To define local axis systems.
Refer to User-Defined Axes for further information on this feature.
The keyword starts with a line defining the name of the axis system. This is then followed by a line with 6 numbers.
Line defining the axis system name:
NAME=AXIS NAME
Line defining an axis system:
X1, Y1, Z1, X2, Y2, Z2
The two vectors defining an axis system must have non-zero length and must be orthogonal.

Description |
Name: |
A unique label for the axis system being defined. |
X1: |
The component in the global X-direction of the local x-axis of the axis system being defined. See Note (a). |
Y1: |
The component in the global Y-direction of the local x-axis of the axis system being defined. See Note (a). |
Z1: |
The component in the global Z-direction of the local x-axis of the axis system being defined. See Note (a). |
X2: |
The component in the global X-direction of the local y-axis of the axis system being defined. See Notes (a) and (b). |
Y2: |
The component in the global Y-direction of the local y-axis of the axis system being defined. See Notes (a) and (b). |
Z2: |
The component in the global Z-direction of the local y-axis of the axis system being defined. See Notes (a) and (b). |
(a)If you do not specifically input a value in any of Columns 2-7, then the corresponding variable defaults to zero. Note however that all three of X1, Y1 and Z1 or all three of X2, Y2 and Z2 cannot equal zero – the null vector cannot be either the local x-axis or the local y-axis.
(b)Note that the local x-axis and local y-axis that you define here must be orthogonal, that is, the true angle between the two vectors defining the local x- and y-axes must be 90°. Flexcom will generate an error message if this is not the case, as vectors that are not orthogonal cannot be used to form a valid axis system.
