Synchronous design problems
Synchronous design problems
(OP)
Call me a luddite but I have never got to grips with synchroneous design.
Building the part is no problem it is trying to add constraints and dimension the part. I have no idea if a part can modified by a dimension or how it will behave when I do so. Do all faces lines and vertices have to be explicitly constrained?
Is synchreneous design extensively used and what are it's advantages?

RE: Synchronous design problems
Live Rules - Used to dynamically relate those common face orientations one would logically "assume" like adjacent faces remaining Perpendicular in a rectangular box or a series of holes remaining in a line. These can be tailored to suit the desired change if there is an exception to this "logical" assumption.
Face Relations - Used to temporarily make two or more faces re-orient to each other, or it can be made a "persistent" relationship. Example... Make one face parallel to another. By default it is temporary but can optionally be made to "persist".
Locked Dimension - Dimensions by default are not locked and thus will either temporarily move geometry to a location that you type in or allow you to dynamically move a face and they will update with the new value. A Locked dimension will permanently remain the value specified until your type in a new value.
In my mind, the best practice would be to decide what things are critical to the design and lock those down with persistent face relations and locked dims and leave the rest to live rules, but you REALLY need to think about what is CRITICAL because it is easy to say "everything" but in reality it's just a few things.
