Append
Modify > Append
 

Description:

    The Append (Modify > Append) submenu contains tools for appending new polygons or lines to the existing object.

    Appen Polygon From Vertices will create a polygon from three or more selected vertices.  Note that it does matter which order you select the vertices in: they must be selected in the order that they will appear along the new face's border.

    The Append Polygon Tool allows you to interactively choose or create vertices for a new polygon. The first vertex chosen must be an existing vertex on the object. After that, you can either select another vertex on the mesh or click somewhere else to create a new vertex. (Silo will endeavour to create this new vertex in the plane of those already created or chosen.) Press Enter once or right-click to create the polygon. The tool will remain active upon pressing Enter, should you wish to create another polygon. Otherwise, press Enter again to exit the tool.

    Append Line From Vertices will create edges between the selected vertices, in the same order they were selected.  Note that if you select two vertices on opposite sides of a face and call this command, it will not split the face into two faces, but will instead add a new edge across the middle of the face.  To properly split a face, use the Connect command or the Split Tool.

    The Append Line Tool behaves much like the Append Polygon Tool. Again the first vertex must be on the object, but subsequent vertices may be chosen from those already on the object, or you may left-click where there isn't already a vertex to create a new vertex.


Notes:

-Only one object may be selected in order to use the Append Polygon and Append Line tools. You may have to switch into object selection mode and deselect other objects in the scene. This restriction does not apply to Append Polygon From Vertices or Append Line From Vertices, although these operations also cannot be performed on vertices from two or more different objects.

-The normal vector of a face created with the Append Polygon From Vertices command will be deternined based on the normal vectors of neighboring faces. It can be reversed with the Reverse Normals (Modify > Reverse Normals) command.
