The basic concept of the assemblies is the hierarchical structuring of an ELITECAD drawing. An assembly defines a combination of ELITECAD components (models and objects) into a logical unit.
A component can be a single model or an object that is composed of several models. Objects are 3D objects that are created using several models (e.g.: 2-view-solid, boolean operations).

An assembly can also have sub-assemblies. Thus, a structure tree can be formed, the depth of which is arbitrary.
The top assemblies are also known as main assemblies.
