C# .net 通过NamedBoundaries如何创建SavedView

试试NamedView下的SetClipElement，这个函数的参数是NamedBoundaries那个ShapeElement

NamedView namedview = new NamedView(dgnFile, namedBoundary1.Name);
namedview.SetClipElement(namedBoundary1.GraphicalElement);
namedview.WriteToFile();

这样保存的SavedView，参考过去显示没有Element。

用mdlView_setClipBoundaryElement试了也没有Element。

你弄个新的文件，在原点附近画几个简单的图形去测试，弄这么复杂的模型去测试，非常不利于观察结果。

测试后，该方法仅对种子文件为2D的文件可以，对种子文件为3D的生成savedview，参考过来就什么都没有。

你按照程序里边的数据，手动操作一下看是否有效果。

手动操作用的named boundaries 里边右键creatdrawing，弹出对话框，选择后创建出来的是有东西的。

我用C++写了如下测试代码是可以的。你先仿照此C++代码用C#实现一下看。

void createSavedViewFromNamedBoundary(WCharCP)
{
	NamedBoundaryPtr namedBdry = NamedBoundary::FindByName(WString(L"FooNamedBdary"), NULL, *ACTIVEMODEL);
	if (!namedBdry.IsValid())
	{
		mdlDialog_dmsgsPrint(L"NamedBoundary::FindByName FAILED");
		return;
	}

	DgnFileP dgnFile = ISessionMgr::GetActiveDgnFile();
	NamedViewPtr namedView = nullptr;
	if (NamedViewStatus::Success != NamedView::Create(namedView, *dgnFile, L"MyNamedView"))
	{
		mdlDialog_dmsgsPrint(L"NamedView::Create FAILED");
		return;
	}
	ViewGroupCollectionCR   viewGrpCol = dgnFile->GetViewGroups();
	ViewGroupCP             activeViewGrp = viewGrpCol.GetActiveCP();
	ViewInfoCR              viewInfo = activeViewGrp->GetViewInfo(tcb->lstvw);
	ViewPortInfoCR          viewPortInfo = activeViewGrp->GetViewPortInfo(tcb->lstvw);

	namedView->SetClipElement(namedBdry->PeekGraphicalElement());
	namedView->SetViewInfo(viewInfo);
	namedView->SetViewPortInfo(viewPortInfo);
	namedView->SynchViewBoundaryWithClipVolume(ViewBoundarySynchOptions());
	namedView->WriteToFile();
}
