 * Avoid attaching sketches and datum objects to generated geometry of the model. (Generated geometry is any face or edge created as a result of a pad, pocket, etc..)
 * Place your sketches on standard coordinate planes, or on custom datum planes attached to standard planes.
 * Sketches attached to basic coordinate planes/axes or to datum planes attached to coordinate planes/axes, will not get unexpectedly reattached to a different reference.
 * When creating datum geometry, do not attach it to generated geometry
 * Attach it to standard planes/axes and/or sketches or datum objects which use attachment offsets to standard planes/axes.
 * Use a "master sketch". Since a master sketch is done before rest of the model, it only references the coordinate planes/axes.
 * A master sketch should be as simple as possible, containing basic geometric elements of your model.
 * Master sketch elements can be referenced when modelling subsequent features.
 * A master sketch can be the first sketch in the Body, or outside the body completely
 * A master sketch can be referenced as external geometry or via a ShapeBinder.
 * Don't create ShapeBinders from generated geometry
 * Keep in mind that ShapeBinders can be an issue when geometry is deleted from the sketch it is based on.
 * If you inevitably have to reference an intermediate feature, e.g. the result of a thickness operation
 * Use the first reference possible in the list of subsequent features where the referenced geometric element occurs.
 * If you take an early feature as reference, all changes to intermediate steps won't break your model.
 * Try to reference a sketch or sketch geometry rather than generated geometry.
 * Use dress ups, like fillets and chamfers, as late in the feature tree as possible
 * Note, using spreadsheets, dynamic data, master sketches, etc. generally produce more parametric models and help avoid the topological naming issue.
