Jami, You can restrict actions to certain entity types - so if you are moving designators you can set up a Move-String command (see the Move Process reference) - this dramatically helps in dense designs. The same is possible with pads, components, tracks etc. So if you are doing a lot of stuff on the same entity type setting up (or using the default commands) that restrict actions to specific entity types is often useful. As a check, I just tried to see if I could get a component primitive to move with the PCB:MoveObject|Object=Pad process and parameter. No go, the pad stayed fixed to the component. The only method I knew of moving a pad of a component with locked primitives is to edit the pads XY coords. Now I know another - some strange sequence of operations may cause it when moving/rotating a selection - at least that is what is seeming likely to me from Brad and Dennis's reports.
