談談UG二次開發的Open和NXOpen

UG的二次開發有兩套系統，一套叫Open，一套叫NXOpen。Open主要是造型方面的功能，NXOpen比較全面。Open原來支援的是C/C++，.net的NXOpen.UF命名空間支援。NXOpen支援C++和.net等。

Open系統，支援C的原來叫UFun，或者API，用的人最多。後來出現了Open C++。但是Open C++支援編輯等屬性行為，不能建立。所以，一般是通過API建立特徵，比如實體，通過C++的類查詢和修改。

NXOpen系統，是完全物件導向的，所以可以建立和修改特徵。當然，NXOpen幾乎支援UG所有的功能。

Open

NXOpen

C

UFun（API）；面向過程開發；主要支援造型功能

C++

Open C++類庫；物件導向開發；部分支援造型功能，沒有建立特徵的功能等，需要使用UFun

通過NXOpen命名空間支援，需要包含相應標頭檔。

.net

通過NXOpen.UF命名空間封裝了UFun來實現。

通過NXOpen命名空間支援，需要引用相應的程式集。

所以，目前開來，如果使用C/C++方式，可以使用Open C和C++結合的方式，利用C來建立特徵，使用C++來管理。如果使用.net可以直接使用NXOpen。對於不熟悉NXOpen的人可以按照Open C的知識上手NXOpen.UF。

下面將通過各個例子說明上述系統的使用，因為.net平台是通用的，我只舉了C#的例子，VB等也是一樣的的。而java我不懂，見諒了。

一、Open C

1、遍曆的例子

#include <uf_object_types.h>

#include <uf_part.h>

#include <uf_obj.h>

#include <uf_modl.h>

#include <string>

#include <sstream>

using std::string;

using std::stringstream;

//下面是程式片段

UgSession session( true );

try

{

/* TODO: Add your application code here */

uf_list_p_t lpObj;

UF_MODL_create_list(&lpObj);

tag_t prt = UF_PART_ask_display_part();

tag_t Next_tag=NULL_TAG;

do

{

UF_OBJ_cycle_objs_in_part(prt,UF_solid_type,&Next_tag);

if(Next_tag==NULL_TAG) break;

int t,subtype;

UF_OBJ_ask_type_and_subtype(Next_tag,&t,&subtype);

if(subtype==UF_solid_body_subtype)

UF_MODL_put_list_item(lpObj,Next_tag);

} while(1);

logical is_open;

UF_UI_is_listing_window_open(&is_open);

if(!is_open) UF_UI_open_listing_window();

int sum;

UF_MODL_ask_list_count(lpObj,&sum);

for (int i=0;i<sum;i++)

{

tag_t t;

UF_MODL_ask_list_item(lpObj,i,&t);

stringstream s;

s<<(int)t;

string str;

str = s.str();

UF_UI_write_listing_window(str.c_str());

UF_UI_write_listing_window("\n");

}

// UF_UI_exit_listing_window();

UF_MODL_delete_list(&lpObj);

}

/* Handle errors */

catch ( const UgException &exception )

{

processException( exception );

}

2，建立block的例子

#include <uf.h>

#include <uf_ui.h>

#include <uf_exit.h>

#include <uf_modl.h>

//下面是程式片段

/* Initialize the API environment */

if( UF_CALL(UF_initialize()) )

{

/* Failed to initialize */

return;

}

/* TODO: Add your application code here */

double corner[3] ={0,0,0};

char* edge[3] = {"10","5","20"};

tag_t tag;

UF_MODL_create_block(UF_NULLSIGN,NULL_TAG,corner,edge,&tag);

/* Terminate the API environment */

UF_CALL(UF_terminate());

二、Open C++

1、遍曆的例子

#include <ug_typed.hxx>

#include <ug_part.hxx>

#include <ug_body.hxx>

#include <ug_string.hxx>

using std::string;

//下面是程式片段

UgSession session( true );

try

{

/* TODO: Add your application code here */

UgPart *pWorkPart = UgSession::getWorkPart();

UgTypedObject *pObj;

ostrstream buffer;

for ( pObj = pWorkPart->iterateFirst ( );

pObj;

pObj = pWorkPart->iterateNext ( pObj ) )

