AddTangent Method

Description

Adds a tangent relationship to a Relations2d collection.

Syntax

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

Parameters

Object1: Specifies the first object to which the tangent relationship is to be applied.
Object2: Specifies the second object to which the tangent relationship 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 Tangent relationship between the first object and 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.
