What clue? Normally I should take the time to do a complete test with an old project within MiniB3D, but I fear that I don't have enough time budget for this. Either I do it with one or the other. MiniB3D is what I would prefer, because I could use the gained knowledge and experience for future projects (and quest updates cost ~ 400€) Sure it's great, but every update costs the same or more and the new version is due in 5-6 months. Unfortunately I can't wait so long. But if I don't see any positive responses before I have to send my calculations I will have to go the secure way with Quest3D.
