 Last update: 16.07.2025 

Namespace: [VM.Managed.DAFUL](VM.Managed.DAFUL.md)  
Assembly: VMDFBase.dll

This interface is to represent the connetable rigid 3 dimension object.

```csharp
public interface IContactableRigid3D : IContactableRigid, IContactable3D, IContactable, IGeometricalComponent, IEntityRelation, IBodyAnalysisType, IHasBody

```

#### Implements
