Rule (Object)

Represents the program relation.
The following example shows how to create a program that selects a depth with respect to a mass value. The depth and mass parameters should exist before the creation of the program (also called Rule) object.

	Dim CATDocs As Documents
 Set CATDocs = CATIA.Documents
 Dim part1 As Document
 Set part1   = CATDocs.Add("CATPart")
 Dim mass As RealParam
 Set mass         = part1.Part.Parameters.CreateReal("mass", 5.)
 Dim depth As RealParam
 Set depth        = part1.Part.Parameters.CreateReal("depth", 0.)
 Dim selectdepth As Relation
 Set selectdepth = part1.Part.Relations.CreateProgram
                    ("select_depth",
                     "Select depth with respect to mass", 
                     "if (mass>2kg) { depth=2mm } else { depth=1mm }")
