Atomistic mechanic level design
This is the art of designing diamondoid molecular elements DMEs.
To do so there was developed a useful software tool called Nanoengineer-1 [1] [2]

Lower bulk limit design
Bigger structures where atomic detail may matter less or which are simply not simulatable yet because of limited computation power may be designd with conventional methods of solid modelling.
A vew issues have to be thought about though:
- Since we operate on the lowermost size level there needs to be set a minimum wall thickness that must not be deceeded
- surfaces should be kept parallel to the main crystallographic faces such that they will not create random steps when auto-filled with virtual atoms.

System level design
Main topics are:
- organisation of diamondoid metamaterials
- nanofactory system design
Diamondoid metamaterials (and more heterogenous microcomponent subsystems) are of high importance since they form the basis for all advanced AP products an applications.
Examples for what metameterials we might want to design are:
- elasticity emulation
- infinitesimal gear bearings
- legged block mobility for e.g. live self repair
- DME recycling
- ...
It is desirable to organize these metamaterials in microcomponents which are designed such that they allow adjustable inter-mixture of standalone subsystems. Examples for intermixture of sub-systems:
- infinitesimal bearings + chemomechanical converters + energy storage cells = chemical interfacial drive
- infinitesimal bearings + electromechanical converters + electric distribution system = electrical interfacial drive (non-mechanical)
- interfacial drive + self repairing systems + hirachical heterogenous comutation systems = very advanced APM product
In AP manufacturing systems system level design determines the mapping of the abstract assembly levels into a concrete three dimensional layout of a nanofactory.
Today (2013) it is rather diffecult to do work on this area. Lots of questions need to be answerded.
(yet speculative) advanced metamaterials.
The main topics can each be further subdevided into:
- three dimensional placement of huge amounts of standard components
- topological interconnections
- temporal organisation in a dynamic setting
- IO logistics of all the media (materials,information,engergy,...) to handle
- emulation of physical (especially mechanical) properties
A big problem at this design level is that the sizes of the diverse functional components and the locations of their connection points are yet unknown.
Helpful may be a software capable of crystallographic space subdivision (space groups) and piecewise connection of different crystal structures with compatible 2D cross-sections (plane groups). Scale invariant symmetries (fractal symmetries) are also of high relevance especially in redundancy design that is e.g. needed in artificial motor-muscles design.
