## Methods

### ExportCAD(IDocument, string, IEnumerable<Obj>, 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

The document to export the geometry.

`filePath` [string](https://learn.microsoft.com/dotnet/api/system.string)

The file path of the geometry.

`objectList` [IEnumerable](https://learn.microsoft.com/dotnet/api/system.collections.generic.ienumerable-1)&lt;[Obj](VM.API.Pre.Obj.md)&gt;

The result type of the geometry.

`value` [string](https://learn.microsoft.com/dotnet/api/system.string)

The unit type of the geometry.

#### Exceptions

[ArgumentNullException](https://learn.microsoft.com/dotnet/api/system.argumentnullexception)

Will be thrown if 'document', 'filePath' argument is null.

[ArgumentException](https://learn.microsoft.com/dotnet/api/system.argumentexception)

### ImportCAD(IDocument, string, ResultType, CadImportUnitType, bool, CadImportColorType, Color?)

Import the geometry.

```csharp
[NotNull(new string[] { "document" })]
[ExistFile(new string[] { "filePath" })]
public static void ImportCAD(this IDocument document, string filePath, ResultType resultType = ResultType.Default, Document3D.CadImportUnitType unitType = CadImportUnitType.Auto, bool useHealing = true, Document3D.CadImportColorType colorType = CadImportColorType.Default, Color? color = null)

```

#### Parameters

### ReplaceCAD(IDocument, string, ResultType, CadImportUnitType, bool, CadImportColorType, Color?, bool, string\[\])

Replace the geometry.

```csharp
[NotNull(new string[] { "document" })]
[ExistFile(new string[] { "filePath" })]
public static void ReplaceCAD(this IDocument document, string filePath, ResultType resultType = ResultType.Default, Document3D.CadImportUnitType unitType = CadImportUnitType.Auto, bool useHealing = true, Document3D.CadImportColorType colorType = CadImportColorType.Default, Color? color = null, bool replaceAllGeometries = true, string[] attributes = null)
