Break multiple lines along boundary

[mscottJXFFG]

I'm looking for a way to break large numbers of lines along a boundary. I could use the BREAK command to break each individual object, but this becomes quite tedious when I have several hundred lines that cross a single boundary. I would like to define this boundary as a spot where each line crossing it should break. Thanks for any suggestions!

Try this.  If you put something like "break multiple" in the Search window there, other possibilities come up, in case some do what you want better than others.

Do you have AutoCAD Map?
