Datum drawing3/18/2023 The Y14.5 standard shows several ways the material condition (Rule #2) default can be overridden. On the bracket drawing, there is one example where condition default applies it is labeled with balloon #5. It states "Rule #2- RFS applies to the individual tolerance, and RMB applies, with respect to the individual datum feature reference, where no modifying symbol is specified". This section explains what I call the "material condition default." This default is from paragraph 2.8. Without Rule #!, the form deviation of a feature of size could impact its overall size boundary and create an interference condition with the mating part. The size envelope (Rule #1) default is important because it creates an envelope boundary that ensures parts will assemble.
