The lightwright vs. is standard in the industry, you will find most or all focus charts are finalized in lightwright.
The trick is to lay out focus tape so you get co-ordinates. So when your designer is focusing the light you note where they stand on a grid; lets say 1,A then you record that. Next you need to note how the fixture is focused and then note any shuter cuts.
Lightwright lets you do all of this and you can draw the shutter cuts it also lets you keep all your documentation in one place. So im not to sure what you dont like about it. More info would be necessary to help you out.
One other thing is always as the ALD do focus charts as the focus is hapening. Aswell do it by hand first on sheets of paper its quicker and you can make updates quickly. Then input it into lightwright.
