PFACE
 
 
 

Creates a 3D polyface mesh vertex by vertex.

 Command entry: pface

Specify location for vertex 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 meshes, which you can edit in the same manner as fully visible polyface meshes.

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.

New color [Truecolor/COlorbook] <BYLAYER>:Enter a standard color name or a color number from 1 through 255, enter t, enter co, or press ENTER

You can enter a color from the AutoCAD Color Index (a color name or number), a true color, or a color from a color book.

You return to the previous prompt.

Layer

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. Layer visibility behaves normally on faces of a polyface mesh. However, if you create a polyface mesh on a frozen layer, the program does not generate any of its faces, including those on non-frozen layers.

Enter a layer name <0>: Enter a name or press ENTER

You return to the previous prompt.
