nx二次开发 获取边界类型

NX二次开发中获取边界类型可以使用以下代码:
```
#include <NXOpen/Part.hxx>
#include <NXOpen/Body.hxx>
#include <NXOpen/BodyCollection.hxx>
#include <NXOpen/Edge.hxx>
#include <NXOpen/EdgeCollection.hxx>
#include <NXOpen/Features_Feature.hxx>
#include <NXOpen/Features_FeatureCollection.hxx>
#include <NXOpen/Features_FeatureType.hxx>
#include <NXOpen/TopologicalRegion.hxx>
#include <NXOpen/TopologicalRegionCollection.hxx>
#include <NXOpen/TopologyQuery.hxx>
using namespace NXOpen;
void GetBoundaryType()
{
Part *part = NXOpen::Session::GetSession()->Parts()->Work();
BodyCollection *bodies = part->Bodies();
Features::FeatureCollection *features = part->Features();
// Loop through all the bodies in the part
for (int i = 0; i < bodies->Count(); i++)
{
Body *body = bodies->GetItem(i);
// Loop through all the edges in the body
EdgeCollection *edges = body->GetEdges();
for (int j = 0; j < edges->Count(); j++)
{
Edge *edge = edges->GetItem(j);
// Check if the edge is a boundary edge
TopologicalRegionCollection *regions = edge->GetTopology()->GetRegions();
if (regions->Count() == 1)
{
TopologicalRegion *region = regions->GetItem(0);
if (region->IsSolidRegion())
{
// The edge is a boundary edge of a solid body
// Do something
}
else if (region->IsSheetRegion())
{
// The edge is a boundary edge of a sheet body
// Do something
}
else if (region->IsWireframeRegion())
{
// The edge is a boundary edge of a wireframe body
// Do something
}
}
}
// Loop through all the features in the body
for (int j = 0; j < features->Count(); j++)
{
Features::Feature *feature = features->GetItem(j);
// Check if the feature is a boundary feature
if (feature->Type() == Features::FeatureType::Boundary)
{
// The feature is a boundary feature
// Do something
}
}
}
}
```
这段代码会遍历当前工作部件中所有的边界,然后通过`GetTopology()`方法获取边界的拓扑结构信息,再通过`GetRegions()`方法获取边界的区域信息,最后根据区域的类型确定边界的类型。另外,还可以通过遍历部件中的所有特征,判断特征类型是否为边界,来获取所有的边界类型。
