Currently it does not support to directly copy and paste the draft view. But there should be one workaround that we could copy the sketch geometries within the draft view, then paste them for new draft view.
Copy and pasting the sketch geometry is the easy part. On the draft view there are also dimensions, leaders and notes. I can copy/paste the notes and leaders to the new drawing, but then I have to recreate the dimensions. Its possible to get the draft view to a new sheet, but its just more difficult than it should be.
