When the Vertex subobject mode is selected, these vertex commands become available.

Collapse
The Collapse button is used to collapse all the selected subobjects to a single subobject located at the aver-
aged center of the selection. This button is similar to the Weld button, except that the selected vertices don’t
need to be within a Threshold value to be combined. This button works in all subobject modes.
Detach
Use the Detach button to separate the selected subobjects from the rest of the object. To use this button,
select the subobject and click the Detach button. The Detach dialog box opens, enabling you to name the
new detached subobject. You also have the options to Detach to Element or to Detach as Clone. All subob-
ject modes except Edge have a Detach option.

Extrude
The Extrude button copies and moves the selected subobject perpendicular a given distance and connects
the new copy with the original one. For example, four edges forming a square extruded would form a box
with no lid. To use this feature, select an edge or edges, click the Extrude button, and then drag in a view-
port. The edges interactively show the extrude depth. Release the button when you’ve reached the desired
distance.
Alternatively, you can set an extrude depth in the Extrusion spinner in the caddy. The Group option
extrudes all selected edges in the direction of the average of all the normals for the group (the normal runs
perpendicular to the face), and the Normal Local option moves each individual edge along its local normal.
For polygons, you can extrude By Polygons, which extrudes each individual polygon along its normal as a
separate extrusion. To exit Extrude mode, click the Extrude button again or right-click in the viewport.
The Extrude button is enabled for Face, Polygon, and Element subobject modes for the Editable Poly
object. The Local Normal option extrudes each edge along its own normal.
The Extrude settings caddy includes options for setting the Extrusion Height and the Extrusion Base Width.

Remove
The Remove button lets you delete the selected vertices. The Remove button automatically adjusts the sur-
rounding subobjects to maintain the mesh integrity.

Note
You can also delete Editable Poly subobjects using the Delete key. n
The Remove button also is available in Edge subobject mode. If you hold down the Ctrl key when clicking
the Remove button when an edge is selected, vertices at either end of the deleted edge are also removed.
