Hi Aparna,

Just to be sure, you are trying to draw on fset 1 in the
acpc view, right?

I have no trouble with this. Here are my steps, please
let me know if/where yours differ.

1. from d1+orig, create d1+acpc
2. in acpc view mode, use the dataset copy plugin to
copy d1+acpc to f1+acpc, Zero(one)
3. draw in f1+acpc, and save it
4. use 3dcopy to copy d1+orig to d2+orig
5. move some of the markers, and transform to d2+acpc
6. (with or without d1+* in the current directory), choose
to view, d2+acpc and f1+acpc
7. open the draw dataset plugin, and edit f1+acpc

This works fine for me. Is there something that you are
doing differently?
