Cornerstone Tools Cobb Angle

Greetings

I have been working on OHIF v2 for a while, and now we’re updating to V3.

I have a question regarding the cornerstone tools library:
In the v2 it was accessible via node modules, and in order to add tools I modified the library and then put the built project in the node modules.

I do not understand how to do the same with V3, and I need some help in doing so.

I wanted to start by studying the cobb angle, as it shows the incorrect angles when I use it (I am using v3.7.0) and then adding other tools in due time.

Any help is greatly appreciated.
