Fixtures

Creates an array of fixtures that are extracted from other In-Sight Vision Tools that return positional data which can be used as inputs to the ViDi and ViDiRead functions, allowing the Cognex ViDi Tools to use an external fixture provided by In-Sight Vision Tools.

Note: Since the Fixtures function can accept a variable list of cell values, this function is not configured through a property sheet. This function can be configured directly in the cell, or in the Formula Bar on the Job Edit toolbar, either by typing in cell values directly, or selecting the cell references of the supported data structures.
Syntax: Fixtures(Cell0, Cell1, Cell2, ...)
