NX二次开发-获取图纸尺寸上椭圆边界框的大小

void AskDimBoundary(tag_t dim_tag)

{

       //获得尺寸字体大小

       int dim_subtype = 0;

       double dim_origin[3];

       UF_DRF_dim_info_p_t dim_info;

       UF_DRF_ask_dim_info(dim_tag, &dim_subtype, dim_origin, &dim_info);

       double DimSize = dim_info->text_info->size;

       NXOpen::Session *theSession = NXOpen::Session::GetSession();

       NXOpen::Part *workPart(theSession->Parts()->Work());

       NXOpen::Part *displayPart(theSession->Parts()->Display());

       //获得尺寸的高度因子

       NXOpen::Annotations::HorizontalDimension *horizontalDimension1(dynamic_cast<NXOpen::Annotations::HorizontalDimension *>(NXOpen::NXObjectManager::Get(dim_tag)));

       NXOpen::Annotations::LinearDimensionBuilder *linearDimensionBuilder1;

       linearDimensionBuilder1 = workPart->Dimensions()->CreateLinearDimensionBuilder(horizontalDimension1);

       double height_size = linearDimensionBuilder1->Style()->LetteringStyle()->GdtFrameHeightFactor();

       //计算椭圆框的高度(字体大小*高度因子)

       double block_height = DimSize * height_size;

       //计算椭圆框的宽度(字体大小*高度因子*2)

       double block_length = DimSize * height_size * 2;

       

       //打印

       char msg[256];

       sprintf_s(msg, "高度%f 宽度%f", block_height, block_length);

       UF_UI_open_listing_window();

       UF_UI_write_listing_window(msg);

}

 

宽度乘以2我记得好像是之前请教的唐工
