Hi to All,

I have a problem about changing external referans position on master map.

I have crated new external referance and added succesfulluf to db but I’m unable to set right position

on master flt.

I think that I couldn't set transformation matrix on new node.

You can see the code below.

static mgbool set_pos (mgrec* db, mgrec* parent, mgrec* rec, void* userData)

{

mgrec* scale;

mgrec* translate;

mgmatrix matrix;

mgmatrix temp_matrix;

char formatString[50];

int fieldWidth = 8;

char* name = mgGetName (rec);

int val = mgGetCode(rec);

char *xref_model_filename;

int found;

if(val == eFltXref)

{

mgGetAttList(rec,

fltXrefFilename,&xref;_model_filename,

fltMatrix, temp_matrix,

mgNULL);

mgWalkGetMatrix (userData, &matrix;);

std::string path = xref_model_filename;

mgmatrix mymatrix_temp;

// Get current matrix

mgMatrixCopy(&mymatrix;_temp,matrix);

mgDelete (rec);

mgrec *xrec = mgNewRec(fltXref);

mgSetAttList(xrec,fltXrefFilename,path.c_str(),MG_NULL);

// Problem about setting thr transformation matrix

mgSetAttList(xrec,fltXmTranslate,mymatrix_temp,MG_NULL);

mgAttach(parent,xrec);

mgWriteDb(db);

}

This is a common question.
