■ Create Custom Mesh (Legacy)
Creates a 3D polyface mesh vertex by vertex.
List of Prompts
The following prompts are displayed.
Specify
location for vertex on page 1462 1: Specify a point
Specify location for vertex 2 or <
define faces on page 1462>: 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
Vertex Number You define each face by entering vertex numbers for all the
vertices of that 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.
You can create polygons with any number of edges. PFACE automatically
breaks them into multiple face objects with the appropriate invisible edges.
Faces with one or two vertices behave like point or line objects without the
special properties of Point Display modes or linetypes. You can use them to
embed wireframe images within a mesh. Use Endpoint object snap to snap to
a face composed of one or two vertices. All object snap modes that apply to
line objects work with visible edges of polyface meshes. You cannot use PEDIT
to edit polyface meshes.
Color Faces created with PFACE adopt the current layer and color. Unlike
polyline vertices, polyface mesh faces can be created with layer and color
properties different from their parent object.
