By default, positions and orientations of all 3D elements in a document are calculated using its Global Coordinate System (GCS). Instead of GCS, you can create and use Local Coordinate Systems (LCS) for calculating particular 3D elements. LCS can be created using the following command:

A local coordinate system (LCS) is an auxiliary 3D construction element, that allows positioning 3D objects in the space. LCS's are widely used in 3D modeling, for example, for building 3D assemblies, copying 3D bodies, defining transformations, etc.
The size of an LCS's image is controlled in the command Set Document Parameters, on the tab 3D > View, by the parameter Size > LCS.
On the basis of the LCS it is possible to create special 3D construction elements of the T-FLEX CAD — 3D connectors. 3D connectors are used for attaching fragments when creating 3D assemblies. They represent themselves the LCS of a special type which are able (besides performing the function of attaching the fragments) to pass the values of the variables of one 3D fragment into another fragment. The use of the 3D connectors significantly simplifies positioning of the parts and matching of the fragment parameters when designing the assemblies.
The image of the 3D connector in the 3D window is analogous to the image of the standard LCS, but the axes are marked with “volume” arrows.
