This employs Google SketchUp as a front end graphic interface for the analysis.

A copy of the program code, and more information, can be found here,

We have defined a general template for a SketchUp function to draw
3D beam sections. Four example functions are provided here to demonstrate
the way in which to construct frame geometry.

These functions build a 3D tubular section and store specific attribute
data with each section. Our next step is to extract the attribute
data and use this to automatically generate the input to the
Frame3DD program.
