Creating a datum axis along the intersection of two
planes
You can position a datum axis by selecting two nonparallel planar
surfaces.
Abaqus/CAE
creates the datum axis where the two planes, or a projection of the two planes,
intersect.
The figure below shows an example of creating a datum axis at the
intersection of two planes.
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
Intersection of 2 planes.
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 plane.
Select a second plane that is not parallel with the first.
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.
