Geometric Dimensioning and Tolerancing: Applications and Techniques for Use in Design, Manufacturing, and Inspection
by James D. Meadows
It more of a "textbook" than Foster's book but gives some very detailed explanations of GD&T concepts as well as some examples that aren't found in either...
If the 12 holes are a rectangular pattern and A, B and C are surface datums, then the lower frame shouldn't really have a C specified. In this case, to verify the upper frame, the center axis of the hole must be within 1.25 as established by the basic dimension from the datums. Typically, one...
For a composite feature control frame, the lower segment controls the feature-to-feature tolerance and the basic dimensions relating the pattern to the datums do not apply. Therefore the lower segmnet can have no datum reference or may repeat, in the same order of precedence, some or all of the...
Actually, its the other way around. The top controls the pattern location (PLTZF - Pattern-Locating Tolerance Zone Framework) and the bottom controls the features within the pattern (FRTZF - Feature-Relating Tolerance Zone Framework)

Just drag the part from the subassembly to the top-level assembly - no alt, ctrl, shift, etc. - and you should see the black diagonal, "2 way" arrows (very first item in the feature tree). This should move the part and preserve its mates, at least it does in SW2005 SP2.0.
The only issue I've...
We had the same issue on a number of our workstations all running XP SP1, SW2005 SP2.0. Whenever we opened the sldworks.chm help file (and a few others as well) we encountered the Explorer scripte error "Object dosent support the property or method." We finally tracked the problem back to the...
