# Create user axes
The Create user axes dialog box is used to create a user axis set which may either overwrite an existing axis set or become a new one.
Some nodes or grid points must be selected prior to opening this dialog box. These nodes or grid points are used to define the origin, x vector and xy vector of the axis set. The xy vector need only be defined for space structures so three nodes or grid points must be selected for space structures; otherwise two.
Open this dialog box by giving the Sculpt > Create user axes menu command or from the Sculpt toolbar when the current view is a Graphic view.
# New axis set: Overwrite set
- New axis set – The defined axis set will be appended to the current module of user axis sets.
- Overwrite set – The defined axis set will overwrite the existing set specified here.
# Name
The name of this axis set.
# Type
Whether the axis set is Cartesian, cylindrical or spherical.
# Axes definition
Use the spin control to select the required axes from the various axes that can be defined by the selected nodes or grid points. The origin, x vector and xy vector identified by the current selection are displayed in the dialog box and the axes are displayed on the Graphic View.
