Exchange Axes

(This functionality is available with the Computations module)

Swaps the X, Y, Z axes with each other. This function is particularly useful for façade surveys where it is desirable to view a building from the front rather than from above.

The Edit / Exchange Axes command is selected from the Computations Task.

Exchange Axes dialog box

Item	Used to
X Axis =	Select which current axis is to represent the new positive X axis. The orientation can also be changed by selecting a current negative axis.
Y Axis =	Select which current axis is to represent the new positive Y axis. The orientation can also be changed by selecting a current negative axis.
Z Axis =	Select which current axis is to represent the new positive Z axis. The orientation can also be changed by selecting a current negative axis.
OK	Checks that the selected axes are all valid. All axes must be selected - i.e. X, Y and Z selections must result in unique X, Y and Z selections (negatives are also selectable). Makes a backup of the current .SEE data file with a .BAK extension in the current working folder, as the results may be irreversible. Transforms the data set.
Cancel	Closes the dialog box without exchanging the axes.

Notes:
This command is not available in a projection as the co-ordinates would be transformed out of the projection range.

All LISCAD objects are converted and re-validated after the axes are exchanged. As a result some elements may be deleted - e.g. a spiral when x is exchanged to z.

Z co-ordinates may no longer be legal when exchanged for X or Y's as values less than -9999.999 are not permissible.
