The figure below shows an example of creating a datum axis by selecting a
principal axis.
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 axis 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
Axis.
The Method list indicates the methods you can
use to create a datum axis.
From the Method list, select Principal
axis.
Select the principal X-,
Y-, or Z-axis through
which your datum axis must pass.
The datum axis appears. You cannot modify a datum axis created with
this method; you must delete the old axis and create a new one.
