I need a nudge in the right direction. In the example file is a parent object and some child objects.
What I need is to compare the volume and surface area of the parent to the volume and surface area of the children (excluding the parent intersections).
I have tried this approach, but it seems to be so heavy that I can´t even compute the example file geonetry (turned into mesh). Besides – the “wrapping” isn´t all that precise for concave shapes. By the way the precision ought to be around 5% both ways.
My guess is that meshes are the way to go because attenpting to join and split complex and sometimes slightly misaligned nurbs surfaces is quite an undertaking manually (being the reaspon for this script). Instead a mesh envelope that follows various unjoined (almost random) surfaces seems like a good idea.
Which way should I look? Does this need to be scripted from scratch?
