BRepAlgoAPI_Cut Problems

Error in this: "TopoDS_Shape Cut = BRepAlgoAPI_Cut(aBaseBox,aHoleCyl);"

"aBaseBox" and "aHoleCyl" is "AIS_Shape", but must be a "TopoDS_Shape".
You must use yors "B" from "BRepPrimAPI_MakeBox" and "BRepPrimAPI_MakeCylinder".

Sample:

BRepPrimAPI_MakeBox myBox(gp_Pnt(Dlg.m_x, Dlg.m_y, Dlg.m_z), Dlg.m_w, Dlg.m_l, Dlg.m_h);
BRepPrimAPI_MakeCylinder myCyl(((Dlg.m_x, Dlg.m_y, Dlg.m_z),(Dlg.m_x1, Dlg.m_y1, Dlg.m_z1)), Dlg.m_h, Dlg.m_r);

TopoDS_Shape Cut = BRepAlgoAPI_Cut(myBox, myCyl);

Appreciate for your advise. Unluckly, there is the same error message when I rebuild it.
Attached is the .cpp file.

I do not compile your file. It's big and may contain more than one error with Cut operation :)

So, I wrote a working sample for you. Try this:
////////////////
// vars
Standard_Real cylRadius = 15.;
Standard_Real cylH = 150.;

Standard_Real boxL = 100.;
Standard_Real boxW = 80.;
Standard_Real boxH = 50.;

TopoDS_Shape resultBox;

// make Box
BRepPrimAPI_MakeBox myBox( gp_Pnt( 0, 0, 0 ), boxL, boxW, boxH );

// make axis of direction for cylinder
gp_Ax2 cylAx2(gp_Pnt( 50, 50, 0 ), gp_Dir( gp_Vec( gp_Pnt(0,0,0), gp_Pnt(0,0,100) ) ) );

// make cylinder
BRepPrimAPI_MakeCylinder myCyl( cylAx2, cylRadius, cylH );

// make Cut operation and get result
resultBox = BRepAlgoAPI_Cut( myBox, myCyl.Shape() );

// show myBox
Handle(AIS_Shape) myBoxAIS = new AIS_Shape( myBox );
myAISContext->SetColor( myBoxAIS, Quantity_NOC_RED );
myAISContext->SetMaterial( myBoxAIS, Graphic3d_NOM_SHINY_PLASTIC );
myAISContext->SetDisplayMode( myBoxAIS, AIS_Shaded );
myAISContext->SetCurrentObject( myBoxAIS, Standard_True);
myAISContext->Display( myBoxAIS );

// wait
Sleep(1500);

// show myCyl
Handle(AIS_Shape) myCylAIS = new AIS_Shape( myCyl );
myAISContext->SetColor( myCylAIS, Quantity_NOC_GREEN );
myAISContext->SetMaterial( myCylAIS, Graphic3d_NOM_SHINY_PLASTIC );
myAISContext->SetDisplayMode( myCylAIS, AIS_Shaded );
myAISContext->SetCurrentObject( myCylAIS, Standard_True);
myAISContext->Display( myCylAIS );

// wait
Sleep(1500);

// delete objects
myAISContext->Erase( myBoxAIS );
myAISContext->Erase( myCylAIS );

// show result of Cut
Handle(AIS_Shape) resultBoxAIS = new AIS_Shape( resultBox );
myAISContext->SetColor( resultBoxAIS, Quantity_NOC_MATRABLUE );
myAISContext->SetMaterial( resultBoxAIS, Graphic3d_NOM_SHINY_PLASTIC );
myAISContext->SetDisplayMode( resultBoxAIS, AIS_Shaded );
myAISContext->SetCurrentObject( resultBoxAIS, Standard_True);
myAISContext->Display( resultBoxAIS );

// THE END

Thanks for your kindly help. My programe's condition is creating the box and cylinder in two functions, and cut function is in the made cylinder function; consider that the BRepAlgoAPI_Cut could not identify the handle box,so I define the handle of the box. I don't know whether it is available or not.

If you want use 2 functions, you must define "TopoDS_Shape myBox" in global section.
For example in "*.h" file:

....
private:
TopoDS_Shape myBox;
....

And then use it in your functions. Or, you may use function which returns a TopoDS_Shape and use this function in other functions. Example:

TopoDS_Shape MyClass::getMyBox()
{
...
TopoDS_Shape box = BRepPrimAPI_MakeBox(gp_Pnt(Dlg.m_x, Dlg.m_y, Dlg.m_z), Dlg.m_w, Dlg.m_l, Dlg.m_h);

return box;
}

void MyClass::someFunction()
{
...
resultBox = BRepAlgoAPI_Cut( getMyBox(), myCyl.Shape() );

}

sorry to reply too late. I tried your method.But there are errors on defined "TopoDS_Shape MyClass::getMyBox()",the error is :
overloaded function differs only by return type from 'void CSampleViewer3dDoc::OnBaseBox(void)

I think the problem can be simplied as :how BRepAlgoAPI_Cut can transfer the box which in getMyBox()?

Did you rename "MyClass" to your class's name like "CSampleViewer3dDoc"?
You make some errors in class construction. Please read chapter "Object Oriented Programming" on http://www.cplusplus.com/doc/tutorial/

Yeah, I'm sure.But there is an error:
'TopoDS_Shape CSampleViewer3dDoc::OnBaseBox(void)' : overloaded function differs only by return type from 'void CSampleViewer3dDoc::OnBaseBox(void)'
May I get your msn and have a chat online? My msn:[email removed]
Appreciate for your help.

I don't have msn. You can contact with me by using Jabber, ICQ, or Skype.

Also check your "*.h" file for definition of "OnBaseBox(void)" function. You must have in class "CSampleViewer3dDoc" this definition:

// in includes
#include

// in your "*.h" file where class's functions is.
TopoDS_Shape OnBaseBox(void);

I think, error happens because you have definition like this:

void OnBaseBox(void);

but must be "TopoDS_Shape OnBaseBox(void);".
