Hidden Line Projection
You can create flat 2D projections with hidden background lines from a 3D view of objects in your drawing. The Hidden
Line Projection command produces quick sections and elevations of objects in your drawings that are not updated
automatically when you make changes to your 3D model.
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
“
Working With Elevations
” on page 1806 and “
Sections
” on page 1766.
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.
TIP The quickest way to locate and view an AutoCAD topic is to click the Search tab in the Help window, select the Search
titles only option, and then copy and paste or type in the AutoCAD topic name, and click List Topics.
NOTE Your 2D hidden line projections are not dynamically linked to the objects in the 3D view. Therefore, if you edit the
original object or objects in 3D view, the 2D graphic does not change. You must edit or re-create the 2D hidden line projection
to reflect any changes that you make to the original objects.
1
Open the tool palette that you want to use, and select a hidden line projection tool.
A hidden line projection tool is located with the Helper Tools in the Stock Tool Catalog. For more
information, see “
Understanding the Content Browser
” on page 80.
2
In a 3D view select one or more objects that you want to use to create your hidden line projection, and
press
ENTER
.
3
Specify an insertion point in your current drawing for the 2D hidden line projection.
4
Specify the insertion point for the 2D hidden line projection into your drawing:
■
Press
ENTER
to insert the 2D block in plan view.
■
Enter n (No) to insert the 2D block in the current view.
