Does anyone know how to flatten a placed instance in magic?

It was supposed to be `select pick ; select flat ; select keep` , but I just tried that and the flattened selection vanishes on the last command, so I need to go figure out what's up with that.  Seems to be an error with the `select flat` command.

This method works, but is kind of awkward: `tech unlock * ; select cell ; select area ; copy n 0 ; select cell ; delete`.  The `select area` may pick up material outside of the cell being flattened this way.

Thanks. This is what I recommended, but may not select the get the locked layers. <https://skywater-pdk.slack.com/archives/C016UL7AQ73/p1645002619643109?thread_ts=1644990516.122249&amp;cid=C016UL7AQ73>

Interestingly, the following hack works:  `tech unlock * ; select cell ; select pick ; select flat ; move e 0 ; undo ; select keep`.  In other words, `select flat` puts it into some weird state, but then running a command and undoing it gets it out of that state.  That should be enough information for me to debug from.

<@U017X0NM2E7>:  Found and fixed.  The `select flat` command did not recompute the selection bounding box, which meant that the only thing that was seen in the selection during a search was whatever was in the unit area (0, 0) to (1, 1).  After the fix, the following sequence of commands will do a "flatten in place":  `tech unlock * ; select cell ; select pick ; select flat ; select keep` .

Thanks for the quick response. Sounds like a good candidate for a macro.
In program help says that `select pick` deletes the selection from the layout. Is this like ctrl-X in windows, i.e. delete and save to something like a clipboard?
