how to use the saveas4 function

Dear all

i am new to the solidworks API...
currently i can draw a cylinder with the dll...and after the drawing i
want to save the part as STL format...
i looked into the API help file and found maybe saveas4 can be used.
but some errors when compiling...
cannot figure out where is the problems

void MenuItemCB(void)
{
LPMODELDOC pModelDoc;//define pModelDoc pointer
TheApplication->GetSWApp()->get_IActiveDoc(&pModelDoc);//obtain
pModelDoc pointer
LPPARTDOC pPartDoc;// define pPartDoc pointer
pModelDoc->QueryInterface(IID_IPartDoc,(LPVOID *)&pPartDoc);//obtain
pPartDoc pointer

VARIANT_BOOL retval;//define retval
pModelDoc->SelectByID(auT("Front"),auT("PLANE"),0,0,0,&retval);

pModelDoc->InsertSketch();//enter sketching drawing

double P1[3];// defind and evaluate p1 & p2
P1[0]=0;
P1[1]=0;
P1[2]=0;
double P2[3];
P2[0]=0;
P2[1]=0.1;
P2[2]=0;
pModelDoc->ICreateCenterLine ( P1, P2 );//draw the center line through
P1, P2
pModelDoc->ClearSelection();//clear selection

LPSKETCHSEGMENT retval2;//define retval2
pModelDoc->ICreateLine2 ( 0, 0, 0, 0.03, 0, 0, &retval2 );//draw line
pModelDoc->ICreateLine2 ( 0.03, 0, 0, 0.03, 0.09, 0, &retval2 );//draw
line
pModelDoc->ICreateLine2 ( 0.03, 0.09, 0, 0, 0.09, 0, &retval2);
pModelDoc->ICreateLine2 ( 0, 0.09, 0, 0, 0, 0, &retval2 );//draw line
pModelDoc->InsertSketch();//quit sketch

VARIANT_BOOL retvala;//define retvala
VARIANT_BOOL retvalb;//define retvalb
VARIANT_BOOL retvalc;//define retvalc
VARIANT_BOOL retvald;//define retvald
VARIANT_BOOL retvale;//define retvale
VARIANT_BOOL retvalf;


pModelDoc->SelectByID(auT("Line2"), auT("SKETCHSEGMENT"),0,
0,0,&retvala);//
pModelDoc->SelectByID(auT("Line3"), auT("SKETCHSEGMENT"),0,
0,0,&retvalb);
pModelDoc->SelectByID(auT("Line4"),
auT("SKETCHSEGMENT"),0,0,0,&retvalc);
pModelDoc->SelectByID(auT("Line5"),
auT("SKETCHSEGMENT"),0,0,0,&retvald);
pModelDoc->SelectByID(auT("Point2"),
auT("SKETCHPOINT"),0,0,0,&retvale); //


pPartDoc->FeatureRevolve (6.28318530718, 0, 0, 0);//

pModelDoc->BlankSketch ( );//
pModelDoc->ShowNamedView2(auT("*Isometric"),7);//
pModelDoc->ViewZoomtofit2();//

////////the above codes are used to draw the cylinder and clear the
sketch

pModelDoc->SaveAs4("Cylinder.stl", swSaveAsCurrentVersion,
swSaveAsOptions_SaveReferenced, &retvalf);
/////this want to be added to save the part as STL format...
but the compiling errors is that error C2039: 'SaveAs4' : is not a
member of 'IModelDoc'
what is the problem?
and also i am not sure if it is right to define the parameters in the
saveas4 as swSaveAsCurrentVersion, swSaveAsOptions_SaveReferenced,
&retvalf);

thanks for all the help

 

i am using visual C++6.0

 

Running a simple record macro that accomplishes largely the same thing,
SW auto inserts "Part.SaveAs2", which brings up a dialog box asking whether
to export the selected body, or all bodies. Once confirmed, the stl is
exported. Not having looked through the formatting for the command, it may
be possible to auto-set the option, so that one does not have to contend
with the dialog box.

according to one of google friends's reply, i used MODELDOC2 other than
MODELDOC, the problem solved...thanks so much
finally i used the function as below:
pModelDoc->SaveAs4(auT("D:\\Cylinder\\Cylinder.stl"), 0, 1, NULL, NULL,
&retvalf);

it works

thanks
