EffectInstance.IsValid

Public Class

Tests whether the effect instance is valid for rendering.

Namespace: Autodesk.Revit.DB.DirectContext3D

Assembly: RevitAPI (in RevitAPI.dll) Version: 25.0.0.0 (25.0.0.0)

Syntax

public bool IsValid()

Return Value

Boolean
True if the effect instance is valid for rendering, false otherwise.

Remarks

The effect instances are internally associated with low-level graphics state and may become invalidated when the state changes. Therefore, an application should test each effect instance for validity before using it when submitting geometry. If the effect instance becomes invalid, the application should re-create it.
