该命令有如下参数：
OutputMeshType - 输出网格类型，若OutputMeshType=Separated，则输出网为顶部、底部及侧边，若OutputMeshType=Jointed，则输出一个融合网格。
The command has the following inputs:
OutputMeshType - the type of the output meshes, if OutputMeshType = Separated, the output meshes are separated into the top, the bottom and the side-wall, else if OutputMeshType = Jointed, the output mesh is a joined mesh.

这里是一个您可尝试的例子：DProject.3dm。
Here is the example for you to try: DProject.3dm.

选择需投影的网格及曲面并使用该命令。
Select the surface and the mesh to project and use this command.

在运行该命令后，网格将被投影至曲面上。
After running this command, the mesh will be projected to the surface.

下图显示OutputMeshType = Jointed的结果。
The following figure shows the result when OutputMeshType = Jointed.

下图显示OutputMeshType = Separated的结果。
The following figure shows the result when OutputMeshType = Separated.
