The resulting analysis can then be viewed directly in SketchUp. One of the main benefits of OpenStudio is its SketchUp plug-in, which allows users to create models in Trimble SketchUp and then analyze them in OpenStudio. īuilt on the EnergyPlus simulation engine, this open-source energy modeling solution was originally developed by the National Renewable Energy Laboratory. FreeCAD supports a variety of file formats including DXF, OBJ, STEP, and IFC. It also incorporates drafting tools in a 2D Workbench for creating traditional 2D documentation and drawings. FreeCAD contains an Arch Workbench that provides BIM-specific workflows within the software. It is also a parametric modeling tool so users can make changes by directly editing the model’s history. Below, I list seven options to consider, ranging from 3D modeling tools to energy analysis applications.įreeCAD via a Creative Commons License BIM Workbench can be installed in FreeCAD from the Addon Manager.įreeCAD provides a robust set of 3D modeling capabilities in an open-source application. The promise of free, open-source software may sound great, and, importantly, many open-source applications are suitable for the design workflow, particularly as architects take on more digital tasks. Some well-known open-source projects include the Linux operating system, the WordPress web publishing platform, and the audio-editing application Audacity. Often the goal of these projects is to develop applications that can accommodate multiple viewpoints and ways of working. Unlike commercial software, which typically has a protected source code and proprietary file formats, open-source software projects are not profit-driven and encourage users to modify and share their code with the wider community. Open-source software is released under a specific license that gives users the right to download, use, or change the software and its source code. One way that architecture and design firms can alleviate this financial burden and still have access to the software and technology necessary to run their businesses is to explore open-source alternatives, whose numbers have increased in recent years. As a result, companies across industries have seen their monthly software expenses grow.
Many in the software industry have moved from selling software as a one-time purchase-which would remain usable after it was fully paid for-to a recurring monthly subscription model-in which the tool loses functionality if the user stops paying. With many software applications and file formats becoming de facto industry standards, firms are increasingly tied to commercial software publishers. Software is increasingly a top expense for architecture and design firms. Cristian Taborda Mejía / 77 Render Studio Rendering created with Blender Cycles
