A couple of ideas for your consideration (note that Blender's main competitors are Maya and 3DSmax, owned by Autodesk)….
Ever wonder why most buildings look so blocky, inside and out? One of the reasons is that Revit, Autodesk's architectural design software that dominates the industry, has only five modeling tools. Yes, you read that correctly… five! Fortunately for architects who are fed up with Revit (over the past few years, hundreds have signed open complaint letters to the CEO of Autodesk), the BlenderBIM Add-on, which started four years ago by Dion Moult and Thomas Kreijin, is bringing open-source technology to the literal brick and mortar industry. Blender has been used for years to do architectural visualization. The BlenderBIM Add-on is far more than pretty pictures; it provides a comprehensive, open-source, suite of tools for building design, construction, and operations.
The BlenderBIM add-on is really picking up speed bringing tools to architects, structural engineers, mechanical engineers, electrical engineers and plumbing engineers (basically, everyone involved in designing buildings). The BlenderBIM add-on also brings costing and scheduling tools for the people who build the buildings and tools for the people who operate and maintain buildings. What makes all these tools special is that they are built on an open industry standard data schema, maintained by an association called BuildingSMART. The open industry standard data schema is very important because it means that users own and control their own data, not Autodesk.
Most of the tools are still alpha software (not for the faint of heart), but the BlenderBIM Add-on has already been used by architects to get government approvals on many small projects.
The BlenderBIM Add-on typically has nine small enhancements or bug fixes each day, with a stable release every two months. It is moving fast, but there is a long way to go.
One of the contributors to the BlenderBIM Add-on is Bruno Postle. Bruno designs metal sculptures using Blender and then uses the BlenderBIM Add-on to create the files that fabricators use to build them. Bruno recently built a collaboration tool for the BlenderBIM Add-on using Git, because many people in the industry are frustrated with Autodesk’s expensive, proprietary cloud solution.
