The documentation is perfectly opaque. As expected. What is the X and Y and Z axis in relation to a beam?

Easy. Check the picture.

Furthermore, now you also know what “Rotation” means in relation to a beam. Tekla does this because it is difficult for humans to define a beam using a change of basic matrix.

For more information on the code behind it, check out this post, or check out the extension methods I have published and open sourced

X vector of a beam is always the start and end point of the beam.

Yet another Tekla API gotcha.

If you wanna waste many hours wondering why your code doesn’t work – try the Tekla API!

Here is a note for the benefit of the public – where they mutate objects – which SHOULD NOT be mutated. Perhaps they have their own reasons, but the general boy-scount principle(s) should apply:

• The principle of LEAST surprise, and
• Leave things AS YOU FOUND THEM.

They voilate both, IMO:

Working with the Tekla API is just unecessarily difficult!
