Modeler is the modeling tool part of RM Bridge Enterprise CONNECT Edition, where users can start a project or make geometrical modifications to existing models.

As a bridge-specific tool, for input, it usually takes the alignment or the local Axes as references, while it can also use Points data. All parametric Cross Sections are created as drawings where intelligence is applied via the use of Variables. These variations are set at Tables and Formulas and then applied at the Segments that could be Main Girders, Piers, Cross Members, Cables, or Tendons. The numbering of the numerical model could be automatic or follow user rules as well as groups of Elements can be assigned or named as Assemblies. For easy reference in general we work at a 2D drawing but the tridimensional model is created and can be checked in the 3D View.

It was known as GP - Geometrical Preprocessor and the data is backed up at "*!gp.tcl"
