Mark, If you export a sub-drawing it's a copy of components and etch into one file. You have the choice of preserving ref des's into the clip file or not. It's a way of doing in one step what you do in two separate steps. If you use a temp group it gives you the ability to select certain etch and components that you want to preserve. You can then import the sub-design into a different board. even edit the sub-drawing file if you wish to change ref des's. Look under file->import and file ->export for this command.

Matching ref des will keep their original placement. OR...Bring in the placement through place.txt of only the components to be cloned. Then clip in traces if necessary. Charles, As I mentioned, the GROUP property is also hard to manage. How do you keep track of which ones were used? We have not tried "sub-design" or "design reuse". Maybe it is time? We have also been avoiding hierarchical schematics due to other issues. regards, Mark gnieski_mike@xxxxxxx wrote: >What if you hard located only the ref des that you are cloning >placement on and leave the rest soft located?
