we use the following code to display a B-Spline edge as a PolyCylinder, and use the function HC_Move_By_Key(...) to highlight the PolyCylinder when we select it. but we find when nMax > 25, the memory used by the application programe increases dramatically when we select the PolyCylinder and highlight it.
/**********************************************************
//pEdge is a B-Spline edge
const int nMax = 20;
float fRadii = 0.1;
double dTolerance = 0.01;
double dStartParam = pEdge->start_param();
double dEndParam = pEdge->end_param();
int nPoints= 0;
double dParam[nMax];
SPAposition sPts[nMax];
HPoint hPts[nMax];
api_facet_curve(pEdge->geometry()->equation(), dStartParam, dEndParam,
dTolerance, nMax,nPoints, sPts, dParam ) ;
nPoints = min(nMax,nPoints);
for ( int i=0; i<nPoints; i++ )
{
hPts[i].Set( sPts[i].x(), sPts[i].y(), sPts[i].z() );
}
HC_KEY key = HC_KInsert_PolyCylinder( nPoints, hPts, 1, &fRadii, "both" );
if(m_pHAMap)
m_pHAMap->AddMapping(key, pEntity);

how to fix the problem? is there anybody can help me?
thank you!
