    • Hi James,

      Are all of these available for free? The model viewer page is only for viewers that are free to use and not paid for.

      As far as I am aware both Trimble Connect and SketchUp need to be paid for. Plus Sketchup is extremely poor when it comes to supporting IFC so we wouldn’t add this to the list.

      Not heard of ARCHLine.XP but again if it is free to open an IFC we will add it.


  1. this list should also DALUX BIM Viewer
    I used most of these tools and to me, Dalux is by far the best among them with its features nad engine
