Splitting a Curtain System / Grid

[artitech]

I have applied a curtain system to the face of a solid form (had to start with a solid because of th odd shape of my building). I want to terminate part of the curtain grid one one of the faces, that is, along one face I only want say 2/3 of it to be curtain wall, not the entire face. What's the easiest way to do this?

One thought was just to leave the portion of the curtain system I want gone empty of any mullions and to use empty panels...???

Edit your mass. In sketch mode, split the line defining the mass face at the desired point. ( 2/3rds in your case )

You will probably need to delete the existing curtain wall, tehn you can select just the portion of the mass to the split line to create a new curtain wall.
