Subject: [Acis-alliance] qtacishoopsrefapp doesn't work
Message-ID: <[e-mail]>

Hi,
i need to build an application using ACIS 13 HOOPS 11.1 and QT 3.3.1.
After some searching i found the qtacishoopsrefapp.zip:
http://developer.hoops3d.com/downloads/DevZoneSamples/qtacishoopsrefapp.zip 
I hoped that this is a good entry point for my work.
I'm able to compile it and the HOOPs part is also working  (drawing spheres,
coni, etc.)  
But whenever i want to load a SAT file a new Window is opened but only with
a black screen. no SAT BODY can be seen.
What i don't understand:
I've searched in the whole project for a api_initialize_hoops_acis_bridge
call but didn't find any. 
>From what I've learned in the ACIS manual concerning the HOOPS-ACIS Bridge
this initialization function has to be called.

Furthermore there is a 

"HA_Read_Sat_File(FileName, elist); // read an SAT file" 

statement in the code but it doesn't seem to be reached. 

My question: is this reference app really able to load and show sat files?

Subject: [Acis-alliance] incremental faceting
Message-ID: <[e-mail]>

Hello acis-alliance:
  I am wondering how to undergo the incremental faceting.when i use the function
api_facet_unfaceted_entity or api_facet_unfaceted_entities to facet a body,it does not perform as expected. The faceter still faceting all the faces on a body other than those faces that have changed since they were last faceted.I think it should be some wrong with my program,so could you please kindly tell me how to use these two functions correctly?
  my program is here:

  void main(){
	
	api_start_modeller(0);
	api_initialize_faceter();
	api_initialize_constructors();

	api_mark_faceted_faces(TRUE);
	BODY *cuboid;
	api_make_cuboid(100,100,100,cuboid);

         api_mark_faceted_faces(TRUE);
	My_INDEXED_MESH_MANAGER* MM1 =	new My_INDEXED_MESH_MANAGER();
         api_set_mesh_manager(MM1);

	VERTEX_TEMPLATE* tplate;
	int	ntokens = 2 ;
	int	token[2];
	token[ 0 ] = POSITION_TOKEN ;
	token[ 1 ] = NORMAL_TOKEN ;
	api_create_vertex_template( ntokens, token, tplate );
	api_set_default_vertex_template(tplate);

	REFINEMENT* ref = NULL;
	api_get_default_refinement(ref);

	ref->set_surface_tol(10);
	ref->set_normal_tol(10);
	ref->set_grid_aspect_ratio(1);
	ref->set_max_edge_length(10);
	ref->set_adjust_mode(AF_ADJUST_NONE);
	ref->set_grid_mode(AF_GRID_TO_EDGES);
	ref->set_max_grid_lines(300) ;
	ref->set_triang_mode(AF_TRIANG_ALL);

	api_set_default_refinement(ref);


         api_facet_unfaceted_entity(cuboid);
	api_mark_faceted_faces(TRUE);

	CString s1;
	s1.Format("cnt1:%d,cnt2:%d,cnt3:%d,\ncnt4:%d,cnt5:%d,cnt6:%d,\ncnt7:%  d,cnt8:%d,cnt9:%d",
		cnt1,cnt2,cnt3,cnt4,cnt5,cnt6,cnt7,cnt8,cnt9);
		 AfxMessageBox(s1);

	cnt1=0,cnt2=0,cnt3=0,cnt4=0,cnt5=0,cnt6=0,cnt7=0,cnt8=0,cnt9=0;
	My_INDEXED_MESH_MANAGER* MM2 =	new My_INDEXED_MESH_MANAGER();
    api_set_mesh_manager(MM2);

	api_initialize_blending();
	EDGE *edge=cuboid->lump()->shell()->face()->loop()->start()->edge();
	ENTITY_LIST edgelist;
	edgelist.add(edge);
	api_blend_edges(edgelist,20);

	api_facet_unfaceted_entity(cuboid);
	
	CString s2;
	s2.Format("cnt1:%d,cnt2:%d,cnt3:%d,\ncnt4:%d,cnt5:%d,cnt6:%d,\ncnt7:%d,cnt8:%d,cnt9:%d",
		cnt1,cnt2,cnt3,cnt4,cnt5,cnt6,cnt7,cnt8,cnt9);
		 AfxMessageBox(s2);

    delete MM1;
	delete MM2;
	api_terminate_blending();
	api_terminate_constructors();
	api_terminate_faceter();
	api_stop_modeller();
}

My_INDEXED_MESH_MANAGER is a class that i derived from INDEXED_MESH_MANAGER. cnt1,cnt2,....,cnt9 are some counters to indicate how many times the functions in the mash manager have been called when faceting the cuboid.

Subject: [Acis-alliance] Parametric modelling in ACIS
Message-ID: <[e-mail]>

Hi,
    I am working with acisR10sp9.I followed the managed history streams example given in the september 2004 archives.I am practising an example for parametric modelling in ACIS.I am able to roll back to previous state from current state using api_changed_state.But I am unable to change the state further.What I have done is created a solid block,frustum and subtracted frustum from solid block and then rolled back to frustum  state and deleted the old frustum and created new frustum.What I need is would like to roll forward to subtracted state and that frustum need to be changed after forward.Here below i am giving  the code.

I will respond to your message when I return (perhaps sooner if the

Message-ID: <[e-mail]>

Dear Markus，

On the problem you stated, I suppose this is due to incorrect version of SAT file. Where is your SAT from? Say it is exported from tertiary CAD packages, make sure that you export the entities with ACIS V11.0 or ACIS 12.0 version, else you can see nothing in the canvas. So far with ACIS R13 SP9, you can not sucessfully read ACISr13 SAT files, I did tried this in Solidworks. Hope this helps.
