Introduction

This page lists software published under a Free/libre or Open Source (FLOSS) software license. It lists many types of packages for many purposes and is surely not comprehensive as the reach of FLOSS is extensive and always growing. If you know of anything we're missing please let us know by just adding it wherever you think it makes sense.

We are not the only group trying to promote free/libre software for AEC. Here are some other software lists: Ubuntu software list for engineering (needs an update), CAELinux is a distribution, forum and software list.

General Purpose

If you're not familiar with Free & Open Source software useful for general use you can read our page on Open source software beginners

In addition, sensor states in the building model are supported by color highlighting, which ensures a quick orientation and an intuitive overview. MIT

Software Development

If you are a software developer, you may be interested in a wide variety of free software libraries available to aid development of new free software tools in the AEC industry. Tools include file format parsers, geometry kernels, a visualisation libraries. See free software libraries for AEC software development.

Extensions to proprietary software

Some software is distributed as free software, but only as an extension, an add-on, plug-in, or only operating in conjunction with proprietary software. As it cannot be used practically without proprietary software, it is not considered "fully" free software. Sometimes, though not always, they are released as open source as a marketing strategy to seem more open, or as a way to attempt to get free community contributions to an otherwise proprietary core. See the directory of free software extensions to proprietary software.
