问题

我对OPEN CASCADE非常不熟悉。
有人可以告诉我如何从用于查看形状的AIS_InteractiveObject中获取形状吗？
谢谢。

没有直接的函数来获取形状。我查阅了Open CASCADE文档中的类描述。

英文:

I'm very new to OPEN CASCADE.
Can someone please let me know how to get the shape from AIS_InteractiveObject which used to view the shapes.
Thanks.

There are no direct functions to get the shapes. I checked with the class discription in Open CASCADE documentation.

"Let's say you have your AIS_InteractiveObject called 'interactiveObj'.
You can downcast this to 'AIS_Shape' first.

interactiveObj = ... ; // your interactive object
Handle(AIS_Shape) aisShape = Handle(AIS_Shape)::DownCast(interactiveObj ); // 转换为 AIS_Shape

Then you can get the TopoDS_Shape from the object.

TopoDS_Shape shape = aisShape->Shape();

This is the simple method.

TopoDS_Shape shape = Handle(AIS_Shape)::DownCast(interactiveObj)->Shape(); // 获取 TopoDS_Shape"

You can downcast this to "AIS_Shape" first.

interactiveObj = ... ; // your interactive object
Handle(AIS_Shape) aisShape = Handle(AIS_Shape)::DownCast(interactiveObj ); // convert to AIS_Shape

Then you can get the TopoDS_Shape from the object.

TopoDS_Shape shape = aisShape-&gt;Shape();

This is the simple method.

TopoDS_Shape shape = Handle(AIS_Shape)::DownCast(interactiveObj)-&gt;Shape(); // get the TopoDS_Shape
