• Normalise force vector?

• Stacks
• Arch
• Arch with friction
• Variations
• Corresponding examples

I got this error message from running simple_stack_rotate.json on Rhino mac. It seems that error is from artists.

I tried another example like Jenga, and I found some interfaces are not detected. Any idea?

The Rhino model is in the commit 2be9fe9

Describe the bug
After following the install instructions on the documentation, the installation of compas_rbe on Rhino fails with the following error AttributeError: module 'compas_rbe' has no attribute '__file__'.

To Reproduce
Steps to reproduce the behavior:

1. Install according to documentation
2. Install on Rhino using: python -m compas_rhino.install -p compas compas_rbe
3. Install fails with the following error:

(workshop) C:\WINDOWS\system32>python -m compas_rhino.install -p compas compas_rbe
Installing COMPAS packages to Rhino 5.0 IronPython lib:
Traceback (most recent call last):

  File "C:\Users\mingc\Anaconda3\envs\workshop\lib\site-packages\compas_rhino\install.py", line 21, in _get_package_path
    return os.path.abspath(os.path.join(os.path.dirname(package.__file__), '..'))
AttributeError: module 'compas_rbe' has no attribute '__file__'

Desktop (please complete the following information):

• OS: Windows 10
• Python version 3.6
• Python package manager Anaconda

Additional context
The problem seems to be caused by a PLACEHOLDER file in the source of compas_rbe, after deleting the file locally, the install works correctly.

How do I effectively reload all submodules while working on rhino mac?

For example, the change I did with compas_rbe.rhino.artists does not effect unless I restart rhino or manually reload the submodules as below.

import imp
# the deeper module has to be reloaded first.
imp.reload(compas_rbe.rhino.artists)
imp.reload(compas_rbe.rhino)

from compas_rbe.rhino import AssemblyArtist

• check different solver and compare results

• check cvxopt and windows (cvxpy doesn't work in windows) (Ursula's code works in Window?)

• visualise friction vectors
• visualise friction interface color
• resultant normal force
• resultant friction force

• planarise
• planarise and change the geometry
• combined interfaces?
• offset interface inward for safety factors

Feature Request

As a newbie, I want the Installation Instruction to be more detailed so that installation is less painless.

Details

Include the information for installing C++ 14.0. The following link works to install the build tool without installing Visual Studio. (According to this StackOverflow answer)
http://go.microsoft.com/fwlink/?LinkId=691126&fixForIE=.exe.

Include the line for installing for Rhino for Rhino v6. Add note for people who have already installed compas.
