Problem with solid->extrudeAlongPath(region,path)

[Anonymous]

Hi there,

I have a big problem with the AcDb3dSolid memberfunktion : extrudeAlongPath.
My Application WORKS if I use solid->extrude(region,height,0.0)
But when I use solid->extrudeAlongPath(region,path) AutoCAD crashes.

So the Error has something to do with the "const AcDbCurve* path"

***********************************************************************
virtual Acad::ErrorStatus extrudeAlongPath(const AcDbRegion* region,const
AcDbCurve* path);
region Input pointer to a region object
path Input pointer to a curve object to extrude along´
************************************************************************


Here my code fragments:

AcDbArc Arc;
Arc.setNormal(AcGeVector3d(1.0,0.0,0.0));
Arc.setCenter(AcGePoint3d(0,200,0));
Arc.setStartAngle(PI2);
Arc.setEndAngle(PI);
Arc.setRadius(200);

AcDbCurve* path=&Arc; // I think here is the Problem !

AcDb3dSolid* solid = new AcDb3dSolid();

// extrude the region
////////////////// extrude(region,200,0.0); WORKS
solid->extrudeAlongPath(region,path); ////// ERROR
pBlockTableRec->appendAcDbEntity(ObjId,solid);
solid->close();

Thank you
David

Hi David,

The path must be a database resident entity, otherwise extrudeAlongPath()
will fail. DevNote 37173 - Creating and modifying AcDb3dSolid objects (on
ADN website and PointA Customization Channel) includes some sample code for
using this function.
