Deform tool (NOT deformation tools) in the drawing tab? what is it?

I was looking through some of the button options for the Drawing View when I found something called Deform. At first I thought it was a sub-option that would be listed under, say, the Pencil tool, but instead it has its own set of Tool Properties with buttons that say “Selection”,“Setup”, and “Deform”, and a host of other options. I tried a few things, but I can’t seem to get it to do anything? It only appears to be listed as an option under the Drawing View. Thoughts?

I tried the Deform tool, I found Deform tool don’t have any effect in the Toon Boom Harmony 10.0.
I tried the Toon Boom Digital Pro, found that the Deform tool is used to adjust the brush line.As shown in figure:

Yeah, thats the icon. I can’t seem to get it to do anything though. I’ll scope out the documents on Studio to see what I can find on it. Thanks!

This is an experimental feature that has been deactivated. The icon for it should not be available. It will be removed in future version.

Ahh right on. It sounded fun anyway hah
