How to move part of a level to another level?

Hi,

I need to move a section of drawings from level A to level B.

I tried selecting the string of drawings in timeline and dragging them over to the other layer. I also tried selecting the drawings in X-sheet and cut and paste to other column, but both times drawings show up blank.

I guess I’ll need help with that. ???

thanks…

Actually, scratch that…

I figured it out.

(I didn’t see the drawings because they were outside of camera, because of a pan).
