RW3DM - Rhino Extensions for NURBS-Python (geomdl)
RW3DM project provides executables for exporting and importing OpenNURBS/Rhino .3DM files in JSON format. It utilizes OpenNURBS library for reading and writing .3DM files and JsonCpp for importing and exporting geomdl geometry data.
Installation and Updating RW3DM
You can download the precompiled binaries under Releases.
If you prefer to compile the binaries on your own, you can follow the following list as a reference:
- Clone the repository:
git clone https://github.com/orbingol/rw3dm.git
- Change to the directory of the local repository:
- Update submodules:
git submodule update --init
- Create a build directory for CMake-generated files, e.g.
- Enter the build directory, e.g.
- Run CMake to generate build configuration files, e.g.
cmake ..or use CMake GUI
- Compile and install
- For Windows, you will find the Visual Studio project files under
- After opening Visual Studio, choose
Releasefrom the build combobox, then right click on
- For Linux, run

- You can modify the install directory using
RW3DM_INSTALL_DIRvariable while configuring the project with CMake
- Go to the install directory, e.g.
cd installor the one you configured with CMake during step 6
- You will find the executables inside the install directory
If you prefer to update the compiled binaries on your own, you can follow the following list as a reference:
- Pull the latest commits:
git pull --rebase
- Update submodules:
git submodule update
- Repeat steps from 5 to 9
Notes on installing and updating
- Visual Studio 2017 is required to compile OpenNURBS
- Please install C++ support on Visual Studio as it is not installed by default
- Choose Release as the build configuration inside Visual Studio before you compile the package
- It is tested with gcc 7.3 and it should be compatible with any gcc version supporting C++17
- Please remember to install the compiler packages for your Linux distribution
