I am a new learner in studying cad developing,my supervisor asked me to develp a small net programming about importing a text file covering dozen of points' Xdata,Ydata and Zdata to cad and create a polyline automatically. It means that we don't need to input point's coordination one by one to create a pline,we just to input a txt.file from the computer and a polyline will be drawed.

//If I right understood, maybe it helps:

//A kind of code to read from a (text) file:

FILE *stream;

char ch;

CString sztext, bufy;

int ix;

CString szFile = CString("dataintrare.txt");

/ Open for read (will fail if file "data" does not exist)

if( (stream = fopen( "dataintrare.txt", "r" )) == NULL )

printf( "The file 'dataintrare.txt' was not opened\n" );

else

printf( "The file 'dataintrare.txt' was opened\n" );

bufy = "The file " + szFile + " was opend\n";

AfxMessageBox(bufy);

while(!(feof(stream)))

{

[exceptions code …]

char ch;

CString sztext;

int ix;

sztext.Empty();

ch =fgetc( stream);

ix = sztext.Insert(0,ch);

if (sztext == CString("pct"))//sp)

{

ch =fgetc(stream);

ix = sztext.Insert(12,ch);

//[code to put the CString into your variable & exceptions…]

}

[code …]

}

// … For to the a/m variables into Autocad points, tha’s a different job
