I know there are multiple ways to achieve this and my approach shall most likely be similar, the same or something that others have already done - so forgive me, if l have repeated someone else’s question. (I have carried out research).
Within the attached image, the beam to column clashes (purple spheres), works fine both numerically and visually.
The beam to beam clash detection has been a nightmare to resolve. I feel l am nearly there, however, within the image only 5 beam to beam clashes exist, yet it is returning a further 2 clashes (highlighted), yet they are not clashing at all.
