Detailed Description

Terminal Control Block (header).

The core.stype code is DGNST_TCB.

Returned for DGNT_TCB(9).

The first TCB in the file is used to determine the dimension (2D vs. 3D), and transformation from UOR (units of resolution) to subunits, and subunits to master units. This is handled transparently within DGNReadElement(), so it is not normally necessary to handle this element type at the application level, though it can be useful to get the sub_units, and master_units names.
