V0.18.03.14 - Solved the internet problem in V0.18.01.30

This is a lite BIM tools for grasshopper1.0 in Rhino6 and Rhino-WIP which focuses on architecture and urban design. This is a beta version, maybe some bug will cause caculation error. Don't fully trust the data for serious commercial until the 1.0 Version release.

Make sure your computer can connect Internet and visit github. IronPython version needs to be 2.7.5 exactly. Check this in control panel - installed program.When you install IronPython 2.7.5,  make sure click IronPython-IronPython-GACAssemblies-Entire feature will be unavailiable in the CUSTOM SETUP page. Otherwise you will get an error said No module named LiteTools_Basic... while loading grasshopper.

Please decompress this plug-in under the GH components Folder. (Grasshopper - File - SpecialFolders - Components Folder)

This plug-in has three significant features:

  1. You can generate building form and statistics through curves which are very easy to create and modify.
  2. You can use this GH plug-in without any GH knowledge.
  3. Data and form are generate and display together, which means you can control this design statistics precisely at very early stage.


  • New building forming function.
  • New display mode.
  • New help file and examples.
  • Basment support.
  • Area calculation bug fixed.


Also if you have any questions or comments I would love to hear from you. Either post a message on this site or email directly to
