I have the electronics modeled and layed out. A laptop, a raspberry pi, a phone, a portable battery, and a portable satellite dish. All made in 3dsMax.
Looks like they tried to expose it with MaxPlus python api. But I can’t get it to work. help.autodesk.com/view/3DSMAX/2016/ENU/?guid=__py_ref_class_max_plus_1_1_snaps_html
3dsMax has a little-known feature(it seems these days) called the official documentation. The hotkey is F1. There is a section dedicated to explaining the basics of smoothing groups.
