What was my mistake ?  Is there anybody to know about this?

Your help would be appreciated.

I was wondering if anyone knew how to go about exporting sat files to other pieces of software. For example there is an import sat function in cad R14 but when i try to open a sat file nothing happens. Any help in this area would be much appreciated.

Thanks,

Subject: [Acis-alliance] api_entity_point_distance  and edge problem
Message-ID: <[e-mail]>

hi all,

I use ACIS 8.0 and have the following problem with the 
api_entity_point_distance  function:

I create a BODY just containing one EDGE:
EDGE *line;
bs3_curve spline = ...;
api_mk_ed_bs3_curve ( spline, line );
COEDGE *co = new COEDGE( line, FALSE, NULL, NULL );
WIRE *wr = new WIRE( co, NULL );
BODY *bd = new BODY( wr );

then I want to get a point distance (for picking) using this

api_entity_point_distance (
	bd,			// entity
	rayPnt,			// point
	closest_pos,		// position on entity
	distance		// distance value
);

but the distance I get is invalid.
if I directly give the EDGE it works:

api_entity_point_distance (
	line,			// entity
	rayPnt,			// point
	closest_pos,		// position on entity
	distance		// distance value
);

does anybody know what I'm doing wrong?

thanks a lot.

Timo

I think the problem may be that your are connecting the WIRE* directly to
the BODY.  BODY has a WIRE*, but that is only for upward compatibility.  The
WIRE is supposed to be connected to a SHELL, which should be connected to a
LUMP which is connected to the BODY.  It is possible that
api_entity_point_distance does not recognize the legacy configuration.

Hi, all:

I am using Scheme to create a CAD model of helical pinion.  I got the =
cross section of one tooth that includes four edges, two involute curves =
and two circular curves.  I combined them as a wire-body and then tried =
to use sweep:law to extrude the cross section.  But I always got a error =
message that says "Error sweep:law: Float divide by zero".  I even could =
not do a straight extrusion.  Is there any mistake I made?  Was it =
because that the four curved edges are not tangent to each other?  How =
to fix this problem?

I am urgently waiting for replies.  Your help will be highly =
appreciated.  Thanks in advance.

Haiyan Deng
