universal beam universal column and RSJ

the kwahoo spring will become famous in history, a bit like the pythagore theorem or the columbus egg... Generations of students will study it and try to reproduce

The male CADDer's most basic needs in life, ..... food....sex....and of course a Helix!


This is a steel Universal Beam (often referred to as an RSJ) modelled to the Australian standard. The size is 250UB37. This means 250mm high over all, Universal Beam (there is also a Universal Column in the Australian Standard) and approximately 37Kg/m.

Modelled in FreeCAD PartDesign, padded sketch 1m long.

The Australian standards data came from this web site below: -

I thought about beams (and other normalized things) creator few weeks ago. FreeCAD could get dimensions from external spreadsheet, create drawings and calculate mass properties (mass, inertia center etc.). Here is first ugly test The aim is: put some numbers in the sheet and get pretty 3D model and 2D drawing eg. of beam.

But there are two problems:
- pyUNO bridge, driven by command line, isn't friendly for end user,
- lack of dimensioning and x-hatching in Drawing module.
