We are
currently writing a SketchUp interface to the FRAME3DD analysis
program,
produced by Professor Henri Gavin at Duke University.
FRAME3DD is a
frame analysis program, while SketchUp is a 3D modelling package.
Above is an
example of a simple trailer frame with loads and constraints applied.
The frame is made up of 8 rectangular beam sections and has 5 loads
applied.
Four constraints have been applied to represent the points where an
axle would attach.
Below are links
to SketchUp, Frame3DD and the current version of our interface
functions.
The contents of
the current "files.zip" archive are as follows;

Below is another example of a simple frame. This shows a pyramid frame
comprising 4 members,
with a single vertical load and each base point constrained.
Once we've
completed the interface we will use this with Frame3DD to analyse
various chassis frame designs.
