Using SetConstraints() in vb api

Hello,

 

In the below code, where Assembly is a IpfcAssembly assembled in parentAssembly, why would it return  "Object type mismatch" on the last line?

 

 

IpfcComponentFeat asmComp = (IpfcComponentFeat)parentAssembly
 .AssembleComponent((IpfcSolid)Assembly, null);

IpfcComponentConstraint constraint = (new CCpfcComponentConstraint())
 .Create((int)EpfcComponentConstraintType.EpfcASM_CONSTRAINT_DEF_PLACEMENT);

IpfcComponentConstraints constraints = new CpfcComponentConstraints();
constraints.Insert(constraints.Count, constraint);

asmComp.SetConstraints(constraints, null); <--- Error

 

 

Regards

Solved using pro toolkit:

ProAsmcompAssemble(ProAssemblyHandle, child.ToProSolid(), identity_matrix, &assemblyComp);
ProArrayAlloc(0, sizeof(ProAsmcompconstraint), 1,(ProArray*)&constraints);
ProAsmcompconstraintAlloc(&constraint);
ProAsmcompconstraintTypeSet(constraint, ProAsmcompConstrType::PRO_ASM_DEF_PLACEMENT);
ProArrayObjectAdd((ProArray*)&constraints, 0, 1, &constraint);
ProAsmcompConstraintsSet(NULL,&assemblyComp, constraints);

And making sure that the subassembly has default csys and datum planes.

I've tested the solution using otk and pro toolkit, with the same issue but on a different place. Now on GetConstraints instead

 

 

OtkAssemblyHandle->AssembleComponent(child.ToOtkSolid(), NULL);
pfcComponentConstraint_ptr constraint = pfcComponentConstraint::Create(pfcComponentConstraintType::pfcASM_CONSTRAINT_DEF_PLACEMENT);

pfcComponentConstraints_ptr constraints = child.ToOtkCompFeat()->GetConstraints(); <-- XtypeMismatch
constraints->set(0,constraint);
child.ToOtkCompFeat()->SetConstraints(constraints,NULL);

 

 

So there sees to be some logic I'm unaware of.