{

std::string name = pObj->getName ( );

UgBody *pBody = dynamic_cast<UgBody*>(pObj);

if (pBody)

{

buffer<<(int)pBody->getTag()<<"\n";

}

}

UgInfoWindow::open();

UgInfoWindow::write(string(buffer.str()));

delete buffer.str();

}

/* Handle errors */

catch ( const UgException &exception )

{

processException( exception );

}

2、通過模板搜尋的例子

#include <ug_body.hxx>

#include <ug_iterator.hxx>

#include <ug_string.hxx>

//下面是程式片段

UgSession session( true );

try

{

/* TODO: Add your application code here */

ostrstream buffer;

// Construct an iterator for NX face objects

UgIterator < UgBody > pObj;//workpart 可以通過其他方式指定

//UgIterator < UgFace *> curFace;

//// Loop through all faces

//while ( !curFace.isFinished ( ) )

//{

// // Get the name of the current face

// std::string faceName = (*(*curFace))->getName ( );

// curFace.findNext ( );

//}

// Loop through all faces

while ( !pObj.isFinished ( ) )

{

// Get the name of the current face

std::string faceName = (*pObj)->getName ( );

buffer<<(int)(*pObj)->getTag()<<endl;

pObj.findNext ( );

}

UgInfoWindow::open();

UgInfoWindow::write( std::string( buffer.str() ));

delete buffer.str();

}

/* Handle errors */

catch ( const UgException &exception )

{

processException( exception );

}

三、NXOpen C++

1、建立block的例子

#include <NXOpen/Session.hxx>

#include <NXOpen/Part.hxx>

#include <NXOpen/Features_BlockFeatureBuilder.hxx>

#include <NXOpen/Features_Block.hxx>

#include <NXOpen/PartCollection.hxx>

#include <NXOpen/Features_FeatureCollection.hxx>

#include <NXOpen/UI.hxx>

#include <NXOpen/NXMessageBox.hxx>

using namespace NXOpen;

//下面是程式片段

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

try

{

/* TODO: Add your application code here */

Part* thePart = theSession->Parts()->Work();

NXOpen::Features::Feature* block = NULL;

NXOpen::Features::BlockFeatureBuilder* theBuilder = thePart->Features()->CreateBlockFeatureBuilder(block);

NXOpen::Point3d basePoint(100, 100, 100);

theBuilder->SetOriginAndLengths(basePoint, "100", "200", "300");

// NXOpen.Body theBody = null;

// theBuilder.SetBooleanOperationAndTarget(NXOpen.Features.Feature.BooleanType.Create, theBody);

theBuilder->Commit();

//theBuilder->CommitFeature();

NXOpen::UI::GetUI()->NXMessageBox()->Show("", NXMessageBox::DialogType::DialogTypeInformation, "OK!");

// UI->GetUI()->NXMessageBox.Show("", NXMessageBox.DialogType.Information, "OK!");

}

/* Handle errors */

catch ( const UgException &exception )

{

processException( exception );

}

2、遍曆特徵的例子

#include <NXOpen/Session.hxx>

#include <NXOpen/Part.hxx>

#include <NXOpen/Features_BlockFeatureBuilder.hxx>

#include <NXOpen/Features_Block.hxx>

#include <NXOpen/PartCollection.hxx>

#include <NXOpen/Features_FeatureCollection.hxx>

#include <NXOpen/UI.hxx>

#include <NXOpen/NXMessageBox.hxx>

#include <NXOpen/ListingWindow.hxx>

using namespace NXOpen;

//下面是程式片段

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

try

{

/* TODO: Add your application code here */

Part* thePart = theSession->Parts()->Work();

theSession->ListingWindow()->Open();

NXOpen::Features::FeatureCollection::iterator i;

for (i=thePart->Features()->begin();i!=thePart->Features()->end();i++)

{

theSession->ListingWindow()->WriteLine((*i)->Name()+"--"+(*i)->GetJournalIdentifier());

}

NXOpen::UI::GetUI()->NXMessageBox()->Show("", NXMessageBox::DialogType::DialogTypeInformation, "OK!");

// UI->GetUI()->NXMessageBox.Show("", NXMessageBox.DialogType.Information, "OK!");

