Subject: [Acis-alliance] semi-cylinder face
Message-ID: <[e-mail]>


Dear, all

   I am reading sat files(.sat) exported from Solidworks, in which a cylinder face is represented as two semi-cylinder faces. And I want to deal with them as the whole one. How can i judge whether two semi-cylinder faces belong to one cylinder face?  Does anybody do me a favor to give me some suggestions?

   Any ideas will be greatly appreciated!

Gao,

The two faces would have the same surface, and would share
two linear edges as coedges in opposite directions.

HTH,

Dear acis-alliance members,

  I want to make a solid transparent in view. I mean that I can see the inner part through the outer part. Should I use set-material first, and set the transparency of the material? 

Thank you

  Secondly, whether a cylinder surface is expressed by two faces? Why? If so, how to dicide which one of the two is belong the cylinder surface?

Thank you

Dear acis-alliance members,

  I have some questions as follows:
1.Which one is the address to send questions to? [e-mail] or [e-mail] . Somebody tell me to send questions to the latter. 
2.What is len()? For an example, double length=diagonal.len(); why should we use len()?
3.How to draw a coordinate system in screen(GUI)? 
4.How to construct a snap net in plane?

Thank you

Hi everyone,

I have compiled the following codes in scheme to split a cone. But it always notes "***Error let*: wrong number of grguments". What's wrong in the code? I can not find it. Any help will be appreciated.

           (cutter(sheet:planar-wire slicer-wire))
           (begin

Subject: [Acis-alliance] some questions on ACIS MFC
Message-ID: <014601c321f5$79b07f20$af501e0a@t6>

Hello everyone,

  I have some questions on ACIS MFC:
1. How to set wcs color? Should I use api_rh_set_entity_rgb? I know there are a function (env:set-active-wcs-color color=0 1 0) in scheme to set wcs color. But I can not find the relevant function in C++.
2. I have able to construct a grip net in a plane. How to realize mouse snap grip in ACIS MFC? For example, how to draw a rectangle on xy plane with mouse snap grip?

Thank you

Subject: [Acis-alliance] What is wrong in these scheme codes
Message-ID: <[e-mail]>

let* is expecting a list of variables with initializers.  The last open
paren
(let* (
just begins the declaration of the list.  I suspect the problem is more with
the 
(begin
and the
(entity::delete...)
forms.  The (begin... thing doesn't look like just a variable and its value
-- I think (I'm more lisper than schemer) that the begin begins a list of
program statements to be executed, and not a variable with its values.  So
the code should look like
 
(let *((var1 (function to init))
        (var2 (function to init var 2)
       )  /* ends variable declarations but not the let* */
     (begin
        (sheet::2d .....)))
 
If the begin is just being used to declare a list of function calls, I think
you can dispense with it.  At least in lisp, you can declare any number of
function calls within a let*, after the variables declaration part.
 
I don't think you intend to declare a variable with (entity::delete, but
rather to call entity's delete member function.  It can't occur in the
variables declaration part of the let*, but should occur after ward (maybe
just before entity::transform?).
 
And a question for somebody who does this oftener than I:  Is the variable
"cone" going to automatically delete itself when it falls out of scope
anyway?

Subject: [Acis-alliance] An  ACIS R10 question
Message-ID: <000c01c3275b$019b0670$af501e0a@t6>

Hi everyone,

  I have update my ACIS from R8 to R10. Under R8,I can realize the function of Grid On in an ACIS MFC by using the following codes:

void CMyAHAppView::OnGridOn() 
{
 // TODO: Add your command handler code here
 input_grid* the_grid= get_global_grid();
 rgb_color gridcolor(7);
 the_grid->set_display_color(gridcolor);
 the_grid->set_display_interval(5,5);
 the_grid->activate_snap(TRUE);
 the_grid->display(TRUE);
 
 CAcisDoc *p ;
 p = GetActiveAcisDoc() ;
 p->InvalidateViews() ; 
}
//-----------------------------------
But ACIS R10 has changed its architecture by reducing some folders. There are not gi,gl and amfc folders in ACIS R10. I have bulid a ACIS HOOPS MFC by using AHAppWizard. Now I want to realize Grid On. But I can not pass the compiling process by using the upper codes, because I can not locate some header files.
//-------------------------------
#include "gihusk/dl_ctx.hxx" // Add
#include "gl_husk/gl_ctx.hxx" // Add
#include "gihusk/grid_def.hxx"
#include "acismfc/amfc_utl.hxx" 
//-------------------------------
Who knows how to locate these header files? Thank you .
