Check If SOLID3D Has Valid Shape Manger Object

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;
