The figure below shows an example of creating a datum plane by rotating an
existing face through a specified angle.
From the main menu bar, selectToolsDatum.
The Create Datum dialog box appears. The dialog
box outlines the types of datum geometry you can create.
Abaqus/CAE displays prompts
in the prompt area to guide you through the procedure.
Tip:
You can also create a datum plane using the
tool, located in the module toolbox. For a diagram of the
datum tools in the toolbox, see
Using the Datum toolset.
From the list of types at the top of the dialog box, choose
Plane.
The Method list indicates the methods you can
use to create a datum plane.
From the Method list, select Rotate
from plane.
If desired, select Make Independent from the
prompt area to create the datum as an independent feature.
From the part or assembly in the current viewport, select a face or a
datum plane to rotate.
Select any edge or a datum axis to represent the axis of rotation. The
edge or datum axis you select for the axis of rotation does not have to be
coplanar with the face or datum plane you selected to rotate.
Abaqus/CAE
displays an arrow along the selected edge indicating the positive direction of
rotation using the right-hand rule.
In the text box that appears in the prompt area, type the angle of
rotation.
The datum plane appears. You can modify the angle of rotation by
selecting
FeatureEdit
from the main menu bar and selecting the datum plane. If you change the sign of
the angle,
Abaqus/CAE
reverses the direction of rotation.
