#### Extension Methods

[LinkPropertyItemCache.GetLinkProperties(object, LinkPropertyType)](VM.Models.Pre.Cache.LinkPropertyItemCache.md#VM_Models_Pre_Cache_LinkPropertyItemCache_GetLinkProperties_System_Object_VM_Models_Pre_LinkPropertyType_), [LinkPropertyItemCache.GetLinkPropertiesAndValues(object, LinkPropertyType)](VM.Models.Pre.Cache.LinkPropertyItemCache.md#VM_Models_Pre_Cache_LinkPropertyItemCache_GetLinkPropertiesAndValues_System_Object_VM_Models_Pre_LinkPropertyType_), [LinkPropertyItemCache.GetLinkedObjects&lt;T&gt;(object, LinkPropertyType)](VM.Models.Pre.Cache.LinkPropertyItemCache.md#VM_Models_Pre_Cache_LinkPropertyItemCache_GetLinkedObjects__1_System_Object_VM_Models_Pre_LinkPropertyType_)

## Methods

### <a id="VM_API_Pre_GeometryAPI_ExportCAD_VM_Models_Pre_IDocument_System_String_System_Collections_Generic_IEnumerable_VM_API_Pre_Obj__System_String_"></a> ExportCAD(IDocument, string, IEnumerable&lt;Obj&gt;, string)

Export the geometry.

```csharp
[NotNull(new string[] { "document", "objectList" })]
[NotNullOrEmpty(new string[] { "filePath" })]
public static void ExportCAD(this IDocument document, string filePath, IEnumerable<Obj> objectList, string value)

```

#### Parameters

`document` IDocument
