I am trying to find a way to add a rectangular baffle starting with a vset. Adding the baffle has to be done completely through keystrokes and I can only seem to find methods using the mouse. Are there other methods for creating a baffle outside of what is in the cell tools?

How about the cfind commnad?

start with a vset cset news vset face vset news edge cfind, baffle, ictid, nv

You'll need to play some games to get an appropriate vertex nuber (nv) - it needs to be part of the original set but not in the second vset. A few loops, the graph registers for a storage area, & some logic should do the trick.

If you want a baffle bouondary, you can use cfind with the shell option & then use bshell to convert the shells to boundaries.
