Hi
you need to use ee->loop()->face() instead of ee->owner()->face()

Hi everyone of acis-alliance,

  I want to judge if a two faces are adjacent in a ENTITY_LIST. I use CODEGE to realize it.  This is my codes:
---------------------------------------------------------------------------
    for (int i = 0; i < face_list.count(); i++) 
	{
		if(is_BODY(face_list[i]))
		{
			BODY *body=(BODY*)face_list[i];
			COEDGE *ee=body->lump()->shell()->face_list()->loop()->start();
			while(ee!=NULL){
				FACE *face=ee->owner()->face();
				COEDGE *par_ee=ee->partner();
				FACE *adj_face=par_ee->owner()->face();
				num_codege++;
				ee=ee->next();
				if(adj_face!=face)
				{
					face_adj_edge.add(face);
					face_adj_edge.add(adj_face);
				}
			}
		}
	}
---------------------------------------------------------------------------
But I can not pass the compiling, the error is :
--------------------Configuration: ACISR10 - Win32 Debug--------------------
Compiling...
ACISR10Doc.cpp
F:\lzguo\program\ACISR10\ACISR10Doc.cpp(836) : error C2039: 'face' : is not a member of 'ENTITY'

Error executing cl.exe.
Creating browse info file...
ACISR10.exe - 5 error(s), 0 warning(s)

Should I use the follow method to realize, but when I use it to judge , the program will hold on. 
------------------------------------------------------------------------
void get_faces_of_edge(EDGE *edge, ENTITY_LIST &faces)
{
	faces.add( ((LOOP *)edge->coedge()->owner())->face() );
    faces.add( ((LOOP *)edge->coedge()->partner()->owner())->face() );
}
-------------------------------------------------------------------------
Who can tell me what is the error in my two codes, and how to do? Thank you very much.

Hi Friends

I want to confirmed where selected face is Plane or Cylinderical type

I write code
                 FACE* ff=(FACE*)ent;
				 SURFACE* fs=ff->geometry();
				 if (fs->identity()==PLANE_TYPE)
				 {
				 AfxMessageBox("FACE is Plane Type");
				 }
but this error C2065: 'PLANE_TYPE' : undeclared identifier is comes out.

please tell me what should be done for it or which header file should
included

Thanks in advance
Ajit

hi ajit,


i usually use:

bool b = is_planar_face(ent);

with "ent" being of type ENTITY*...
hope this helps you. this way, you don't have to cast your entity to FACE*
and then to SURFACE*...


good luck,  irina

Subject: [Acis-alliance] Memory leaks
Message-ID: <[e-mail]>

When I start my application and quit it at once again, ACIS (compiled
with debug DLLs) produces a file called mmgr.log which starts with
*** Beginning Leak Dump ***
C:\build\acisr12\NTS\.\SPAlop\lop_husk_init.m\src\init_lop.cpp(62) :
{0000000071} at 0x0A6F2EA0 76 Bytes Type: 1 Call: 14
C:\build\acisr12\NTS\.\SPAblnd\blend_kernutil_init.m\src\initblnd.cpp(73)
: {0000000070} at 0x0A6F2D40 176 Bytes Type: 1 Call: 14
C:\build\acisr12\NTS\.\SPArem\rem_husk_remove.m\src\init_rem.cpp(52) :
{0000000069} at 0x0A6F2C70 32 Bytes Type: 1 Call: 14

(the whole 10KB file attached)
Is this normal? It sounds like my application is producing all these
memory leaks?
All I do in my application that's ACIS related is
in an init part:
  outcome a_return;
  a_return = api_start_modeller(0);
  a_return = api_initialize_faceter();
  a_return = api_initialize_constructors();
  a_return = api_initialize_booleans();
  a_return = api_initialize_intersectors();

and in the destructor
  api_terminate_intersectors();
  api_terminate_booleans();
  api_terminate_constructors();
  api_terminate_faceter();
  api_stop_modeller();

what's wrong with this and how are the memory leaks generated?

thanks a lot for your help,
Hannes

I saw that 
api_start_modeller(0);
api_stop_modeller();

alone causes about 300KB of memory leak (see attached mmgr.log).
Can something be done about it?

Hi friends

I am using folloing code for getting value from screen possition
I am using view vector
unit_vector dir( 0, -2, 1.5 ), up( -1, 1, -1 );
for display

what should be valuse for

position origin(?,?,?);
vector normal(?,?,?);

const position* pln_origin=&origin;
const vector* pnl_normal=&normal;
position pt;
api_gi_pick_screen_position(pe,pln_origin,pnl_normal,pt);

thanks in advance

Message-ID: <[e-mail]>

Hello. I just installed ACIS on to my computer. I am using a windows XP
machine with VC++ as the compiler. I just got the software yesterday. I
have installed the ACIS s/w but I cannot figure out how to get it
started. 
 
This is a very simple and basic question, but I need some help with
that. 
 
I hope someone will take time off to help me get it started.
Thanks

Dear Friends

I am using following code for generation of threads on cylinderical shaft
But when i call  this function display of part is very slow and when i
display same part in wireframe it take long time.
also time for sweep operation is long.

Can anyone tell how to reduce time for this.

Thanks in advance.
