Design software for overhead contact line systems

Design results

Through specific snap points on the individual design objects, the necessary dimensions for the correct reference points can be quickly generated. The data can then be exported in the form of layout or situation plans and cross-sections for each construction phase, as well as in the form of value tables such as catenary tables and tables for the traction power lines, for example. With just a few clicks, it is also possible to create tables from the SIGNON OLAcad drawings which contain the coordinates of the mast-ups or complete mast and foundation tables according to client specifications.

SIGNON OLAcad furthermore comprises programmed functions for the export of the digital


drawings according to CAD interface descriptions of various clients.

Based on the 3D model, views from every angle can be created. Without much effort it is also possible to create detailed assembly drawings for complicated assemblies, which thus explain what the designer had in mind to the assembler of the contact lines.

Evidence of the statics is exported directly from the program to a signed PDF/A document. This document contains all the necessary entry and export values, enabling the static inspectors to verify the values using their own calculation methods.
