Shop Doc Variable for OVL of Tool Assembly? Also Tool Image?

[Dbfoster24]

I am trying to customize my shop documentation output and need some help. Does anyone know the mom variable to output the overall length of tool assembly (see attached picture (tool holder+tool length))? Also, the mom variable for the tool radius? I have the variable for the tool diameter and it works but when I input ${mom_tool_radius} nothing is displayed. Additionally, I am trying to output images of the tool assembly (holder+tool) with and in the corresponding tool number row/column. Do I need to take images of the tools and save them to a particular directory/folder?

Thanks you!
