3D Faces
3DFACE creates a three or four sided surface anywhere in 3D space. You can specify different Z co-ordinates for each corner point of a 3D face. 3DFACE differes 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

3D Face Invisible Edge
With 3DFACE, You can control which edges of a 3D faces are visible, allowing accurate modelling 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 shape object just like below we shown.
2. Set the visibility style to conceptual
3. Type 3DFACE in 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: we must enter “i” for invisible before the face is chosen.
Edge Command
1. Type EDGE in the command prompt
Command: edge
Specify edge of 3Dface to toggle visibility or [Display]: Pick edge
Specify edge of 3Dface to toggle visibility or [Display]: D
Enter selection method for display of hidden edges [Select/All]: A
/** Regenerating 3D face objects ... Done. **/
Specify edge of 3Dface to toggle visibility or [Display]: Press ENTER
PFace
Creates a 3 dimensional polyface mesh vertex by vertex.
1. Type PFACE at the command prompt
Command: pface
Specify location for vertex 1: Pick point 1
Specify location for vertex 2 or <Define faces>: Pick point 2
Specify location for vertex 3 or <Define faces>: Pick point 3
Specify location for vertex 4 or <Define faces>: Pick point 4
Specify location for vertex 5 or <Define faces>: Pick point 5
Specify location for vertex 6 or <Define faces>: Pick point 6
Specify location for vertex 7 or <Define faces>: Pick point 7
Specify location for vertex 8 or <Define faces>: ENTER
