closed N direction
Nopen
Opens the N-direction polylines if the polygon mesh is closed in the N
direction.
Undo
Reverses operations as far back as the beginning of the PEDIT session.
PFACE
Creates a three-dimensional polyface mesh vertex by vertex
Command line: pface
Specify Vertex Location 1: Specify a point
Specify location for vertex 2 or <Define Faces>: Specify a point or press ENTER
Specify location for vertex n or <define faces>: Specify a point or press ENTER
Vertex Location
You specify all vertices used in the mesh. The vertex numbers displayed in
the prompts are the numbers used to reference each vertex. The prompt is
repeated until you press ENTER . If you press ENTER on a blank line, you
are prompted for the vertices to be assigned to each face.
Define Faces
Enter a vertex number or [Color/Layer]: Enter a vertex number or enter an option
Vertex Number
You define each face by entering vertex numbers for all the vertices of that
face. Pressing ENTER after the prompt causes the program to prompt for
the vertex numbers of the next face. The mesh is drawn after you have
defined the last face and pressed ENTER after the prompt.
To make an edge invisible, you can enter a negative vertex number for the
beginning vertex of the edge. The SPLFRAME system variable controls the
display of invisible edges in polyface meshes. Setting SPLFRAME to a
non-zero value displays any phantom faces and all invisible edges of polyface
