The following methods are available:
-
Principal axis
-
Select one of the three principal axes with which the datum axis must be
colinear, as shown in
Figure 1.
For detailed instructions, see
Creating a datum axis along a principal axis.
-
Intersection of 2 planes
-
Select two non-parallel planar surfaces.
Abaqus/CAE
creates the datum axis where the two planes (or extensions of the two planes)
intersect, as shown in
Figure 2.
For detailed instructions, see
Creating a datum axis along the intersection of two planes.
-
Straight edge
-
Select a straight edge on the model with which the datum axis must be
colinear, as shown in
Figure 3.
For detailed instructions, see
Creating a datum axis along a straight edge.
-
2 points
-
Select any two points on the model through which the datum axis must pass,
as shown in
Figure 4.
For detailed instructions, see
Creating a datum axis through two points.
-
Axis of cylinder
-
Select a cylindrical face on the model.
Abaqus/CAE
creates a datum axis that lies along the axis of the cylindrical face, as shown
in
Figure 5.
For detailed instructions, see
Creating a datum axis along the axis of a cylinder.
-
Normal to plane, thru point
-
Select a plane and a point that is not on the plane.
Abaqus/CAE
creates a datum axis that is normal to the plane and passes through the point,
as shown in
Figure 6.
For detailed instructions, see
Creating a datum axis normal to a plane and passing through a point.
-
Parallel to line, thru point
-
Select an edge of the model and a point outside the edge.
Abaqus/CAE
creates a datum axis that is parallel to the edge and passes through the point,
as shown in
Figure 7.
For detailed instructions, see
Creating a datum axis parallel to a line and passing through a point.
-
3 points on circle
-
Select three points on the model that define a circle.
Abaqus/CAE
creates a datum axis along the axis of the circle, as shown in
Figure 8.
For detailed instructions, see
Creating a datum axis running along the axis of a circle defined by three points.
-
Rotate from line
-
Select an edge and an axis of rotation, and specify the angle through which
the edge will be rotated.
Abaqus/CAE
creates a datum axis by rotating the edge about the axis through the specified
angle, as shown in
Figure 9.
For detailed instructions, see
Creating a datum axis by rotating an existing edge through a specified angle.
