Hi
I have this idea and I do not know if it is doable. I tend to think that it is because we have couple tools to accomodate.
Currently there is no way of measuring stuff inside ZBrush at least in precise way. I know I can get some pixol info but that is irrelevant sometimes. So what I am hoping that we can establish some measurement tools by using transpose handle. Basically transpose handle can be used as a ruler or a measurement tool. And since it can snap to surface vertices it can even be a precise measurement tool. Anyways here is the list of presicion tools that can be created for Zbrush
-Screen Ruler. This can be a background image that is created by a script. The user gives the range in pixels or cm etc and the script creates an image with a ruler on top and side and puts in the background.
- 3d ruler. This one will use transpose handle and will be able to take live measurements from the model and it will spit out the distance and angle information into a window something along the lines of info window under transform
