3D Faces in AutoCAD 3D – Part 1

3D Faces

3DFACE creates a three or four sided surface anywhere in 3D space. You can specify different Z coordinates for each corner point of a 3D face. 3DFACE differs from SOLID, which creates a three- or four-sided surface that is parallel to the current UCS and can be extruded.

1.    Begin     a new drawing.

2.  Set    the visual style to Conceptual.

3.  Type    

3DFACE at the command prompt.
Command: 3DFACE
First point: pick
Second point: pick
Third point: pick
Fourth point: pick
Third point: enter

2D Solids and 3D Faces AutoCAD 3D Part 1-13D Face Invisible Edge

With 3DFACE, you control which edges of a 3D face are visible, allowing accurate modeling of objects with holes. Entering i or invisible before the first point of an edge makes the edge invisible. Type 3DFACE at the command prompt.

1.  Draw    an irregular shaped object similar to the one shown below.

2.  Set    the visual style to Conceptual.

3.  Type     3DFACE at the command prompt.

Command: 3DFACE
First point: P1
Second point: P2
Third point: i P3
Fourth point: P4
Third point: i P5
Fourth point: P6
Third point: P7
Fourth point: P8
Third point: enter

NOTE:  You must enter an “i” for invisible before the face is chosen.
