Description
Constraints are used in an Assembly document to define the relationship between component occurrences. A constraint should never be over constrained but at times based on requirements, it might be under constrained. This Design supports Mate, Flush, Insert and Angle constraint.

Data passed in here is stored as Inventor’s attributes on this object. Only string values can be stored and the structure is "[["AttSetName" ,["AttName","AttValue""]], ["AttSetName1" ,["AttName1","AttValue""]]…]" Where AttSetName = AttributeSet name AttName = Attribute name AttValue = Attribute value
Example: "[["myData" ,["County","Orange""]],["ExportPaths" , ["PartSheet", "C:\\temp\\cache\\Parts"]], [ "ExportPaths" , ["AssemblySheet", "C:\\temp\\cache\\Assemblies"]]" |

Project Example
In your kBridge Examples Projects folder open the project called ‘Table_KB_Inventor_Example’.
Link:
https://knowledgebridge.engineer/projects
Reference Location:
"world.tableapplication1.tables.tables0.constraintangle.constraintangle0"
Example: The ConstraintAngle sets the angle of the book placed on the table.
Reference location:
"world.tableapplication1.tables.tables0.constraintflush.constraintflush0"
Example: The ConstraintFlush sets the elevation of the book.
Reference location:
"world.tableapplication1.tables.tables0.books.books0"
Example: To see the book on top of the table in kBridge Graphics, you need to add a formula to the books Parameter rule ‘Position’. Because you added constraints, in Inventor the constraints will overrule the ‘Position’ rule.
If you leave the Position rule empty the default will be { origin: p(0, 0, 0, this.parent.transform ) }. The book will be centered inside the table top and will not be visible unless you set the view to wireframe. Again, the book will show up in the correct location in Inventor because of the constraints.
