11 Free BIM Software Tools to Consider

Building Information Modeling (BIM) is the digital representation of the physical and functional properties of a built structure or environment. Professionals working in the architecture, engineering and construction (AEC) industries can dig deeper into the design process together with this shared knowledge resource. Building Design and Building Information Modeling (BIM) tools help professionals plan, design, schedule, manage and budget building and infrastructure projects.

Benefits to implementing BIM include:
  • Quick, cost-efficient, quality drafting. Instead of translating multiple 2D drawings and plans into a designed structure, teams can work more efficiently together from 3D models.
  • Improved collaboration, scheduling and cost. By facilitating testing and analysis during the design phase, BIM is changing the way teams work together. It’s easier to identify and correct building errors during the design phase before too much time, effort or money has been lost.
  • Risk mitigation. Instead of just passing along information or models from one team to another, teams share information in real time while working through problems and conflicts to develop solutions in tandem.
  • Improved building life cycle maintenance. Models lay the virtual groundwork for the actual structure and can help inform management on proper maintenance and general upkeep over the lifetime of the building.

Whether you are a seasoned professional or student learning the ropes, BIM software provides 3D building work processes as well as data, change and operation management solutions.

Our list of 11 building design software solutions is divided into three sections:
  • Free
  • Free for new users
  • Free trials available

There are a few products entirely free of cost; others offer free academic licenses to students and institutions. The remaining provide free trials for users to test and compare products.

“It’s really good for architecture students as you can have all the drawing that you need for your study project in one file. You can export files in different ways and can also perform sections and 3D visualizations easily. If you are a student or an educator, you can get a free 1-year license from Graphisoft, which is very nice. Or you can start with a 30-day trial license, also for free, to help you decide if it is the right program for you.” — Anna P. in an ARCHICAD review
