Center Commands

Modo offers a number of centering commands that allow you to quickly center a geometry selection at the World Origin (0,0,0) position. The commands can be found in the modeling tabs under the Basic sub-tab - Center Selected. Clicking the menu button provides a pop-up with options that constrain to specific axes, or All. The commands can also be invoked from the menu bar Edit > Center Selected. There is no dialog box or user-specified setting for these commands.

The behavior of Center depends on the selected data and the command arguments used. If a single vertex is selected, center moves the vertex to position 0 for the defined axis (or axes). When an edge is selected the center point of the edge is placed at the centered axis (or axes). With a polygon selected, the polygon is moved so that the center of the polygon rests at the center of the defined axis (or axes). When there are more than one vertex, edge, or polygon selected, the center of the bounding volume of that selection is placed at the center of the defined axis (or axes).

The Center commands are meant to work on component selections. Should you wish to center an item while in Item mode, they should use the Reset function available in the items properties, returning that item layers center to the World Origin. You should note that this only centers the item itself, and does not modify the geometry within the item layer.

Warning:  If you apply the Center commands to a Mesh Item that already has a transformation applied, it is recommended that you also apply the freeze option in the item's properties panel, returning its center to the World Origin. If you don't, strange behavior may occur.
