Subject: [Acis-alliance] question about using BinaryFile
Message-ID: <[e-mail]>

Hi! all

I made a derived class 'FileSizeComputer' from 'BinaryFile' and tried to
use it as the first argument for 'save_entity_list_on_file(FileInterface*,
ENTITY_LIST const&)' function like follows.

-----------------------------------------------------------
FileSizeCompute file_size_computer;
save_entity_list_on_file(&file_size_computer, entity_list);
-----------------------------------------------------------

However, I got an error sign when I execute the code as follows.
 
-----------------------------------------------------------
*** Error (kernel/kerndata/savres:BAD_UNITS)
    could not save, the units in Fileinfo must be valid
    Aborting program
-----------------------------------------------------------

I think I have to give a valid FileInfo object to my 'FileSizeComputer' but I
don't know how to.
Is there anybody to know about this?
Thank you.

First, I notice you are calling an internal function
save_entity_list_on_file instead of an api function
api_save_entity_list_on_file.  This accounts for the system aborting your
program instead of catching the exception and returning an error code.
There are techniques for avoiding this, but generally it is best to stick
with api's where possible.

Second, there is a pair of api's, api_set_file_info and api_get_file_info.
This is likely the source of your BAD_UNITS problem.  The defaults should be
good, but you may want to look into explicitly setting this stuff.

    1. Declare a FileInfo local var.
        a) Call FileInfo::set_product_id().
        b) Call FileInfo::set_units().
    2. Call api_set_file_info(), and pass your FileInfo.

    Then your api_save_*() will work.

    Alternatively, if you just read a file, and you want to write to
    the file using its same FileInfo data, call api_get_file_info()
    to get the current FileInfo, and pass that to api_set_file_info().

Subject: [Acis-alliance] Splitting an EDGE on a body
Message-ID: <[e-mail]>

This message is in MIME format. Since your mail reader does not understand

Content-Type: text/plain;
	charset="iso-8859-1"

I am trying to split an edge on a BODY (a sheet BODY in this case).  I do
not want to change the geometry of the BODY, but I want a connected VERTEX
at the split position.  I have tried:

api_split_curve - returns an error because it is not prepared to split an
EDGE owned by a BODY.

create a point BODY (degenerate wire body with one vertex) and imprint it on
the sheet BODY.  This apparently fails because imprint is not prepared to
deal with a degenerate wire.

I am planning to try using an imprint with a disk (api_make_planar_disk) and
then clean up the body, but this seems more complicated than it needs to be.
Is there something else obvious that I am missing?

Thank you for any assistance,

Alan

Subject: [Acis-alliance] copy of a surface
Message-ID: <[e-mail]>

Hello!

Does anybody know any functions in ACIS that can make a copy of a
surface (FACE)?
In my application, i first built a BODY and pick some of the FACEs of
the BODY; then i want to make a FACE that has the same shape and
location of each of the FACEs i picked (basically, i need to make a copy
of each of the FACEs.) And finally i delete the BODY.

Could anybody out there help? Thanks a lot.

Shen

    product_id:
    - Use any text string.
       Usually, you write the name and version of your own application,
       so that you can identify your own .sat files later.
       But any string is OK.

    units:
    - This is the scale factor from your internal numbers to mm.
       1.0 means your 1 = 1mm.

        You generally want to keep your dimension numbers in the
        "good" floating-point range of roughly [1E0, 1E5], for best
        numerical accuracy.  (See past posts by Arlo Ames for the
        details.)  If you're modeling physical parts, 1mm is a reasonable
        size.  If you're modeling huge things like a bridge or a submarine,
        then units of 1000 (= 1m) would be more appropriate.  So it
        depends on your application domain.

    api_sheet_from_ff().

    This copies 1 FACE, then inserts it into a new BODY, and returns
    that.  The result is a "sheet body", which consists of only this 1 FACE.
    That's usually more useful than having a copy of a FACE, since most
    ACIS operations expect a BODY as input, not a dangling FACE.

Subject: [Acis-alliance] EDGE-FACE intersection
Message-ID: <[e-mail]>

Hello Acis-Alliance,

I have a problem:
I want to intersect an EDGE (geometry is a straight line) with a FACE
(geometry is a spline surface).
Here is a part of the code for generating the EDGE and the intersection with
the existing spline FACE:

		EDGE *cutedge;
		api_curve_line(start, end, cutedge);
		savelist->add(cutedge);
		api_make_edge_from_curve(cutvector->equation, cutedge);

		// intersect edge with face to find
vertex...................................................
		ENTITY_LIST* cutvert;		// usually one entity, the vertex
		ENTITY *po_face; 		// the vertex on the face (as ENTITY)
		VERTEX *vo_face;		// the vertex on the face (as VERTEX)
		outcome res = api_edfa_int(cutedge, splineface, cutvert);
		outcome_check(res, "Error in API call");		// check the outcome
		cout << "PAMFACE: " << i << endl;
		if (cutvert->count() !=1)
		{
			if (cutvert->count() > 1)
			{
				cout << "Error in quad " << i << ": more than 1 cutvertex found.\n";
			}
			else if (cutvert->count() < 1)
			{
				cout << "Error in quad " << i << ": no cutvertex found.\n";
			}
		}
		cutvert->init();
		po_face = cutvert->next();
		if (is_VERTEX(po_face))
		{
			vo_face = (VERTEX*) po_face;
		}
		else if (!is_VERTEX(po_face))
		{
			cout << "Error in quad "<< i << ": ENTITY found is not a VERTEX.\n";
		}


In the debugger it throws an error for the call of 'api_edfa_int(...' as
follows:
