Civil Engineering design software list

Hi Civil Engineers!
I am posting a few Open Source software for your CAD. Feel free to share your own software list in this thread.

FreeCAD
FreeCAD is a general purpose feature-based, parametric 3D modeler for CAD, MCAD, CAx, CAE and PLM, aimed directly at mechanical engineering and product design but also fits a wider range of uses in engineering, such as architecture or other engineering specialties. It is 100% Open Source and extremely modular, allowing for very advanced extension and customization

LibreCAD
LibreCAD is a free Open Source CAD application for Windows, Apple and Linux. Support and documentation is free from our large, dedicated community of users, contributors and developers.

Simulation of Urban Mobility
SUMO is an open source, highly portable, microscopic and continuous road traffic simulation package designed to handle large road networks. It is mainly developed by employees of the Institute of Transportation Systems at the German Aerospace Center. SUMO is open source, licensed under the GPL.

FRAME3DD
FRAME3DD is a program for the static and dynamic structural analysis of two- and three-dimensional frames and trusses with elastic and geometric stiffness.

rattleCAD
A graphical tool to design a bicycle (s) geometry and derive drawings from its configuration

Libre Mechanics
Libre Mechanics its an Open Knowledge project created to offer a useful platform of information related with the development and research of Mechanical Engineering themes and similar fields, higly related with the use of Open Source and Software Libre tools.
