Unsolved Possible to reconfigure Automation car to have more breakpoints?

This is my first Automation mod

I am absolutely new to mod editing, have been modding games for years. I have created a few cars in Automation and exported to BeamNG, all worked great. expect for the body physics and breakaway points.

My question, can I use Maya to create more jbeams and removeable parts for the automation vehicles?
Can I use Maya to merge vehicles together? Body A onto Chassis B kinda thing?

Any advice in pointing me in the right direction would be amazing. Thank you

 

The only way to edit jbeams is though the node beam editor, or by hand with notepad++

 

You can use Maya to make jbeams. You would have to export them to blender then use the jbeam exporter to export the jbeam.
