您好，在本文中，我将列出Aspose.CAD与其他类似软件的不同之处，并通常介绍其有趣的功能。
导出到指定的输出尺寸
例如，可以设置输出PDF文件的特定尺寸来导出到A4尺寸的文档。有一个有关如何设置Aspose.CAD以输出所需PDF大小的示例。导出区域的内容将被缩放以适合输出文档区域，而不改变长宽比。还要注意，该代码示例还包含栅格输出的示例，该示例更为简单，只需将所需的DPI乘以所需的输出文档尺寸，就可以得到所需的栅格图像分辨率。

出口的绝对指标正常化
默认情况下，Aspose.CAD使用工程图的相对单位。但是，CadRasterizationOptions类中有一个UnitType属性，该属性指定使用的单位类型。在渲染期间，一个单位将被解释为1个像素，因此，如果图像的指定大小为10x10 m，并且选择厘米为单位类型，则该图像将被光栅化为1000x1000像素的图像。

支持PDF / A
Aspose.CAD支持指定符合PDF/A标准来呈现归档PDF文档。该过程包括创建用于导出图像的常规PdfOptions，将其CorePdfOptions属性设置为PdfDocumentOptions的新实例，并在实例中设置遵从性字段。之后，使用该PdfOptions实例保存的图像将被保存为PDF/兼容的PDF文件。例子:

出口期间的保证金控制。
默认情况下，Aspose.CAD渲染CAD文件时，文件或页面的整个内容周围的边距很小。CadRasterizationOptions 类中有一个Zoom 属性，用于控制图像缩放。默认情况下，它设置为小于1，以提供边距。如果不需要边距，请将其设置为1。示例：

跟踪出口错误
Aspose.CAD有一种方法可以记录将CAD文件导出到栅格或PDF期间发生的错误。CadRasterizationOptions 类中有一个RenderResult 事件，当导出完成时会调用该事件。事件处理程序会收到CadRenderResult ，其中在“ 失败” 字段中包含错误列表。查看有关如何使用它的示例：

3D对象导出支持
可以使用Aspose.CAD导出AutoCAD和其他文件格式的3D对象。该库使用存储在文件中的视点-因此，导出的图像将显示为与加载文件后立即在AutoCAD中可以看到的图像相同。
默认情况下，仅2D对象导出为AutoCAD文件。若要切换到3D对象导出，请将CadRasterizationOptions实例的TypeOfEntities属性设置为TypeOfEntities .Entities3D并执行导出。 请注意，IFC文件没有存储视点信息，因此您必须在导出期间提供观察点。参见示例：

多线程支持
通过Aspose.CAD加载的所有CAD文件-的图片类的实例-是独立的，并且可以毫无问题并行处理。但是，对单个图像的操作应仅在一个线程内发生。
即将推出-.Net Core支持
.NET标准将在不久的将来得到支持，因此该库将具有一个本机.NET Core支持的版本，因此，不仅Java中而且在.Net中都支持多平台。
即将推出-云版本
一项公共的REST API服务正在允许您使用Aspose.CAD，将文件上传到API主机，对其进行处理并将其下载回来。
现在，仅此而已！将来，本文将使用新的和旧的有趣功能进行更新。
