Known Issues

At the end of installation, the following error occurs.

1. Open Rhino.

2. Type EditPythonScript to open the Python script editor.

3. Close Rhino.

4. Run the installer again.

Some parts of Rhino's internal folder structure are only created after the Python script editor has been opened at least once.

I have successfully installed RV2, but when I try to initialise I get the following error.

Unknown Command: -_RV2init

1. Open Rhino.

2. Type EditPythonScript to open the Python script editor.

3. Restart Rhino.

4. Initialise RV2 again.

Python Plugin commands are not automatically recognised...

I still have unknown command error after executing above steps

It's possible that you have other broken python plugins installed previously that prevents RV2 from loading. To fix this problem, go to your rhino plugin folder and delete other plugins. The plugin folder location is: C:\Users\{YOUR_USER_NAME}\AppData\Roaming\McNeel\Rhinoceros\6.0\Plug-ins\PythonPlugins

or if you are using Rhino7:C:\Users\{YOUR_USER_NAME}\AppData\Roaming\McNeel\Rhinoceros\7.0\Plug-ins\PythonPlugins

After opening a new Rhino file, with every RV2 command, below error pops up. Did I do something wrong?

AttributeError: 'NoneType' object has no attribute 'Id'

This is a bug from Rhino side, whenever a user re-open another 3dm file, All Python Command Plugins including RV2 start to disfunction. So if you need to open a new file, you will have to always restart Rhino first.

I got this error on Mac during dev install.

error: command 'gcc' failed with exit status 1

This was due to failure to build Planarity which is a dependency of COMPAS, it requires xcode available on your Mac. Run the command below and try to install RV2 again.

xcode-select --install
