How to change Angle Constraint in Assembly?

[Articles]

I got a problem with editing angle constraint in assemblies. I tried edit property of constraint but it didn't move model. Simply changing Angle attribute of constraint item don't work.

Only way I achieved movemenet is

if(oOccurrence.Constraints[i].Name.Equals(name)){
         AngleConstraint a = (AngleConstraint)oOccurrence.Constraints[i];
         Object oEntity1 = a.EntityOne;
         Object oEntity2 = a.EntityTwo;
         String sVal = "" + angle + " deg";
         a.Delete();
         AngleConstraint d=oAsmCompDef.Constraints.AddAngleConstraint(oEntity1, oEntity2, sVal);
         d.Name = name;
       }

but this is really slow, as much as changing throught parameter:

if (assemblyDoc.ComponentDefinition.Parameters[i].Name == "d655")
{
Inventor.Parameter invParam = assemblyDoc.ComponentDefinition.Parameters[i];
invParam.Value = Math.PI * angle/180;
inventorApplication.ActiveDocument.Update();
}

Can someone help me with a quicker method?

Hi,

to drive assembly constraint, you need to use the methods of DriveConstraintSettings. Please refer to this post:
