This 3dsMax utility script was created around 2014 to help\improve legacy workchain difficulties.
Workchain implied exporting 3ds Max models to separate files=parts for consequent in-program usage.
Details:
bold = label on attached image
-
Models had mostly no distinct edges (mostly curved) and had high amount of poly's for 2014 (~50 000).
-
As an example, how workchain divided model, there are 3 parts on image: p1, p2, p3. Actual amount of parts was around 150, i.e. it was not possible to do proper check-ups manually.
It was additionally required for some seals to be independent, i.e. to be able to load in program only some sets of parts. -
It was required for some tasks to completely join model and to work with it like with solid seal-less object.
This means dividing it back before or during export. -
While seals like s2 provide little difficulty during these operations, in many scenarios seals like s1 were strong problem.
Normals on them were displaced during modelling in Max (especially during Weld - UnWeld),
default import-export also implicitly changed them and model after import had seals like s1' -
It was necessary to check/prevent a number of possible human mistakes like hanging vertices, hanging edges on seals, unoptimized model parts, incorrect/inconsistent names, etc
However, this script was used just necessary number of times, contains pair of experimental options. Nowadays (2020) approach itself/methods are probably inoptimal.