}

/* Handle errors */

catch ( const UgException &exception )

{

processException( exception );

}

四、NXOpen C#

1、建立blcok的例子

using NXOpen;

using NXOpen.Utilities;

using NXOpen.UF;

using NXOpenUI;

//下面是程式片段

Session theSession = Session.GetSession();

try

{

Part thePart = theSession.Parts.Work;

NXOpen.Features.Feature block = null;

NXOpen.Features.BlockFeatureBuilder theBuilder = thePart.Features.CreateBlockFeatureBuilder(block);

NXOpen.Point3d basePoint = new Point3d(100f, 100f, 100f);

theBuilder.SetOriginAndLengths(basePoint, "100", "200", "300");

theBuilder.Commit();

//theBuilder.CommitFeature();

UI.GetUI().NXMessageBox.Show("", NXMessageBox.DialogType.Information, "OK!");

}

catch(NXException ex)

{

UI.GetUI().NXMessageBox.Show("error!", NXMessageBox.DialogType.Error, ex.Message);

}

2、遍曆特徵的例子

using NXOpen;

using NXOpen.Utilities;

using NXOpen.UF;

using NXOpenUI;

//下面是程式片段

Session theSession = Session.GetSession();

theSession.ListingWindow.Open();

try

{

Part thePart = theSession.Parts.Work;

foreach (NXOpen.Features.Feature c in thePart.Features)

{

//NXOpen.Features.Block t = c as NXOpen.Features.Block;

//if(t!=null)

//{

// theSession.ListingWindow.WriteLine(t.ToString());

//}

theSession.ListingWindow.WriteLine(c.Name+"--"+c.ToString());

}

UI.GetUI().NXMessageBox.Show("", NXMessageBox.DialogType.Information, "OK!");

}

catch (NXException ex)

{

UI.GetUI().NXMessageBox.Show("error!", NXMessageBox.DialogType.Error, ex.Message);

}

五、NXOpen.UF

1、仿照Open C中的例1子實現

using NXOpen;

using NXOpen.Utilities;

using NXOpen.UF;

using NXOpenUI;

NXOpen.UF.UFSession theUFSession = NXOpen.UF.UFSession.GetUFSession();

try

{

double[] corner ={ 0, 0, 0 };

string[] edge = { "10", "5", "20" };

Tag tag;

theUFSession.Modl.CreateBlock1(FeatureSigns.Nullsign, corner, edge, out tag);

}

catch (NXException ex)

{

UI.GetUI().NXMessageBox.Show("error!", NXMessageBox.DialogType.Error, ex.Message);

}

2、仿照Open C中的例子2實現

using NXOpen;

using NXOpen.Utilities;

using NXOpen.UF;

using NXOpenUI;

NXOpen.UF.UFSession theUFSession = NXOpen.UF.UFSession.GetUFSession();

try

{

Tag[] list=null;

Tag thePart = theUFSession.Part.AskDisplayPart();

theUFSession.Modl.CreateList(out list);

Tag Next_tag=Tag.Null;

do

{

theUFSession.Obj.CycleObjsInPart(thePart,70/* UF_solid_type*/,ref Next_tag);

if (Next_tag == Tag.Null) break;

int t, subType;

theUFSession.Obj.AskTypeAndSubtype(Next_tag,out t, out subType);

if (subType == 0/*UF_solid_body_subtype*/)

theUFSession.Modl.PutListItem(list, Next_tag);

} while (true);

bool isOpen;

theUFSession.Ui.IsListingWindowOpen(out isOpen);

if (!isOpen) theUFSession.Ui.OpenListingWindow();

int sum;

theUFSession.Modl.AskListCount(list,out sum);

for (int i = 0; i < sum;i++ )

{

Tag t;

theUFSession.Modl.AskListItem(list, i, out t);

theUFSession.Ui.WriteListingWindow(t.ToString());

}

/*Treat all the arguments with the"Output to be freed " annotation as an output parameter.

* The system takes care of freeing memory.*/

}

catch (NXException ex)

{

UI.GetUI().NXMessageBox.Show("error!", NXMessageBox.DialogType.Error, ex.Message);

}
