Command Term to Affix the Position of Related Components [message #168199] Wed, 04 January 2017 06:32 Go to next message

I am looking for the proper term to be able to research the method in Eagle to "tie" the position of two, or more, components to each other. (I am not talking about locking the position of components to the board.) When positioning a component, I want its related components to stay together with it, even if the related components are not captured by using the group function.

Often, drawing programs, such as Open Office Draw, have a "group" function to affix related components to each other. When you highlight any member of the group to move it, the entire group is moved. I want to know if Eagle has this functionality and, if so, what it is called, so I can research how to use it.

An example of this application would be a circuit having two different ICs, each requiring a decoupling capacitor on its power supply pin. No matter how I orient these two ICs, one to the other, I want their decoupling caps to move with its IC and always stay positioned next to its proper power pin.

Presently, in Eagle, I must remember to use the group function to capture the cap with its IC, when moving the IC. This becomes increasingly complicated, once the number of related components grows. And, sometimes, if a "community" of related components is not rectangular in shape and is intermingled with other components, you can not fish out a single community, to move it.

I am most willing to do my "homework," so please don't tell me to read the manual. I just need to know the term to look up. Thank you for your help.

Unfortunately EAGLE doesn't allow you to do this although I agree it would be very useful if it could.

The group function within EAGLE isn't restricted to drawing rectangular group areas. You can single click individual points of an arbitrary shaped group and then double click close to the initial point to close the group and add all the components to it. You can then do your group move. It's not ideal, it would be nice to be able to lock related groups of components together in the layout.

Best regards,
