Creating a Subdivision Box

From the Subdivision section of the action bar, click Box

.

A box is displayed in the work area.

Select a plane or planar face for the subdivision.

Repeatedly press Tab to cycle through the orientation of the subdivision on the various planes.

Click in the work area to place the box in the approximate location you want.

Optional: From the work area, in the Freeform dialog box, do the following to adjust the end conditions of the feature:

Click Midplane to extend the feature equally in both directions from the sketch plane. This specifies overall length.
Select Flip to reverse the orientation of the feature and direction of the pull.
Drag the Scale slider to scale the size of the subdivision body. It is set to 100 by default.
Select Crease edges to crease the edges of the subdivision body so that it no longer has round corners.

Click in the text boxes and enter the number of subdivision in the mesh cage.

Drag the arrows to define the height and width.

Click

in the FreeForm dialog box.

Optional: Drag the Robot arrows to position the box.

Optional: Drag the mesh points and faces to customize the shape of the box.

To assist with selecting the mesh entities, the following options are available:

For faces, press i or o to select a face loop around the subdivision. Click near an edge of the face to select the direction of the loop.
For edges, press i to select edge rings around the subdivision, or press o to select edge loop around the subdivision.
