Check If SOLID3D Has Valid Shape Manger Object

<?xml encoding=”UTF-8″>By Madhukar Moogala

Having Solid’s with invalid shape manager object is always prone to fatal crash it is suggested to check the sanity of underlying shape manager object for a given AcDb3dSolid.

You can check using SOLIDEDIT command.

;51 is Handle of the solid entity
(command "._solidedit" "B" "C" "51" "X" "X")

With API

Acad::ErrorStatus selectEntity(AcDbObjectId& eId)
{
ads_name en;
ads_point pt;
ads_entsel(_T("nSelect an entity: "), en, pt);
return acdbGetObjectId(eId, en);
}
void solidCheckForValidASM()
{
AcDbObjectId solId = AcDbObjectId::kNull;
if (!eOkVerify(selectEntity(solId))) return;
AcDbSmartObjectPointer pSolid(solId, AcDb::kForRead);
if (!eOkVerify(pSolid.openStatus())) return;
//Get access underlying raw pointer
if (nullptr == pSolid.object()) return;
std::unique_ptr pEnt(new AcBrBrep());
//pass raw pointer to BREP API
if(pEnt->set(*pSolid.object())!= AcBr::eOk) return;
bool isGoodAsmBody = pEnt->checkEntity();
if (!isGoodAsmBody)
{
acedAlert(_T("Null or Invalid Shape Manager"));
}
return;
}
