“In Creo Parametric 2.0, new drag handles adjust just the related dimensions, and not any linked dimensions; this carries out automatic parametric unlocking. Hold down Alt to select to geometry with which to reference a constraint, such as parallel to an edge. While assembling components, the 3D dragger will limit dragging to respect degrees of constraint as assembly constraints are applied. For example, a concentric constraint allows a part to be dragged only along the axis. When you choose an edge or a face, a rectangle pops up with data about the feature. You can copy and paste the data, and then use it to build a parameter, meaning, design intent. (This feature was always available, but was hidden deep in the old menu system.)”
