I have been working up a custom tool in Grasshopper that can take your linework, apply loads in Grasshopper and transfer it into MultiFrame. Although it can’t do everything at the moment, it allows you to take advantage of the Rhino/Grasshopper modelling environment to setting up basic structures in MultiFrame.
There are 4 Files:
Put These in ..\Rhinoceros 4.0\Plug-ins\Grasshopper\Components
– AnalyseFrame.3dm (Rhino Example File)
– AnalyseFrame.ghx (Grasshopper Example File)
I have created two new components in Grasshopper under the extra tab – MultiFrame and Load.
The Load takes in several arguments
C – Curves
P – Load Points
M – Magnitude
The Multiframe takes in several arguments…
C – Curves (Must use same curve set as above)
F – Fix points that touch Z = 0
E – Load Members (Get From Load Component)
S – Position on Member (Get From Load Component)
M – Magnitude (Get From Load Component)
U – Update. (Default to False, Once everything is connected, switch to True to activate Multiframe)
Once update is set to true, Multiframe will launch and start constructing your Rhino Geometry with Loads and Load Cases – Fixing anything that is touching the ground as a fixed support – ready to analyse.
