Lock/Unlock line by command or api?

[George.Endrulat]

Looks asked and answered here: Line Lock in Batch - Autodesk Community - AutoCAD Plant 3D by @jabowabo both times, thanks for putting up with me being lazy.

I know you can lock/unlock using the data manager or isometric tab on the project palette.

I am trying to do an excel import that'll change a few hundred items and we're sitting at about 80% of 1,000 lines locked.  As you'd imagine, nearly every cell can't be changed because the line is locked.  It'd be sure useful to be able to macro/lisp/etc out a command alias to unlock/relock a line.

Thank you,

George

The .NET API provides for this using PipingProject.DataLinksManager3d.LockLineGroup(lgRowId, doLock, true).

I released a utility to lock/unlock linegroups a few years back that appears to still work but it takes a selection for input so I'm not sure it will be helpful. You can get it here if interested: https://app.box.com/s/8zrunu2cqeaci8wdmuqeygct6un8rg59

Thank you for the share and the PipingProject.DataLinksManager3d.LockLineGroup(lgRowId, doLock, true) I can't do anything except write my own stuff here, heavy lockdown, so this is perfect.  Awesome and thank you.
