1、设置显示模式

1.1 增加按钮添加消息响应函数

//线框
void COCCDemoDoc::OnButtonWireframemode()
{
	//关闭边界框
	const Handle(Prs3d_Drawer)& aDrawer = m_AISContext->DefaultDrawer();
	aDrawer->SetFaceBoundaryDraw(false);
	//线框
	m_AISContext->SetDisplayMode(AIS_WireFrame, false);
	m_AISContext->Redisplay(AIS_KOI_Shape, -1, true);

}

//实体
void COCCDemoDoc::OnButtonEntitemode()
{
	//关闭边界框
	const Handle(Prs3d_Drawer)& aDrawer = m_AISContext->DefaultDrawer();
	aDrawer->SetFaceBoundaryDraw(false);
	//实体
	m_AISContext->SetDisplayMode(AIS_Shaded, false);
	m_AISContext->Redisplay(AIS_KOI_Shape, -1, true);
}

//实体线框
void COCCDemoDoc::OnButtonEntitywire()
{
	//开启边界框
	const Handle(Prs3d_Drawer)& aDrawer = m_AISContext->DefaultDrawer();
	aDrawer->SetFaceBoundaryDraw(true);
	//实体
	m_AISContext->SetDisplayMode(AIS_Shaded, false);
	m_AISContext->Redisplay(AIS_KOI_Shape,-1, true);
	
}

2、效果如图
