AddPointOn Method

Description

Adds a point-on relationship to a Relations2d collection.

Syntax

Visual Basic
Public Function AddPointOn( _ ByVal Object1 As Object, _ ByVal Index As Long, _ ByVal Object2 As Object, _ Optional ByVal guaranteed_ok As Variant _ ) As Relation2d

Parameters

Object1: Specifies the first object to which the constraint is to be applied.
Index: Specifies the key point index of Object1.
Object2: Specifies the second object to which the constraint is to be applied.
guaranteed_ok: If set, checking is performed to ensure that the relationship does not contradict previously placed relationships.

Remarks

The method creates a point-on relationship between the key point index of the first object to a point on the second object. Relationship Add methods have checks to ensure that a new relationship does not contradict previously placed relationships. For example, AddHorizontal will return an error if the line already has a vertical relationship. This check can be turned off to enhance performance. The optional “guaranteed_ok” argument, if set to 1, bypasses relationship checking. However, this feature could leave the system in an unsolvable state, so use it with extreme caution. It is best to use this feature only on a new element with no other relationships.
