Subject: [Acis-alliance] How to get a bounding box in acisR11

hello zhang

Nomally acis does not set a bounding box of bodies.

if you want to get the box of the bodies.
So you should calculate a bounding box as follows....

ENTITY_LIST face_list
api_get_faces( pBody, face_list );
SPAbox box ;
for( int iface = 0 ; iface < face_list.count ; ++iface) {
  SPAbox box_tmp = get_face_box( face_list[iface] ) ;
  box += box_tmp ;
}

sometimes you need set an option with 
api_set_int_option( "tight_tours_box",TRUE ) ;

hi, everyone,

I am trying to use is_FACE function to check if an entity is a FACE. but an error occurred when I compiled it. I have included the file as the Doc suggested. 
can anyone give me a hint?

E:\research\program\test\test.cpp(302) : error C2061: syntax error : identifier 'is_FACE'.

Fraid so.  Mind this was a very long time back (acis4 or 3 I think) and the
application I tried it in was very messy (written by committee), but I had a
lot of problems with this approach.  I would like to hear from someone who
has used it successfully and measured the memory results as well as the time
involvement.  From the documentation it looks like the notestate/delete
delta state methodology will still be needed to erase empty bb's and if I
remember right I did not do that at the time.

I turn the whole bulletin board stuff of with api_logging( FALSE). At least
I was thinking that this is the action the function does. This seems the
simplest way to me to get rid of the memory overhead. Did you make some
other experiences?

Subject: [Acis-alliance] progress of api_restore_entity_list()?
Message-ID: <[e-mail]>

Hello,

is there any possibility to inquire the progress
of  api_restore_entity_list()? A function
like api_xiges_set_interopstatus_callback() to
set a callback function during reading a sat-file
would be nice. Unfortunately, I haven't found
anything in the online-docu.

background: we would like to show a progress bar
during loading a sat-file.


Thanks for any help,
    Juergen

There are some lines here saying ARCH=NT_DLL but I
have ARCH set to NT_DLLD. I'm not sure if this has
anything to do with it. I have gone through the
archives both here and on the Hoops discussion forum
and there generally seems to be trouble getting these
applications to work.

I am using ACIS R11 and Hoops 9. Does anyone have any
ideas?
Thanks in advance.

Subject: [Acis-alliance] sg_potential_partners( )?
Message-ID: <[e-mail]>

Hi dear ACIS fellows,

Does anybody know the purpose of the third parameter in

"sg_potential_partners((EDGE*)elist2[j], (EDGE*)tmp1[i], vlist2) )"?

Here this is vlist2.

As far as I understand, this function checks whether two edges could be
partners in a following stiching process. In the according header file
nothing is said about the third parameter. The only information is, that it
is a entity_list.

Any hints welcome!

Greetings
Markus

Subject: [Acis-alliance] How to delete a loop
Message-ID: <[e-mail]>

Dear acis-alliance fellows,

  I want to delete the holes in faces, and do not want to realize it by reconstruct a face in the hole. So I think it is maybe possible to do it by deleting the inner loop of a FACE. I do not know how to realize it in program. 
  Does anyone know how to do? The following codes is my program, Who can tell me what wrong in it?

ENTITY_LIST face_list;//existed
	for(i=0;i<count;i++)
	{
		if(is_BODY(face_list[i]))
		{
		    BODY *body=(BODY*)face_list[i];
			LUMP * ll=body->lump();
			while (ll!=NULL) {
				SHELL * she=ll->shell();
				while (she!=NULL) {
					FACE *ff=she->face_list();
					while (ff!=NULL) {
						LOOP * loop_ff=ff->loop();
	  					while (loop_ff!=NULL) {
							num_loop++;
							api_loop_external(loop_ff,if_external,NULL);
							if(!if_external) num_inter_loop++;
							api_loop_type(loop_ff,looptype,NULL);
							COEDGE * cc=loop_ff->start();
							if((looptype==loop_hole)&&(cc->partner()==NULL)) 
							{
								num_hole++;
                                LOOP * temloop=loop_ff->next();
                                loop_ff->lose();
                                loop_ff=temloop;
                                goto l1;
								
							}
							loop_ff=loop_ff->next();
l1:                         delete_num=0;
	  					}
						ff=ff->next();
					}
					she=she->next();
				}
				ll=ll->next();
			}
		}
	}

Thank you !

Subject: [Acis-alliance] How to use InterOp Catia v5 Reader
Message-ID: <[e-mail]>

Dear all,

  I want to open Catia V5 file by using InterOp Catia v5 Reader and have installed it. Now I build a ACIS Hoops MFC Application with Catia reaing fuction. I have passed compiling and linking. When I using it to open Catia file, the program will use lots of time and resource. The  result is still nothing. I try to realize it in console application, the error information is : Message catalog not found or includes syntax error in CATCommand. The following code is my function of open CATIA file in MFC program:
void CMyAHAppR12Doc::OnImportCatiaV5() 
{
// *** NOTE ***
// InterOp CATIA V5 works only on Release DLLs.

#ifndef _DEBUG
	CFileDialog my_dlg(TRUE, "CATPart", NULL, OFN_HIDEREADONLY |
		OFN_OVERWRITEPROMPT, "CATIA V5 Part Files (*.CATPart)|*.CATPart|CATIA V5 Product Files (*.CATProduct)|*.CATProduct|" , NULL);
	if (my_dlg.DoModal() == IDOK)
	{
		if (my_dlg.GetFileExt().CompareNoCase("CATPart") == 0 || my_dlg.GetFileExt().CompareNoCase("CATProduct") == 0)
		{
			int depth = 0;
			api_part_start_state(depth);

			ENTITY_LIST	elist;
			api_initialize_aciscatiav5rd();

			API_BEGIN

				api_catiav5_read_free_edges(TRUE);
				
				result = api_catiav5_convert_catiav5_to_acis_entlist(my_dlg.GetPathName(), elist, NULL, NULL);
				if (result.ok())
				{
					ENTITY*		pEnt = NULL;
					elist.init();
					while( (pEnt = elist.next()) != NULL )
					{
						m_pAHDoc->AddEntity(pEnt);
					}

					m_pAHDoc->ZoomAll();
					m_pAHDoc->RefreshViews();			
				}
				else
				{
					const char* emess = find_err_mess(result.error_number());
					AfxMessageBox(emess, MB_OK);
				}

			API_END

			api_terminate_aciscatiav5rd();

			elist.clear();

			api_part_note_state(outcome(API_SUCCESS), depth );
		}
	}

#endif

}

  My ACIS and InterOp is R12 Sp6, program is run in realease. Does anyone can tell me what is wrong with my program?
