How to remove the profile to revolve after forming the Revolved solid.

By Madhukar Moogala

Sometime back I have received a query from an ADN partner about

“After using AcDb3dSolid::createRevolvedSolid(), the revolved curve is visible in solid.”

The profile used to create Revolve appears in the solid, as shown in the snapshot.

This can be removed using cleanBody api of AcDb3dSolid, it removes all edges and faces not necessary to support the topology of the solid.

C++ Code:

void createSolid()
{
    double PI_VALUE = 4.0 * atan(1.0);
    AcGePoint2dArray pointArray;
    pointArray.append(AcGePoint2d(10.0, 0.0));
    pointArray.append(AcGePoint2d(15.0, 0.0));
    pointArray.append(AcGePoint2d(16.0, 2.0));
    pointArray.append(AcGePoint2d(16.0, 10.0));
    pointArray.append(AcGePoint2d(10.0, 10.0));
    pointArray.append(AcGePoint2d(10.0, 0.0));
 
    AcDbPolyline* pPline = new AcDbPolyline();
    for (int i = 0; i < pointArray.length(); i++)
    {
        pPline->addVertexAt(i, pointArray[i]);
    }
 
    AcDbRevolveOptions revolveOptions;
    AcDb3dSolid* pSolid = new AcDb3dSolid();
    if (eOkVerify(pSolid->createRevolvedSolid(pPline,
                    AcGePoint3d::kOrigin,
                    AcGeVector3d::kYAxis,
                    2.0 * PI_VALUE,
                    0.0, revolveOptions)))
    {
    /*Removes all edges and faces not necessary to 
    support the topology of the solid.*/
    if(eOkVerify(pSolid->cleanBody()))
    {
        AcDbObjectId objId;
        AcDbDatabase* pcurDb =
acdbHostApplicationServices()->workingDatabase();
        postToDatabase(pcurDb,
                        pSolid,
                        objId);
    }
 
    }
    delete pSolid;
    pSolid =NULL;
    return;
}
