Creating a Hidden Line Projection
Use this procedure to create a 2D graphic from a 3D view of one or more objects in your drawing. The 2D graphic that you create is a flattened representation of the objects in the current 3D view, with hidden background lines. Use the Hidden Line Projection command to create quick 2D elevations and sections.
After you create an elevation or section hidden line projection, you can hatch or shade the cut areas. You can also use hidden line projections to create detail drawings. For more information about creating elevations and sections, see and .
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. You can edit or explode the inserted block. If you want to insert the block in another drawing as a named block, define the block. For more information about inserting blocks, see “Insert Blocks” in AutoCAD help.
- Open the tool palette that you want to use, and select a hidden line projection tool.
- In a 3D view select one or more objects that you want to use to create your hidden line projection, and press ENTER.
- Specify an insertion point in your current drawing for the 2D hidden line projection.
- Specify the insertion point for the 2D hidden line projection into your drawing:
