Workspace Node: Cartesian Variables - Specifications Tab

The Cartesian Variables workspace node can be accessed from the Feature Finder, ribbon bar, or Node Browser. Double-click the node to display the specifications dialog box.

The Cartesian method of merging files creates a cross product of the variables. Every combination of every case will be created.

For example:

File 1:

SEAT	DYNAMO
DOWN	OFF
UP	ON

File 2:

GEAR	TIRES
MEDIUM	HARD
LOW	SOFT

Result:

SEAT	DYNAMO	GEAR	TIRES
DOWN	OFF	MEDIUM	HARD
DOWN	OFF	LOW	SOFT
UP	ON	MEDIUM	HARD
UP	ON	LOW	SOFT

A possible application of a Cartesian merge is to generate an experimental design spreadsheet.
