Hi everyone, I'm tryng to modify the angle of a plane with the function ModifyDefinition but it returns false as i try to update the value.

I double checked everything in the code and i dont see any errors.

public void SetSlopeIndicationPlane(string assemblyName, SWPartDescriptor guide3D, dynamic slope)
{

   AssemblyDoc assembly = (AssemblyDoc)ActivateDoc(assemblyName);

 
Component2 guide = assembly.GetComponentByName(guide3D.PartName
