indicate areas or objects not visible on the surface, or objects hidden behind others. They are also used to show objects above the cutting plane of a floor plan, such as wall cabinets, beams, arches, etc.
It is standard practice to use dashes to represent any line of an object that is hidden from view.

What are the 6 types of lines?
- Horizontal Lines.
- Vertical Lines.
- Parallel Lines.
- Perpendicular Lines.
- Some other lines.
Hidden lines can show something that would not be otherwise visible on the drawings. For example, hidden lines may show the length of an internal step in a turned part without using a section or a cutout view (we explain both later). Centre lines are used to show hole and the symmetric properties of parts.
What is the visible line?
Also called “object” lines, visible lines denote physical features that are visible in the view in which they appear. For instance, a cylinder shown below is shown in two views.
What are the 12 types of lines?
- Object lines. shows the contour or outline of objects.
- Hidden lines. represents features that are hidden in current view.
- Centerlines. locates the center of circles and arcs.
- Extension lines. show the extinct of a dimension.
- Dimension lines.
- Leader lines.
- Cutting-plane lines.
- Viewing-plane lanes.
Right-click the drawing view and select Properties. Select the Show Hidden Edges tab. Select a feature or component from either the drawing view or the FeatureManager design tree to add it to the list of items to be shown with hidden lines.
- Select the layout viewport in which you want to hide the lines.
- Click View tab Palettes panel Properties palette.
- On the Properties palette, under Misc, in the Shade Plot field, select Legacy Hidden.
How many types of lines are there in AutoCAD?
The AutoCAD software package comes with a library of standard linetypes that has 38 different standard linetypes. Linetypes can be a pattern of dashes, dots, text, and symbols or unbroken and continuous.
